Lift AI is building essential software for the elevator industry, a sector where traditional methods like paper inspection reports and faxed maintenance tickets are still common. They are uniquely positioned, with the CEO's family having 40 years of experience in the industry, ensuring they understand the market's specific needs. The company currently manages approximately 5,000 properties and has over 1,000 IoT deployments on elevators across the US. Their platform comprehensively handles asset management, maintenance workflows, contract tracking, and incorporates an AI pipeline to extract structured data from industry documents.

Job Position Available

Lift AI is looking to hire a **Senior Software Engineer**. This is a full-time, remote position open to candidates in **US timezones**, and individuals located in **Latin America or Canada** are also welcome. The role offers a base salary of **$100,000** along with **0.50–0.75% equity**. The team explicitly states that while $100K is below big-city market rates, the equity is substantial due to growing revenue and ~5,000 customers. Growth within the company means an expanding scope of ownership, with compensation growing accordingly, as they are not focused on titles or hierarchy.

As the third engineer on the team, you'll be joining the CTO (who actively codes), an experienced engineer, and the Chief of Product. There's no dedicated QA or DevOps team, meaning "you own what you build." Your first major project will involve designing the migration of an acquired field maintenance product from its current Firebase/Firestore backend to Lift AI's Django/PostgreSQL stack, including finding a replacement for Firestore's offline sync (ElectricSQL is being considered). Beyond this, you'll be actively involved in architecting new AI features, such as an invoice dispute agent.

Candidates should have **5+ years of experience** with Python (Django, Flask, or FastAPI) and React/TypeScript in production. A key requirement is having built something from architecture to deployment independently. This role is ideal for engineers who were among the first few at a startup, senior engineers tired of excessive process overhead, or agency professionals looking to deeply specialize in a single product.

The work environment is async but collaborative, primarily utilizing Slack, GitHub PRs, and Linear, with occasional video calls. There are no standups, and the team follows Shape Up with 4-week cycles. The CTO will review architecture proposals for your initial ~90 days, after which you will own your domains. There is no on-call rotation, and releases are not done in the evening; when a rare issue occurs, everyone pitches in.

Technologies Used

• **Backend:** Django 5 / DRF, PostgreSQL, Redis, Django Q
• **Frontend:** React Router v7, TypeScript, MUI
• **Cloud & Infrastructure:** AWS (CDK, ECS Fargate, ElastiCache, RDS)
• **CI/CD:** GitHub Actions
• **AI/ML:** Claude, OpenAI, LangChain
• **Collaboration:** Slack, GitHub PRs, Linear

Applying

To apply, send an email to [email protected]. Please include something you've built that you're proud of and explain why.

Company URL

The company homepage URL was not provided in the posting.

Lift AI builds software for the elevator industry, where paper inspection reports and faxed maintenance tickets are still normal. Almost no one is building software for this market. We manage ~5,000 properties and have 1,000+ IoT deployments on elevators across the US. The platform handles asset management, maintenance workflows, contract tracking, and an AI pipeline that extracts structured data from elevator industry documents. Django/PostgreSQL backend, React/TypeScript frontend, all on AWS. The CEO's family has been in the elevator industry for 40 years — we're not outsiders guessing at what the market needs.

You'd be our third engineer. The team is me (CTO, I write code daily, Central Time), one engineer who's been here two years and knows the domain well, and our Chief of Product who handles the PM side. No QA team, no DevOps. You own what you build.

First project: we acquired a field maintenance product that currently runs on Firebase/Firestore. You'd design the migration of its backend onto our Django/PostgreSQL stack, including figuring out a replacement for Firestore's offline sync (we're looking at ElectricSQL). You define the API contract, our other engineer builds the frontend against it. Beyond that, we're actively building AI features. One example: an invoice dispute agent that communicates directly with service providers. You'd help architect those.

Stack: Django 5 / DRF, PostgreSQL, Redis, Django Q, React Router v7, TypeScript, MUI, AWS (CDK, ECS Fargate, ElastiCache, RDS), GitHub Actions. AI features use Claude, OpenAI, and LangChain.

We're async but not siloed — Slack, GitHub PRs, and Linear are where most collaboration happens, with the occasional video call. No standups. We follow Shape Up with 4-week cycles. I review architecture proposals for your first ~90 days, then you own your domains. No on-call rotation. We don't do evening releases, and when something rare breaks, everyone pitches in.

