Aleph Alpha is hiring a Senior Senior LLM Engineer — sovereign AI on the Foundation models team (Hybrid · Heidelberg, Germany). This is a hands-on role in LLM & generative AI—not a generic “AI enthusiast” post.
You will own LLM features, retrieval, agents, and evaluation end to end: problem framing, offline evaluation, safe rollout, and iteration from production signals. Success is measured with clear metrics (quality, latency, cost, or business KPIs)—not slide decks alone.

What you will do
- Ship production foundation models and LLM ops with offline evals, monitoring, and safe rollout.
- Work with product and domain experts on requirements and trade-offs.
- Improve data pipelines, labeling, and metrics tied to business KPIs.
- Document runbooks for on-call and customer-facing teams.
What we look for
- Strong Python and modern ML/LLM stack with shipped features.
- SQL, experimentation, and clear communication to stakeholders.
- Eligible to work in the listed country; professional English required.
