  • Berlin


  • What You'll Do

    You’ll identify open AI opportunities, build them from start to finish, and bring them to real users. As a Senior AI Product Engineer, you’ll work across our three product squads: You’ll single-handedly turn unaddressed topics into products, hand them off once they’re up and running, and serve as a sparring partner for the squad PMs on all AI-related topics. For us, “senior” refers to your approach to work, not your years of experience. You’ll report directly to Product Leadership.

    Your Responsibilities

    • Independent AI projects (about half of your time)
    • You’ll identify high-impact AI opportunities in our legal workflows - in areas where no specific squad is responsible
    • Validation happens quickly: discussions with attorneys, Legal Ops, and insurers; prototypes built in days
    • You’ll bring the winning solutions into production yourself: routing, chaining, summarization, and agent-based loops
    • You’ll hand off mature features to the squad - complete with documentation, evaluations, and a handover plan
    Support for the squads (the other half)
    • Feasibility, costs, model selection, risks: You’ll answer these questions before every AI feature is launched
    • You support the teams in designing evaluations, golden datasets, and guardrails
    • You review concepts before they go into the roadmap - including prompt injection and compliance risks (GDPR, Section 203 of the German Criminal Code)
    • You advance AI best practices: prompt engineering standards, LLM observability, and agent-based coding workflows

    What you bring

    Must-have

    • Multiple production-ready AI/LLM systems that you’ve shipped to real users and taken responsibility for - no prototypes
    • Demonstrable product ownership: from a vague problem to a finished product
    • Strong Python skills and a solid foundation in software engineering (Git, testing, CI/CD, code review)
    • In-depth experience with LangGraph, LangChain, or similar - including an understanding of what’s happening under the hood
    • Proficiency with LLM provider APIs: function/tool calling, structured outputs, streaming
    • Evaluations, golden datasets, and guardrails before deployment
    • Solid prompt engineering - you know when to use which technique
    • Business-level English; German is a major plus due to our legal domain
    Soft Skills
    • The maturity to work without a squad around you: You set your own priorities and know when to say no
    • You can explain a technical trade-off to a lawyer and a legal workflow to an engineer