$100K base + 0.50–0.75% equity. We have ~5,000 customers and growing revenue, so the equity isn't a lottery ticket. $100K is below big-city market rate and we know that. We're not focused on titles or hierarchy. Growth here means the scope of what you own keeps expanding, and comp grows with it.

5+ years experience. Python (Django, Flask, or FastAPI) and React/TypeScript in production. You've built something from architecture to deployment without someone telling you how. If you've been engineer #2-5 at a startup, or you're a senior engineer tired of process overhead, or you're at an agency and want to go deep on one product, this is that kind of role.

[email protected] — send something you've built that you're proud of, and tell us why.

Job positions available

They are looking for an AI-Native Technical Operations Lead. This is a contract-to-hire position with a salary range of $90,000 - $150,000 per year, plus equity. The role is described as being akin to a "studio engineer to a recording artist," taking ownership of environment preparation, QA, testing, CI/CD, compliance documentation, and 30-40% independent development to allow engineering leadership to focus on high-leverage product work. This is a ground-floor equity opportunity.

Technologies used

Candidates must already be actively building software daily with AI coding tools such as Claude Code, Cursor, or Copilot. General requirements include full-stack experience, strong QA discipline, and comfort with DevOps practices (Docker, CI/CD, cloud). The role also requires a polyglot background across various languages and frameworks.

The position is preferably onsite in Miami, FL, but remote within the US will be considered. Relocation assistance to Miami, FL, will be provided if needed.

Candidates should have 3-7 years of full-stack experience, a strong QA discipline, DevOps comfort, be polyglot across languages/frameworks, and be self-directed. A hard requirement for applicants is demonstrating active use of AI coding tools in projects within the last 60 days.

Hard requirement: you must already be building software with AI coding tools daily (Claude Code, Cursor, Copilot). Not interested in AI — actively shipping with it. If you can't show us something you built with AI tools in the last 60 days, this isn't the right fit.

Company Name: DoStuff

Company URL: Not available

Job Position: DoStuff, founded by Scott, is actively seeking a hands-on Retention Product Engineer (Full-Stack). This role is pivotal for their growing membership product, DoMORE, which provides members a pair of event tickets for $7/month. As a Retention Product Engineer, you will own the entire engagement-to-churn-reduction process from end-to-end. This involves analyzing cohorts, defining the retention north-star metric, shipping product and lifecycle experiments yourself, and meticulously measuring their impact. Scott emphasizes that this is neither a PM-only role nor a pure engineering role; instead, you will own the full loop: insight → build → measure → iterate. Retention is considered the highest-impact opportunity in the business, and this role comes with real authority to ship.

Salary Range: Not specified

Technologies Used: The current technology stack includes React for the frontend, Ruby on Rails and Elixir for the backend, Postgres for databases, and Elasticsearch. They also utilize proprietary lifecycle tooling for email, SMS, and in-app (web) communications. A key responsibility for the new hire will be to help install missing "plumbing," specifically feature-flagging and experimentation frameworks, as these are not yet in place.

Location & Requirements: This position offers flexibility, allowing work to be done either in Austin or remotely, with a crucial requirement that remote candidates must be located within US time zones. The preferred arrangement is a contract-to-hire. Candidates should have experience with the technologies listed and be eager for a role that combines product ownership with engineering execution in a high-impact area of the business.

Applying: If you have experience with the mentioned technologies and this opportunity "sounds like fun," please reach out to [email protected]. Make sure to include something in the subject line that lets him know you're "real and interested." THX!

About Shinzo

Shinzo is dedicated to building the decentralized read layer for blockchains, directly addressing the paradox of "trustless" applications relying on centralized indexers like Alchemy or The Graph. They aim to rectify this by embedding indexing directly into validators, thereby transforming blockchain data into a cryptographically verifiable public good. This eliminates the need for trusted intermediaries, API keys, and concerns about rate limits. The company is currently pre-mainnet and emphasizes its real technical differentiation, asserting they are not "another 'decentralized' project that's actually three EC2 instances in a trench coat." Shinzo understands and seeks to solve the frustrations developers face with deprecated API endpoints and broken subgraphs, valuing what candidates can build over their academic background.

Job positions available

Shinzo is hiring for several full-time roles. Salary ranges for these positions are not specified:

• DX Engineer - Indexer Migration
• Senior Blockchain Indexer Engineer
• Senior Cross-Chain Smart Contract Engineer
• Protocol Engineer - Blockchain

Technologies used

The technology stack at Shinzo includes: Go, Rust, WebAssembly, Merkle CRDTs, recursive SNARKs, LibP2P, GraphQL, and Cosmos SDK/EVM.

