Founding Engineer (ex-founder/CTO)

Most LLM apps break in production - you know this.

This role is about building the infrastructure that makes them reliable.

Astounding founding team, real ownership and solving hard distributed systems problems - the 3 hit combo.

You’ll be joining a leading AI platform used by hundreds of teams to build and monitor large-scale LLM applications.

Working directly with a small team across Germany and SF, you’ll own and scale the backend infrastructure powering terabytes of AI tracing data per day.

You'll build and optimise ingestion pipelines and make large-scale observability fast and affordable.

Your work will be open source, ship fast, and be used immediately by engineers running real AI systems in production.

Stack: TypeScript, React + modern data and LLM tooling.

High agency, strong backend fundamentals, and interest in data-intensive systems required.

Suitable for ex-founders, CTOs looking to go back to hands on engineering or wildly ambitious continuous learners who want an opportunity to build something special - not work life balance.

Salary up to $160k+. Open to exceptional remote people across Europe.

No CV required to start the chat, please apply and we can work through that later.

If you want to fast track your application, please message our founder Kieran directly.
