Tech Lead AI Engineering (m/w/d)

For a young company in the rapidly growing AI implementation market, we are looking for a Tech Lead, starting as soon as possible, ideally in early November. The company runs LLM-based systems in production: content generation pipelines, retrieval-augmented generation (RAG) on internal documents, and automated workflows closely integrated with their business systems. The entire stack is built on TypeScript and Next.js.

These systems are already live. As Tech Lead, you take ownership of them, increase their reliability and quality, and expand them to new use cases, while being technically responsible for a team. The role brings together applied LLM engineering and solid backend engineering in TypeScript. Training or fine-tuning foundation models is not part of the job.

Stack: TypeScript, Next.js, Node.js, Postgres with pgvector, Docker, Azure, Anthropic and OpenAI APIs, Vercel AI SDK.

• Hybrid setup with 2 office days per week in a bright office in Cologne’s Belgian Quarter (with two balconies and the best view of the city ;))

• AI implementation, the growth market of the coming years

• Trust-based working hours with compensation for overtime

• Lots of creative freedom and space for your own ideas

• Continuous professional, strategic and technological development

• An open feedback culture, transparent communication and short decision-making paths

• Regular team events and workations

• Salary from €60,000 gross per year, with room for more depending on experience

The company is an international team and is actively committed to an inclusive workplace. Applications from people of every gender and identity are welcome, regardless of origin, age, religion, sexual orientation or disability. As women remain underrepresented in tech, women are especially encouraged to apply.

We look forward to receiving your application!