Location and Requirements

All positions are full-time and remote, open to candidates located in the USA or Canada. Shinzo prioritizes practical building skills over formal academic qualifications. Information regarding visa sponsorship is not available in the posting.

We're building the read layer for blockchains. The irony of "trustless" applications depending on centralized indexers like Alchemy or The Graph isn't lost on us—we're fixing it.

Shinzo embeds indexing directly into validators, turning blockchain data into a cryptographically verifiable public good. No trusted intermediaries, no API keys, no "please don't rate limit me" prayers at 2am.

Stack: Go, Rust, WebAssembly, Merkle CRDTs, recursive SNARKs, LibP2P, GraphQL, Cosmos SDK/EVM

We're pre-mainnet with real technical differentiation—not another "decentralized" project that's actually three EC2 instances in a trench coat. If you've ever been mass-migrated off a deprecated API endpoint or debugged why your subgraph stopped syncing, you understand the problem we're solving. We care more about what you can build than where you went to school.

Herakles, a Munich-based defense startup, is currently seeking a **Founding Engineer** to join their mission. You can learn more about them at herakles-defense.com.

The challenge they present is formidable: detecting, tracking, and physically intercepting an FPV drone flying at 100 km/h using only on-board compute – no Cloud allowed. This is described as one of the hardest problems in counter-drone defense, aiming to build the "Iron Dome" for infantry to stop FPV kamikaze drones.

For this role, they are looking for individuals with strong skills in Drones, Embedded Systems, Computer Vision, or Robotics. A key requirement is a mindset for pushing hardware to its absolute limits, demonstrated perhaps by experience with platforms like Nvidia Jetson or Hailo-8, even if Qualcomm QRB5165 Flight controller + NPU SoC is unfamiliar.

The core technologies involved in this ambitious project include:

• Computer Vision with YOLOv8 Nano on Qualcomm QRB5165 Flight controller + NPU SoC.
• Autonomous guidance using advanced control loops such as Proportional Navigation, MPC, or PID/LQR.

This position offers a **Founding Engineer** role with full tech autonomy and includes **Equity** as part of the compensation package. The work can be performed from **Munich** or **Remotely**. Specific salary ranges are not provided.

If you're interested in tackling such hard problems and contributing to a vital defense mission, you can find the full details and apply directly at herakles-defense.com/founding-engineer.

Company name: Language REACTOR

URL to company home page: No direct URL for Language Reactor was provided in the posting. The contact email uses the domain dioco.io.

Job positions available: Language Reactor is seeking a Coding Partner. The main coder on the project is looking for a collaborator to share the development load and allow for a more ambitious scope for their language learning software. No salary range was specified.

Technologies used: The core codebase is primarily Typescript, and applicants with backend knowledge will find it a plus. The development workflow heavily incorporates AI tools like Claude and Cursor.

This position is primarily remote. However, the main coder travels frequently across Europe and Asia, and values occasional in-person work. While no explicit country, state, or timezone restrictions were mentioned, candidates should be open to periodic travel for collaborative sessions.

Language Reactor develops software for learning languages, focusing on creating powerful tools rather than content, though the line between code and content is blurring with the advent of Large Language Models (LLMs). The project is financially stable.

The ideal candidate will possess sound judgment and taste, capable of planning and executing tasks independently. Strong communication and coordination skills are essential for managing complex changes, along with ingenuity and resourcefulness.

To apply, or if you have a project that overlaps in scope with Language Reactor, please contact [email protected].

REMOTE mostly, but I travel often (Europe, Asia) and it's good to work in person time to time.

We make software for learning languages. The focus is on making tools, rather than content. But actually, the line between code and content is blurring with LLMs.

I am the main coder on the project and I'm looking for a coding partner to help spread the load and allow more ambitious scope. Project is solid financially.

Most of the codebase is fairly decent Typescript. Backend knowledge a plus.

I need someone with sound judgement and taste that can plan and execute independently, but that also can communicate and coordinate complex changes well. Ingenuity and resourcefulness.

I use Claude/Cursor extensively.

I'm quite interested to hear from you if you have a project that overlaps in scope with Language Reactor.

Summary of Opportunity

Work Location and Requirements

Application Information

We’re building the biggest second-hand bike shop in the world.

Upway is the leading marketplace for refurbished e-bikes across Europe and the United States.

In 3 years, we grew from 0 to $200M GMV. The tech team grew from a small senior core to ~12 engineers in 2025, and we plan to grow to ~30 engineers in 2026. We also raised a $60M Series C at the end of last year to support the next phase of the company.

