Technologies & Focus Areas

• AI‑native operating system for health plan administration
• AI agents automating high‑stakes operational workflows for TPAs
• Core platform infrastructure (backend, cloud services, data pipelines)
• Product‑centric engineering with strong code quality and reliability

About the Company

Korva is a self‑funded, pre‑seed health tech startup founded by UC Berkeley alumni with deep expertise in healthcare data, payer integrations, and provider workflows. It aims to rebuild the back‑office of 100M+ Americans covered by self‑funded health plans, replacing legacy software with AI‑driven automation.

Key Requirements

• 2–5 years of software engineering experience
• Clean, reliable coding skills and strong product instincts
• Comfort with ambiguity in an early‑stage environment
• Interest in healthcare or regulated industries is a plus (domain expertise not required immediately)
• Active use of AI in day‑to‑day engineering workflows

Korva is building the AI-native operating system for health plan administration. Self-funded health plans cover 100M+ Americans, yet third-party administrators (TPAs) run them on manual processes and legacy software. We're rebuilding that back office with AI agents that automate high-stakes operational workflows. Getting this right matters — millions of Americans' coverage depends on it.

Founded by UC Berkeley alums with deep experience in healthcare data, payer integrations, and provider workflows. Pre-seed, well-funded, NYC-based.

This is a broad founding engineer role: you'll design core platform infrastructure from scratch, build and ship AI agents for TPA operations, own systems end-to-end, and at times embed directly with customers to turn operational knowledge into product. You'll work closely with the founders and shape both the roadmap and the engineering culture.

We're looking for someone with 2–5 years of SWE experience who writes clean, reliable code, has strong product instincts, uses AI as a core part of their workflow, and is comfortable in the ambiguity of an early-stage company. Interest in healthcare or complex regulated industries is a plus—domain expertise not required on day one.

Job Position(s) Available

• Founding Backend Architect (Python/PostgreSQL)
• Salary: $150,000+ per year + benefits
• Location: Remote (US, EST hours) with a 1‑week paid onsite onboarding in New Jersey.
• Restrictions: Must be located in the US (EST hours); remote work only within the US.

Technologies Used

• Python, FastAPI, PostgreSQL
• Neo4j, Docker, Linux
• vLLM (local LLM inference)
• Microsoft Graph API (preferred)
• CRM migration experience (preferred)

Key Responsibilities & Requirements

• Design and deploy a complex PostgreSQL schema for freight operations across 30+ entities.
• Build Python service layers integrating multiple REST APIs.
• Wire locally‑hosted LLM inference into business workflows.
• Structure document ingestion, email processing, and asynchronous event‑driven pipelines.
• Define backend patterns for reliability and maintainability in a multi‑million‑record environment.
• Focus on system architecture, not individual feature implementation.
• First technical hire, reporting directly to the owner.

Application Process

Send a resume, a brief write‑up of an end‑to‑end system you designed (architecture decisions, not code), and a short note on why this role interests you to [email protected].

Additional Information

• Equity conversation open once a mutual fit is established.
• Self‑hosted stack: no cloud dependencies, no monthly GPU bills, no vendor lock‑in.
• Owner will be heavily involved in daily collaboration and architectural decisions.

We're a freight brokerage in NJ building a self-hosted, AI-first platform to replace our legacy CRM/TMS.

The AI compute infrastructure and data foundation are already in place. We need the architect who turns it into a production operating system.

This is a systems architecture role, not a feature dev role. If your primary strength is writing features or following tickets, this is not the role.

You will be responsible for: designing and deploying a PostgreSQL schema for complex freight operations across 30+ entities. Building Python service layers integrating multiple REST APIs. Wiring locally-hosted LLM inference into business workflows. Structuring systems that involve document ingestion, email processing, and asynchronous event-driven pipelines. Defining backend patterns for reliability and maintainability across a multi-million record environment.

The entire stack is self-hosted on custom-built server hardware. Database, application layer, AI inference — all of it. No cloud dependencies. No API rate limits. No monthly GPU bills. No vendor lock-in. You have direct access to the metal, you deploy on your terms, and the only ceiling on what you can run is the hardware itself.

If you've ever wanted to build a production platform without a cloud provider standing between you and your infrastructure, this is that role.

You are the first technical hire. You report directly to the owner, who is directly involved in this hire and in daily collaboration on the build. Architectural decisions are yours to make. AI coding tools and low-code UI frameworks are part of the workflow — your time goes to data models, service orchestration, and API plumbing, not hand-building screens.

