We began in 2017 as TimescaleDB, focused on making PostgreSQL the best database for time-series data. As our customers evolved, so did we.

Today, more than 2,000 companies use our technology to power real-time analytics, agentic applications, and high-ingest operational systems. What started as a time-series database has become the fastest PostgreSQL for modern workloads. To reflect that evolution, we’re now TigerData—a name that speaks to our speed, precision, and ambition. The tiger has long been part of our culture: fast, focused, powerful. From “Tiger Time” all-hands to welcoming new hires as “tiger cubs,” it’s how we build—decisively, fearlessly, and with purpose.

This is not a reinvention: it’s a reflection of how we already serve our customers today.

Background: px dynamics was founded by me less than half a year ago, I have 15 years experience in short term power trading in European markets, esp. algo trading. I do some consulting to bootstrap the company with and build customer relations. Simultaenously, we're starting to build a product business. For that we have strengthened the team with a Senior ML Engineer (ex google) and a Head of Data with prior experience in setting up data pipelines in this domain. The products we build are in a broad sense trading signals, e.g. to help traders of renewable or flexible assets trade their positions better.

Role: So given that it is pretty early days, we're of course looking for a broader skillset to lead the development especially of the cloud and backend infrastructure (hetzner), but eventually also frontend applications. Techstack so far is obviously minimal (linux, python, bash, postgres/timescale), so there is plenty of room to also shape this. What we as a team value is simplicity, really clean code/architectures, excellent documentations and quality over speed. So we're not trying to glue together the next venture to scam a bunch of VCs, but to really build something excellent.

if that resonates with you, please reach out to me directly via the email address you'll find on our website.

Stack: Python, Django, GraphQL, AWS, TypeScript, React, Terragrunt/OpenTofu

Ideal: early-stage experience, deep experience in healthcare integrations (FHIR, HL7, etc.), thrives solving problems

Hello everyone! I’m on the lookout for an SVP of AI & Tech Operations to join my team at Zeno Group. https://www.zenogroup.com

We're a global, integrated communications agency, and one of PR Week's Best Places To Work 2025!

• I’m shaping the technology landscape at Zeno from the ground up, which means juggling everything from procurement to infrastructure to education, and need someone who can help bring order to the chaos. We have a ton of amazing and passionate people and I (still!) only have two hands.

• What you'll do is wear many hats, and so adaptability is 100% your most important attribute, along with:

- Being a diplomat between Zeno and our sister companies

- Leading AI+technology education and literacy programs

- Performing discovery for and designing workflow automation

- Convincing creatives that AI won't steal their Cannes Lions

- Exploring turning random AI experiments into useful tools

- Keeping up with AI exploration and experimentation because it’s something you do already

• You need to be comfortable building with duct tape while executives ask why it's not done yet. Agency experience helps but isn't required; what matters is you can handle 72-hour deadlines, massive egos, and the phrase "the client changed their mind."

• You also don’t buy the hype, and can cut through tech industry bullshit like a hot knife through AI slop. Being a practical cynic is a strength—you want to believe.

• If you've successfully implemented some cool AI heat at scale and can explain it to people who still print emails, let's talk.

• Hybrid role, based in NYC. Big on cultural fit. While this is not a client-facing role, some occasional face time with clients is expected.

Here's the giant link to apply:

At Strum AI, we're reimagining technology that powers global supply chain using a fresh AI-first approach. Most supply chains are still stuck with Excel or enterprise tools that take months (and $MM) to adopt.

We’re on our journey to democratizing supply chain technology. As our first engineer, you’ll be working with the founders (former Supply chain/tech directors at Amazon who have built key components of Amazon's supply chain) to develop the core product from the grounds up (involves application of LLMs, deep learning, optimization, agents, simulations, and serious UX re-imagination). We're looking for folks who have held Principal/staff level Engineering roles in big tech or have built SaaS startups from 0->1 that have gone to raise Series B+ rounds.

We're mid-transformation: moving to autonomous teams, mob programming, whole-team product discovery. Looking for engineers who want to shape how a team works, not just write code.

Common Prefix is a science-first blockchain consulting company. Our vision is to make blockchains usable for mainstream users and everyday people – paying at the supermarket, remittances, moving money across borders, saving, investing – and solving the real problems of usability, scalability, and interoperability that come with it.

We're a 30-person team, half scientists (cryptographer PhDs, post-docs, and professors) from renowned universities, half engineers with long web2 experience. A lot of our field is broken and we're trying to make a small contribution in fixing it, by introducing provable security and proper engineering practices across the board.

What we're looking for: Software engineers who can solve problems, are smart, get things done, and enjoy working on the bleeding edge, learning about cryptography, and working from first-principles. Auditors who can write and read code, especially low-level cryptographic implementation code (zero knowledge verifiers, signature schemes, etc), consensus (PoW, PoS), or smart contracts (everything DeFi).

Tech stack: Doesn't matter, we'll teach you. But we work mostly with Rust.

* Auditor, https://commonprefix.notion.site/auditing-folk

We offer:

- $80,000–$160,000 / year cash

Phrasing is a language learning application optimized for learning and maintaining multiple languages, and designed to take you all the way to fluency and beyond. It the professional language learning application for serious learners.

It's built with Elixir on the backend, and ClojureScript on the front end. I did try to avoid such an esoteric tech stack, but functional programming and immutable data are just too good.

I'm looking for someone to come in and take over the Elixir backend for a few main reasons:

1. I long ago hit the limit of what one engineer can do

2. I need to focus on customer facing issues for the foreseeable future, and don't want progress to stop on the backend

3. I need someone to collaborate with, if not just to discuss technical details

I'm trying to do something different with Phrasing, on both a product and a company level. I'm personally tired of the rampant enshittification of the entire web, and miss the magic of the early internet. I'm trying to make a massive product, built by a tiny team of people doing the best work of their lives.

I've got a product and some extremely happy (paying users, but this is a very early stage startup. Anyone who joins now would be paid in revenue share (of which there is some) and equity, and should be willing to put in a lot of work and take a fair amount of risk. You need to be passionate about your craft, interested enough in language learning to dogfood the product, and crazy enough to believe you can change the world.

If you're interested, please send me a well written email to [email protected]. Low effort applications will be ignored. The first step of the interview process is a 60 minute interview, so if your application does not make me say "hell yes" then it will likely be rejected.
