AI Engineer for LLM Ops & Evaluation (m/f/d)

You'll join an early-stage, AI-native startup with a product that has already proven market fit. We build cutting-edge AI solutions for Governance, Risk and Compliance (GRC) for enterprises around the world.

Our customers are auditors, risk managers, and compliance teams, which means evaluation rigor, auditability, and EU AI Act readiness aren't afterthoughts for us. They're product requirements.

Tasks

As our AI Engineer for LLMOps & Evaluation, you'll own the LLMOps pipeline end-to-end and work directly alongside our founding team.

You will:

• Own the LLMOps pipeline: Evaluate infrastructure, prompt optimization loop, and the production integration that turns experiments into reliable customer-facing features
• Design evaluation strategy per output type: Decide when to use deterministic evals (exact match, schema validation, embeddings) vs. LLM-as-judge, and build the rubrics, test datasets, and human-review loops that make the system trustworthy
• Drive prompt engineering and optimization across all LLM operations in the product: Moving from hand-tuned prompts to a measurable, iterative process
• Pick the right tool for each problem: Some things are LLM problems, some are embedding + classical NLP problems, some are deterministic logic
• Run the production side of AI features: Observability (Langfuse /LangSmith / similar), cost and latency engineering, incident response when an LLM feature degrades
• Build human-in-the-loop workflows: Review queues, feedback ingestion, labeling; so production signal feeds back into evals and prompt iteration
• Mentor our AI & Analytics Intern and contribute to how we build the AI team over time

Requirements

• 3+ years of hands-on experience building and shipping ML/AI systems in production (we care more about what you've shipped than years on a CV)
• Have shipped an LLM evaluation or prompt optimization pipeline, not just used LLMs in a project, but owned the loop
• Strong hands-on experience with LLM-as-judge, including its variance problems and concrete techniques for controlling them
• Solid foundation in classical NLP and ML ops: Embeddings, semantic similarity, entity matching, classification, fuzzy matching
• Informed opinions on deterministic vs. LLM-based evals, from experience
• Production judgment: You've owned cost and latency tradeoffs, observability, and incident response for an LLM-powered feature. You're familiar with prompt regression and have strategies for managing it
• Strong Python
• Excellent English communication, written and verbal: We discuss nuanced technical tradeoffs daily with the founding team and customers
• Comfort with ambiguity: You can run experiments on real data, build intuition for this domain, and know when to stop iterating

Nice to have

• Hands-on experience with LLM observability and eval tooling (Langfuse, LangSmith, Phoenix/Arize, Helicone, Braintrust, W&B)
• Experience with DSPy or similar prompt optimization frameworks, and opinions on where they do and don't work
• Experience with Azure OpenAI in EU regions, or with EU-sovereign providers (Mistral, Aleph Alpha)
• Exposure to guardrails, content safety, or AI governance
• Exposure to enterprise software, ideally GRC, compliance, audit, or regulated industries
• Familiarity with Java/Spring Boot or Kubernetes on Azure; enough to integrate cleanly
• German

Benefits

• Hands-on ownership of a real AI product used by enterprise customers
• Work directly alongside the founding team from day one
• Hybrid work model: Munich North, minimum one day per week in the office, otherwise flexible (open to strong candidates elsewhere in the EU for the right fit); onboarding will take in-office
• A steep learning curve at the intersection of LLM engineering, enterprise GRC, and startup operations
• The chance to shape the AI team as we grow