Stack: Python, PostgreSQL, FastAPI, Docker, Neo4j, Linux, vLLM. Preferred: freight/TMS domain, Microsoft Graph API, CRM migration experience.

1-week paid onsite onboarding in NJ, then fully remote. Equity conversation open once mutual fit is established.

To apply, send: (1) your resume, (2) a brief writeup of a system you designed end-to-end — not code, but the architecture decisions you made and why, (3) a short note on why this role interests you.

Hands-on role — you're the person keeping production reliable and making it better.

Additional Requirements

• Technical leadership with proven ability to translate vision into architecture, build plans, and delivered products.
• Experience leading from a small core team (4 people) and managing at least one direct report.
• Familiarity with multi‑agent AI platforms and the stack listed above.
• Proactive, tool‑driven mindset; not just an executor but a strategic executor.

Equity & Funding

Equity is unencumbered; the company is profitable with no VC funding.

We're a profitable B2B services company ($3M–$50M ARR clients) actively building a proprietary AI platform — and we need the technical leader to own the execution.

WHAT WE'RE BUILDING: A multi-agent AI platform that operationalizes our founder-story methodology into deployable client systems. Architecture spec exists, pieces are already in production. We're not starting from scratch — we're scaling a real build.

THE STACK: LLMs (Claude, GPT, Gemini), multi-agent orchestration (LangGraph/LangChain), RAG pipelines, vector databases, React/Next.js, Python/Node.js, AWS, n8n/Make for automation.

WHAT MATTERS MOST: You're not just an executor. You come to the leadership table with tools and approaches we haven't seen yet. You translate the CEO's vision into a technical spec, a build plan, and a shipped product — without needing everything pre-defined.

THE TEAM: 4 core people. You'd join the CEO, a Growth Strategist, and an Operations Manager — and lead one AI Engineer (your first direct report).

ENGAGEMENT: Starts fractional with a clear path to full-time and equity for the right fit. We're not VC-funded by design, so equity is unencumbered.

• Interest in healthcare, data, and real‑world impact

Why This Opportunity Is Interesting

• Building a greenfield system that captures longitudinal data for eye care
• Access to clinical workflows, real patient data, and the largest smartphone eye‑image dataset
• Small, high‑ownership team with direct impact on patient outcomes

Most AI in healthcare is being built in the wrong place.

Everyone is chasing scribes and diagnostics. Almost no one is building the longitudinal data layer, the system that captures what actually happens to patients over time.

That’s the real moat. We’re building it for eye care.

Deya is an AI platform that sits between doctor and patient, capturing symptoms, treatments, outcomes, and ocular images over time to enable continuous care.

We’re already piloting with eye doctors and collecting real patient data, including the largest dataset of eye images captured on smartphones.

What you’ll do:

- Build core product + infrastructure from 0→1

- Work across full stack, AI systems (LLMs + vision), and data pipelines

- Help define the architecture of a longitudinal healthcare data layer

Who you are:

- Full-stack engineer (backend / full stack; AI experience a plus)

- Wants ownership and to build from first principles

- Interested in healthcare, data, and real-world impact

Why this is interesting:

- Greenfield system with real-world data + distribution

- Direct access to clinical workflows and outcomes

- Small, high-ownership team

NYC-based, Hybrid.

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

About the Role

You’ll be the first engineer on a startup that builds AI agents to automate the entire integration lifecycle: gather requirements in plain English, write the integration code, test, deploy, and self‑repair when it breaks. With paying enterprise customers and a backlog that can’t be kept up with, you’ll architect agent orchestration, a durable execution runtime, self‑healing infrastructure, and set many foundational decisions.

Company Background

The founders previously launched a logistics startup from pre‑seed to 400+ employees, gaining deep experience solving broken integration problems. Temper now offers an AI‑powered solution for the same domain, with growing demand from enterprise customers.

We built AI agents that do the whole thing: gather requirements in plain English, write the integration code, test it, deploy it, fix it when it breaks.

We have paying enterprise customers and more demand than we can keep up with.

Job Positions Available

• Software Engineer – ML/AI Infrastructure & Agent Orchestration
• Full-time, in-person in New York City
• Salary: $300,000–$400,000 base + discretionary cash bonus (irrespective of project outcome)

Technologies Used

Production‑grade machine learning and AI infrastructure, automated data analysis pipelines, agent orchestration frameworks, and cutting‑edge software tools for quantitative research. Specific language and platform requirements are not listed; the role is focused on high‑skill, high‑energy engineering and rapid learning.

Location & Work Arrangement

In‑person, New York City. Remote or hybrid options not offered.

Application Details

Send résumé to [email protected]. Start ASAP.

