We're working with an ambitious, well-backed AI startup building software that helps businesses automate complex, content-heavy workflows. With strong early traction, they're expanding their product and engineering team and looking for an engineer who wants to make a real impact.

This is a high-ownership role combining Python backend engineering, distributed systems and full-stack product development. You'll build and scale production systems, working across Python/Django and TypeScript/React.

What you'll be doing

Building reliable, high-throughput Python services and asynchronous workflows.

Tackling distributed systems challenges across performance, scalability and reliability.

Contributing to the React/TypeScript frontend and developing across the stack.

Owning features end to end, from technical design through to testing and release.

Using AI-assisted development tools and specialised agents to improve productivity without compromising engineering quality.

What they're looking for





Strong Python experience building and operating production systems.

Django experience strongly preferred, alongside distributed systems knowledge.

An interest in full-stack development. React/TypeScript experience is a bonus, but willingness to learn is essential.

Strong ownership, proactive problem-solving and sound engineering judgement.

An interest in AI-assisted development, with the ability to review, test and take responsibility for the code that ships.

You'll have the opportunity to influence architecture, shape engineering practices and help build a growing AI product. Engineers own their work end to end, use structured agent-assisted workflows and are encouraged to challenge ideas and improve how the team operates.

Fully remote across CET time zones, with €80k–€120k plus equity.
