We are working with a fast-growing AI-native startup in Berlin, looking for a Founding AI Engineer to own LLM workflow design, agent orchestration, and AI reliability in production. This is a specialist hire alongside the founding engineering team - you'll define how autonomous agents reason, act, and stay reliable at enterprise scale, working directly with the CTO from day one.
Required profile:
- Strong startup or scale-up experience, ideally at an AI-native product company (not a research lab)
- Hands-on experience shipping LLM-powered agents or workflows to real production users
- Proficient in both TypeScript and Python - backend and product-adjacent work
- Strong evals mindset - golden datasets, online metrics, tracing, regression detection
- Comfortable owning cost, latency, and reliability trade-offs at production scale
- Comfortable working in ambiguity and fast-moving founding-team environments
Required tools / stack exposure:
- Vercel AI SDK or equivalent modern AI stack
- OpenAI / Azure OpenAI, embeddings, vector stores
- Observability tooling such as Langfuse or similar
- Agent orchestration - tools, control flows, retries, safety checks, graceful degradation
- Next.js, workers, APIs
Required domain experience:
- Production LLM/AI systems is mandatory (academic or hobby-project AI experience is not sufficient)
Compensation: €80k – €130k base per annum + meaningful equity
