Senior Software Engineer (m/w/d)

You'll be a core contributor to the Admin Experience team.

• Design and develop secure, well-tested features across a TypeScript/Node.js backend and React frontend
• Contribute to our API-first infrastructure — the engine behind how partners integrate insurance into their products
• Build AI-powered features using Claude and Gemini — from intelligent claims automation to LLM-assisted OPS tooling we run in production today
• Design and implement agentic workflows — multi-step, LLM-orchestrated processes that replace manual ops tasks across claims, support, and partner onboarding
• Work across the full stack with PostgreSQL, Redis, DocumentDB, Kafka, and AWS
• Collaborate closely with Product, Platform Engineering, Finance, and Operations to turn business requirements into reliable, maintainable solutions
• Drive technical improvements in quality, performance, and security — your initiative is welcome, not just tolerated We operate in a regulated environment (BaFin, DORA, EU compliance), so thoughtfulness about security and data integrity — including when AI is in the loop — is part of the job.

You don't need to tick every box. If this sounds like your kind of work, we want to hear from you.

• 5+ years as a Software Engineer — we care about the quality of your experience, not just the length
• Very strong command of TypeScript / JavaScript and Node.js; familiarity with React is a plus
• Hands-on experience with LLM APIs (Anthropic, OpenAI, Google, or similar) — you've built something real with them, not just experimented
• Familiarity with AI-native development patterns: prompt engineering, RAG pipelines, tool/function calling, agentic orchestration, or MCP
• Comfort reasoning about AI reliability and risk in production — output validation, fallback strategies, observability of LLM-driven flows
• Hands-on experience with databases like PostgreSQL, Redis, or DocumentDB; event-driven systems (Kafka or similar) are a bonus
• Comfort working in AWS environments with Docker and CI/CD pipelines
• Solid understanding of DDD, SOLID principles, and modern system design
• Experience writing unit, integration, and contract tests — including how to test non-deterministic AI components
• Experience in fintech, insurtech, payments, or banking integrations — or genuine curiosity to learn the domain
• Clear communicator who can hold a technical discussion and a product conversation in the same meeting Fluent in English — German or other languages are a plus
