(Senior) AI Product Engineer (m/w/d)

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
