Your mission (This role requires you to be based in Berlin) As a Senior AI Engineer at mama health, you will build and own the core AI systems powering our product — from patient-facing experiences to our Pharma Platform. You will: Design and ship production-grade AI systems: Build scalable LLM-based systems, including workflow agents and multi-agent architectures, that run reliably in real-world environments. Own AI features end-to-end: Take responsibility from idea → prototype → evaluation → production, with a strong focus on quality, reliability, and impact. Build robust RAG pipelines: Implement retrieval systems using embeddings, vector databases, and structured data to ensure grounded, high-quality outputs. Develop intelligent patient-facing features: Create systems that turn unstructured patient data into personalized insights and health reports. Drive evaluation and quality: Build and iterate on evaluation frameworks for LLM outputs, retrieval quality, and agent performance. Collaborate cross-functionally: Work closely with product, data, and domain experts to translate real healthcare problems into effective AI solutions. Optimize for performance and scale: Improve latency, cost-efficiency, and robustness of AI systems in production. Your profile Bachelor's or Master's degree in Computer Science, Data Science, or a related field Strong experience building LLM-based applications in production Excellent Python skills Hands-on experience with: RAG systems, embeddings, and vector databases Prompt engineering and structured outputs At least one major LLM framework (e.g. LangChain, LangGraph, LlamaIndex) Experience with agent-based systems (e.g. Autogen, CrewAI, or similar) Solid engineering fundamentals: clean code, testing, CI/CD, Docker Experience with LLM evaluation or search quality is a strong plus Familiarity with AWS, GCP, or Azure You are execution-focused and pragmatic — you ship and iterate quickly You’re comfortable working in ambiguity and fast-paced environments About us mama health’s mission is to build the largest healthcare data platform where patient find answers and healthcare players see how they can improve.
