Role
Who you are
- 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
What the job involves
- 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 take
Berlin-based Alteos develops tailor-made insurance solutions as ‘embedded insurance’ through innovative sales partnerships. It offers insurance-as-a-service and contains a wide portfolio of insurances, which are fully integrated and ready to purchase at the point of sale.
What sets Alteos apart is its unique technology platform, which was developed in-house and allows for better flexibility and efficiency. This has resulted in the company gaining over 100 million clients across the world, highlighting the success of its personalised approach to insurance solutions.
Alteos is a subsidiary of AXA Konzern AG, the French multinational insurance company. It therefore benefits from the experience and solidity that AXA brings when carrying out its task of simplifying and automating the insurance industry, which should put it in good stead to further its growth.
