Senior AI Engineer – Berlin (On-Site)

(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.

• 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
  

mama health’s mission is to build the largest healthcare data platform where patient find answers and healthcare players see how they can improve. We built 2 products:

• a Patient App that helps chronic patients find answers to their daily questions - using best in class multi-agent systems and proprietary data
• a Patient Journey Analytics Platform to see real time patient needs, roadblock and what needs to be done to improve patients care

• Entrepreneurial spirit: We seek exceptional talent with the drive, passion, and creativity to shape the future of our company. This isn’t a place for those seeking routine tasks or detailed instructions. If you’re eager to influence the future of healthcare with your ideas and contributions, mama health is the place for you.
• Results-driven culture: We operate by objectives and reward exceptional performance. Goals are clear and accountability is key. If you miss your targets, we expect you to step up and put in the extra effort. When you achieve them, take the time to recharge and celebrate your success.
• Inclusive values: As a company addressing chronic diseases worldwide, we are building an international, diverse team. Our employees bring together a mix of medical, technical, and business expertise, representing over five nationalities.

At mama health, we work (very) hard but know how to have fun. Most of our team is based in Berlin, with regular trips to our Berlin office for remote team members. We offer a range of benefits, including educational courses, gym memberships, mentoring, and more. We host frequent team events and an annual "workation" where the entire team gathers for a week of collaboration and bonding.

Join us to help transform patient experiences into actionable insights and shape the future of healthcare.