This is not a SaaS. We operate warehouses, handle real inventory, and build software that connects logistics, product, and marketplace dynamics at scale.

We’re looking for engineers and product people who like tech as much as business, people who want ownership, enjoy making product and business trade-offs, and care about outcomes, not just systems.

We work with a Shape Up–inspired methodology that gives teams real ownership: shaping problems, building solutions, shipping, and learning from real-world impact.

Stack: TypeScript | NestJS | React | Shopify | PostgreSQL | GCP

Why it’s a great time to join:

- The organization is switching gears: bigger ambitions, broader scope, more responsibility.

- The challenges are growing with the team: product, marketplace, and operational complexity.

- High ownership environment where engineers influence technical and business decisions.

- Paris on purpose: at our current pace, working in person is a real advantage.

About the role and requirements

Applying to Evercred

1. Your approach to the trial problem (3-5 sentences)
2. Why 20% equity interests you vs. full cash
3. How you'd use AI tools to accelerate the week

THE ROLE: You'd own agent orchestration, monitoring, and ML operations as founding technical leader. We have agents built by external agency launching in 2-4 weeks. You'd evaluate their implementation, build operational infrastructure, and own the technical strategy as we scale from 0 → thousands of verifications monthly.

THE OPPORTUNITY: - 20% equity (founding team level, 4-year vest) - $20K/month cash (adjustable based on equity preference) - Clear path to Series A: $1M ARR by summer 2025 - Own agent infrastructure for industry-disrupting product - Work directly with CEO/CPO, high autonomy

THE REALITY: - 3-4 month runway (aggressive growth targets) - Remote/async-first, US-based for timezone overlap - Paid trial week ($1,400) - mutual evaluation for partnership - Need production ML/agent experience - Must move fast intelligently (AI-assisted development expected)

THE TRIAL: Week 1: Evaluate third-party agent code, build monitoring infrastructure, or pivot to corrective strategy if code needs work. Testing judgment + execution + communication.

LOOKING FOR: - Production experience with LLM agents or ML systems - Can leverage AI tools (Claude/Cursor) to accelerate safely - Comfortable with ambiguity, short runway, high ownership - Wants equity upside, sees potential in healthcare transformation - CTO-level strategic thinking

NOT A FIT IF: - Need structured W2 role with benefits - Want low-risk established company - Optimizing for maximum cash vs. equity potential - Need multiple approval layers for decisions

TO APPLY: Email [email protected] with: 1. Your approach to the trial problem (3-5 sentences) 2. Why 20% equity interests you vs. full cash 3. How you'd use AI tools to accelerate the week

We respond within 24 hours. Strong candidates start immediately.

Healthcare credentialing is broken. Help us fix it.

We are building autonomous kinetic interceptors to neutralize the rapidly evolving kamikaze FPV drone threat.

The Engineering Challenge: We are solving the "closed-loop" problem for high-speed aerial pursuit. Our mission is to move beyond simple detection and achieve a seamless handover where visual tracking directly drives the flight control logic at speeds exceeding 100km/h.

The Tech Stack & Hardware: * Compute: Currently prototyping on Qualcomm QRB5165 utilizing the NPU/DSP for low-latency inference. * Flight Stack: PX4-based, integrating terminal guidance laws (PropNav) and adaptive control loops. * The Role: We have a hardware prototype concept that we believe is the right foundation. However, as our Founding Engineer, the technical execution is entirely in your hands. Whether we optimize the current ARM/NPU stack or pivot to custom architectures is your call.

Location & Ecosystem: We are based in Munich, Germany. While we are open to remote arrangements for the right candidate, onsite is preferred to iterate quickly with the hardware. Munich is arguably the best robotics ecosystem in Europe. Home to TUM (Technical University of Munich) and a unique density of talent, funding opportunities and testing grounds.

Who we are looking for: A builder who is comfortable at the intersection of C++, embedded Linux, and flight dynamics. If you’ve pushed edge-AI chips to their limits to control high-kinetic physical systems, we want to hear from you. The Offer: Significant founding equity, full technical autonomy, and the chance to build a critical layer of modern defense infrastructure.

Company: SpruceID (YC W21) is building a future where users control their data across the web, shifting from traditional logins to a model where platforms request access to user-controlled data vaults. This mission is particularly urgent as AI deepfakes increasingly challenge traditional identity verification methods. SpruceID aims to provide individuals with trusted digital IDs and credentials, incorporating safeguards to prevent descents into surveillance states. They are actively involved in significant initiatives, including implementing the digital ID program for the California DMV and the verifiable digital credentials program in Utah, and are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID. The company fosters a strong engineering and customer-oriented culture and seeks individuals eager to make a real impact in improving public services, digital autonomy, and user privacy.