Additional Notes

• Project is a high‑risk, high‑reward R&D initiative; if it fails to show progress within 12 months it will be wound up, but compensation remains guaranteed.
• Opportunity to build an entirely new automated investment analysis system from scratch for a long‑standing, Buffett‑style investment firm.
• Ideal candidate: deep experience in ML/AI infrastructure, automated data analysis, and agent orchestration; high capacity to learn and adapt to evolving tech.
• No mention of sponsorship, visa support, or other restrictions.

Compensation: $400+k total (base + guaranteed bonus), all cash. We will pay more for the right person.

We are looking for a very high skill and high energy software engineer who is familiar with production grade data+ML/AI infrastructure and automated data analysis, and who is interested in agent orchestration.

We are building a new system entirely from scratch that applies LLMs and multi-agent architectures to a problem that has never been successfully systematized. This is an R&D project - something we have never done before in 30 years of trading - to launch a completely new automated investment analysis system within an extremely fundamental/qualitative/Buffett-like investment framework.

The initial team will be 3 people – including you. You will be responsible for all software engineering. This is a very high leverage and high responsibility role, with huge capacity for personal development and role expansion.

We are doing this with huge rigor, energy, and substantial financial backing. You will be the founding engineer. You will design and build the system from scratch, i.e., the architecture, the infrastructure, the agent orchestration, the evaluation framework, everything. There is no existing codebase, no legacy system, no committee.

We are looking for someone who has been building with, or at least seriously thinking about, LLMs and multi-agent systems for the past 12+ months. You will have thought deeply about failure modes, evaluation, and context management. You will probably have tried multiple orchestration frameworks and found them all inadequate in different ways.

You need to be a seriously rigorous SWE. You should be comfortable setting up cloud infrastructure from zero and building production-grade systems, not just prototypes.

If this works, it and you become a core part of a $20bn fund. If it doesn't show sufficient promise after 12 months, the project winds down. You will be paid in full either way.

We are Baseten, the team that powers mission-critical inference for the world’s most dynamic AI companies such as Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma and Writer. We’re growing quickly and recently raised our $300M Series E, backed by investors including BOND, IVP, Spark Capital, Greylock and Conviction.

Apply Here: https://jobs.ashbyhq.com/baseten?utm_source=gkzEP29VD4 or email [email protected]

We are hiring for multiple core roles:

1. Solution Architect: You will partner closely with sales and customers to translate business needs into technical solutions, run technical discovery, and guide repeatable deployments and proofs of value for customers. This role is a great fit for entrepreneurial, customer-facing technical professionals who want a front-row view into how modern companies adopt AI at scale, and who enjoy working across technical discovery, solution design, demos, deployment scoping, and hands-on customer implementations, in close partnerships with Sales and Engineering

2. AI Solutions Engineer/Forward Deployed Engineer: You will partner directly with customers to architect, build, and deploy high-scale production AI applications on Baseten’s platform. You’ll own the journey with customers from initial exploration to production deployment.

You'll triage and resolve issues across Kubernetes, GPUs, networking, and model serving, lead war rooms during P0 escalations, and translate recurring pain points into product improvements.

The Offer:

Compensation: Very competitive, we’re looking for folks with a breadth of experience

Equity: This is an opportunity to participate in the ownership of a fast-growing AI Infrastructure platform

Location: We are based out of San Francisco with offices in New York. We are also open to remote employees for these roles.

I am building a real-time fantasy soccer platform launching June 10th with the World Cup.

I have an open source scoring engine as the base. I need a backend engineer to adapt it to our custom rules and integrate it with our live data feed.

This is a flat-fee contract — $3,000–$4,500 for a defined deliverable. Paid in two tranches. Front-loaded work, most of it done in the first 30 days. U.S.-based, 1099.

What I am looking for: — Comfortable working inside an existing open source codebase — Node.js background — Understands event-driven architecture — Enough soccer knowledge to sanity-check scoring logic — U.S.-based with a legal entity to receive 1099 payments

If this is you: send me a link to one open source project you have worked with and two sentences on your Node.js background. Email: [email protected]

343 game|QA & Backend Engineer|Remote(US)|contract

I am building a real-time fantasy soccer platform launching June 10th with the World Cup. Development team is in Eastern Europe and moving fast. I need a U.S.-based QA and backend engineer on a paid contract to supervise daily execution through launch.

This is not a full-time role. It is a 70-day paid contract on 1099 — $4,000–$6,000/month depending on experience. Milestone-linked. If everything goes well there is a longer conversation after launch.

