Job Technologies
Your role in the team
- 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.

Our expectations of you
Qualifications
- Sehr gute Kenntnisse in TypeScript / JavaScript und Node.js; Erfahrung mit React ist von Vorteil.
- Vertrautheit mit AI-native Entwicklungsmustern: Prompt Engineering, RAG-Pipelines, Tool/Function Calling, agentische Orchestrierung oder MCP.
- Comfort reasoning about AI reliability and risk in production - output validation, fallback strategies, observability of LLM-driven flows.
- Comfort working in AWS environments with Docker and CI/CD pipelines.
- Solid understanding of DDD, SOLID principles, and modern system design.
- Clear communicator who can hold a technical discussion and a product conversation in the same meeting.

Experience
- 5+ years as a Software Engineer - we care about the quality of your experience, not just the length.
- Hands-on experience with LLM APIs (Anthropic, OpenAI, Google, or similar) - you've built something real with them, not just experimented.
- Hands-on experience with databases like PostgreSQL, Redis, or DocumentDB; event-driven systems (Kafka or similar) are a bonus.
- 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.