Website: spruceid.com

Job Positions Available: SpruceID is hiring skilled engineers and has a new role open for exceptional new graduates. Specific named roles beyond this are available on their careers page, linked below. Salary ranges are not specified in this posting.

Technologies Used & Responsibilities: Engineers at SpruceID engage with a diverse and challenging technical stack, including Rust, C#, TypeScript, Swift, and Kotlin. Day-to-day responsibilities are varied and can encompass:

• Writing code in Rust, C#, and TypeScript.
• Handling mainframe dumps and interpreting policy documents.
• Responding to technical RFIs/RFPs.
• Managing on-prem environments.
• Implementing new NFC + Bluetooth protocols in Swift/Kotlin.
• Creating CI/CD processes that enforce W3C accessibility guidelines and i18n requirements.
• Rewriting lost specifications from disassembled binaries.
• Investigating stablecoin payments.
• Designing new protections for public key infrastructure.

Location & Requirements: This is a REMOTE position, with a preference for candidates based in the US. The roles are described as not "for the faint of heart," expecting individuals to work hard and learn significantly. SpruceID seeks ambitious engineers focused on achieving outcomes for customers and constituents, and who are motivated by making a meaningful, long-term impact on society. This opportunity is explicitly not suited for those seeking a quick "cool new AI startup" exit.

Application Process: To explore all available roles and apply, please visit the SpruceID careers page: https://jobs.lever.co/sprucesystems/.

[NEW ROLE FOR EXCEPTIONAL NEW GRADS OPEN]

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

Job positions available: Hack Club, a vibrant nonprofit dedicated to empowering thousands of teenagers across 140 countries to ship real projects—from games and hardware to websites and apps—is seeking a **Quality & Integrity Lead, YSWS**. Driven by the motto "by teens, for teens" and a commitment to radical trust and transparency, Hack Club supports over 100,000 teens globally by sending them free stuff in return for their projects. This role is pivotal in maintaining the integrity and quality of their "You Ship We Ship" programs, which see thousands of projects submitted monthly. The primary mission is to QA the reviewers themselves, ensuring they make sound judgments, effectively catch fake projects, and are fair to legitimate submissions. The salary for this crucial position is **$55,000 - $70,000**, and it comes with 4 weeks of Paid Time Off (PTO), as well as health, dental, and vision benefits.

Technologies used: Specific technologies are not explicitly listed for this role. The position primarily focuses on process design, quality assurance, system building, and training. The successful candidate will be responsible for designing and implementing systems capable of handling 100,000 projects per year, indicating a need for strong analytical, organizational, and problem-solving skills to manage complex workflows and ensure program integrity.

Important Information: This is an **ONSITE** position located in Shelburne, Vermont, USA, situated in an historic 1800s building. Key responsibilities include spot-checking approved projects through random sampling, auditing reviewer consistency, defining and documenting "high quality" standards, training program authors to enhance their decision-making, handling appeals and investigations, and building robust systems to scale operations. While the role's core is ensuring overall process integrity, it requires hands-on project review to gain a deep understanding necessary for effective spot-checking. No specific information regarding visa sponsorship or additional country/state/timezone restrictions beyond the onsite Vermont location has been provided. For full details and application instructions, please visit hiring.hackclub.com/38523.

Hack Club (https://hackclub.com / https://github.com/hackclub) is a nonprofit where 1,000s of teenagers ship real projects — games, hardware, websites, apps — and we send them free stuff in return. 100k+ teens, 140 countries. Our motto is "by teens, for teens" and we operate with radical trust and transparency.

Every month, thousands of projects come through our You Ship We Ship programs. Program authors do the primary reviews. We need someone to QA the reviewers — a second set of eyes who can tell us: are they making good calls? Catching the fake projects? Being too harsh on legitimate ones?

Responsibilities:

- Spot-check approved projects (random sampling)

- Audit reviewer consistency and catch patterns

- Define what "high quality" actually means and document it

- Train program authors to make better decisions

- Handle appeals and investigations

- Build systems that work at 100k projects/year

You'll still do plenty of hands-on review — you can't spot-check effectively without understanding the projects deeply. But your mission is ensuring the integrity of the entire process, not being the bottleneck for each submission.