What I am looking for: — Shipped at least one consumer product end-to-end — Managed or supervised a distributed or outsourced team — Backend engineering background, mobile experience a plus — U.S.-based with a legal entity to receive 1099 payments — Available to start this week

If this is you or you know someone: send me two sentences about the last product you shipped. Email: [email protected].

No recruiters please.

Information Needed

Please provide the text of the job posting (or a link to it) that you would like summarized. Once I have the details, I can generate the requested HTML summary for you.

We are MiLaboratories, the team behind Platforma.bio & MiXCR. We are building the "OS for Biology"—the foundational infrastructure where all biological data is transformed into life-saving breakthroughs. We work fully on-site in Bilbao because the complexity of our problems (high-performance computing + deep biological nuances) requires high-bandwidth, in-person collaboration.

We dissolved traditional departmental silos. We are hiring hardcore builders, not analysts, for a critical core role:

*Senior TypeScript (SDK & Platform):* You will architect our frictionless, AI-native SDK to scale our ecosystem. This is not a CRUD web dashboard. You will build a heavy local desktop application that bridges directly with a high-performance Rust data layer. You must treat the browser engine as a runtime for heavy local apps. The standard is simple: if the SDK is too messy for us to build blocks at AI-speed, it is too messy for the world.

The Offer: * Comp: Top-tier EU salaries (€90k - €120k EUR). * Tax Advantage: Bizkaia has independent tax autonomy. You qualify for the "Special Impatriate Regime" (30% salary tax exemption + expense deductions - up to 50% in total). * The Reality: Your effective tax rate drops to ~15-20%, yielding a significantly higher net income than London or Berlin. * Stock: We grant ESOP and treat equity as a life-changing wealth vehicle, not a "nice to have." * Relocation: Comprehensive "Soft Landing" package (Visa, temporary housing, school search). * Location: Bilbao is a hidden gem—ocean, mountains, and high quality of life with a low cost of living.

Process: No HR screening. You will talk directly to the engineering team.

How to Apply

Apply via the Airtable form: Application Form (use this link rather than the email in the formal post).

Spade is a Series A startup building a wide range of products for the dairy industry.

Think apps for farm data, machine vision for cows and next generation embedded microchips for animal health data (its not evil I promise).

We are building tools with data and AI to create Superhuman Management for both the supply chain ( we have a enterprise suite for the companies that buy and process milk ) and farms.

Our customers are the biggest food companies and biggest dairy farms on the planet.

We are looking for people who love agentic coding, are willing to own whole applications, and want to work with an application that works with real-world data from real-world farms.

Never heard of a Ralph loop? NGMI...

Our best developers have < 2 hrs of meetings a week, we aim to make that 1 hr.

We want to push the limits of what what low bureaucracy, high autonomy building can look like.

We have up to quarterly in person meetups depending on your location.

Good pay and benefits obviously.

Build is a full-stack cloud platform — we own the stack from bare metal up. Our customers are engineering-led SaaS teams who've outgrown their current setup and want effortless deployment, real environments, and predictable pricing without the infrastructure overhead. Think teams escaping from Heroku, scaling past Vercel/Fly.io, or trying to escape AWS/GCP/Azure complexity.

We're hiring our first Technical Account Executive. This is a full-cycle role — you'll own outreach, discovery, and demos through to close, partnering closely with the VP Sales.

We're looking for someone with 4–7 years in devtools or cloud infra space who can hold a real conversation with engineers and understand what's actually broken in their setup. A background in cloud/devtools sales or Solutions Engineering but ready to own the whole cycle are both strong fits.

Job Position

Software Engineer – Full‑time, Hybrid (on‑site in Delft, Netherlands)

Salary range not disclosed.

Technologies

• React & TypeScript (full‑stack)
• Python (backend)

Key Details

• Hybrid work model: on‑site in Delft with flexible remote days.
• Open to candidates with a willingness to learn; no specific skill set required.
• Apply directly via the link provided above.

At Formical, we believe we can become the first sustainable generation on Earth. Biotechnology plays a key role in this future - benefiting all people, animals, and our planet by making industrial production more sustainable. But bioprocessing still runs on fragmented data and tacit knowledge. The infrastructure to turn data into the intelligence that teams need to scale doesn't exist yet, hindering the sector’s progress. Our product accelerates bioprocessing by connecting fragmented data, enabling predictive modeling, and ultimately closing the loop between measurement and action.

We're not looking for specific skills, just willingness to learn. I joined a couple months ago with little React/TypeScript full-stack experience, but with CC I managed quite well coming from a Python backend background. Nothing's enforced though! We're a small team, have some customers, and are looking to build out the platform and the client-base significantly this year.
