• Strong Python skills; experience with PyTorch or Transformers; familiarity with the Hugging Face ecosystem.
• Practical knowledge of LLM tooling (e.g. LangChain or LangGraph) and RAG concepts.
• Experience building on AWS, ideally including:• Serverless functions (AWS Lambda) for orchestration,• Elastic compute (EC2) for workloads,• Foundation model services (Bedrock or SageMaker) for model hosting and tuning.
• Hands‑on with n8n; workflow automation experience is a plus.
• Containerisation with Docker; proficiency with Git and CI/CD.
• MLOps fundamentals: MLFlow for experiment/model tracking; evaluation frameworks (e.g. RAGAS).
• Clear communication, collaborative mindset and focus on shipping.
• Languages: strong English; German is a plus. Applications in English or German are welcome.
• Education: Degree in Computer Science or equivalent preferred; equivalent practical experience acceptable.

• Offsites with the team in exciting locations.
• Flexible working hours in a remote‑first company.
• Exciting product in a very dynamic market environment.
• Values‑based start‑up culture.
• Many opportunities to develop further and network with committed people.
• Flat hierarchy.