$55-70k. 4 weeks PTO. Health/dental/vision. Based in an 1800s building in Shelburne, Vermont. Full details: https://hiring.hackclub.com/38523

Company name: Comper

URL to company home page: https://comper.io

Job positions available: Comper is seeking to expand their small team of 5 following a recent pre-seed raise. They are actively looking for multiple roles, specifically a Software Engineer and a Genius Designer (with ideal engineering prowess). The salary range for these positions is €80-100k plus equity.

About Comper & the roles: Comper aims to revolutionize how software landscapes are understood and explored, likening their ambition to "what Figma did to design" but for large organization codebases. Their core product is a revolutionary zoom-to-code UI canvas that integrates code, documentation, and diagrams with data overlays from git repositories. They leverage LLMs to analyze codebases and extract architectural insights, providing clarity during re-orgs, onboarding, or explaining tech stacks. The ideal candidates will be crucial in building this "revolutionary UI" and tackling complex problems to simplify software stack explanations. The founder & CTO emphasizes the need for serious thinking and pioneering spirit.

Technologies used: The platform utilizes LLMs (Large Language Models) to process codebase information. The product's core is a "zoomable canvas," indicating a strong focus on advanced UI/frontend development, though specific frameworks or languages are not explicitly mentioned.

Location: These are ONSITE positions located in Utrecht, The Netherlands.

Application process: Interested candidates should find the specific vacancies on the Comper website and then send an email to apply.

We make software landscapes understandable and explorable. Our canvas is zoom-to-code, and shows data on overlays from all of the git repos in your company. LLMs go through the codebase and extract the architecture.

We provide clarity when it's most needed: re-orgs, onboarding, explaining the tech stack at board meetings. Or just being stuck in your IDE and want to ask your team mate a question. We'd like to do to large org codebases what Figma did to design.

Comper needs someone that can build revolutionary UIs and go where no man has gone before. We are hiring a software engineer and a genius designer (with ideally some engineering prowess). Our UI is the core of our product: a zoomable canvas that has all your code, documentation and diagrams on it. We have a long way ahead and need serious thinking to make sure we explain the software stack as simple as can be.

I'm the founder & CTO. We just raised a pre-seed and are now with 5 people. Find the vacancies on our site and send us an email.

• Senior Site Reliability Engineers (SREs)
• Senior Cloud Security Engineers

• Data Scientists
• Data Engineers
• Mobile Engineers
• Backend Engineers (specializing in TypeScript)

Specifically, a Staff Data Engineer position is open for someone with the depth of experience to be a technical lead and mentor for the Data Platform team, while also actively shipping code. This role requires an intellectual, instinctive, and emotional understanding of distributed data systems, along with strong opinions about "the wild boar book" (a specific cultural reference from the poster). The salary range for these positions is not explicitly provided in the posting.

Technologies Used

The team utilizes AWS for their distributed systems. Specific roles require expertise in:

• TypeScript (for Backend Engineers)
• Python (for Data Engineers)
• SQL (for Data Engineers)

Work Location and Requirements

These are ONSITE / HYBRID roles, requiring 3 days per week in either NYC or Boston. Veho does not offer visa sponsorship for these positions.

Application Process

Applications should be submitted through Veho's career page. To ensure your application stands out and confirms you're a human, you are encouraged to include one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box. Additionally, please populate the "Location" field to confirm your awareness of the in-office requirement. All inbound applications are reviewed by humans.

Hi there! At Veho, we don't sell software. We ship packages. Lots of them. We have all of the interesting problems that crop up when running twinned distributed systems in AWS and the real world. It's pretty great.

We're hiring staff-level folks (L4+) in NYC and Boston: Data Scientists, Data Engineers, Mobile Engineers, and Backend Engineers (typescript).

Personally, I'm hiring a Staff Data Engineer with the depth of experience to be a technical lead and mentor for the Data Platform team, while also shipping code. You will need to understand distributed data systems both intellectually and at an instinctive, emotional level. You should have Opinions about the wild boar book. You should probably also be comfortable writing and debugging English, SQL, and Python.

If that sounds like you, I really want you to apply for the Staff Data Engineer role on our career page. Our inbound applications are reviewed by humans.

With apologies that our first interaction requires this silliness: including one of the 7-digit numbers from the "ROS Calculator" on Veho's website in the appropriate box will heavily bias me towards believing you are a human being. That's more of an advantage than it may seem! It's worth the thirty seconds. It would also speed things along if you populate the "Location" field to confirm you are aware this is an in-office role.
