🌐 Full Stack Developer — Automating AI Workflows in Insurance

Summary

We’re building end-to-end automation for AI tasks in the insurance sector. Over the next 10 months, we’ll be prototyping before launching a dedicated spinout. You’ll work closely with our Senior AI CTO (30+ years of combined AI experience across the team) in a fast-paced but supportive environment.

This is a full-time, remote-first role (office available in Berlin). You’ll be expected to make strong use of AI tools to accelerate development and — even more importantly — debug efficiently. Success in this role requires both technical ability and a willingness to dive into the business logic of how insurance actually works.

What You’ll Do

• Develop and maintain backend services in TypeScript, using frameworks like Mastra, AWS Lambda, and Next.js
• Prototype and ship features that automate complex insurance processes
• Work with the CTO on model integration (potentially fine-tuning later in the roadmap)
• Debug and optimize workflows using AI tools for rapid iteration
• Build a deep understanding of insurance workflows to translate domain needs into technical solutions

What We’re Looking For

• Strong experience with TypeScript and modern frameworks (Next.js, serverless/Lambda)
• Ability to quickly learn and apply new tools like Mastra for workflow automation
• Comfort using AI coding assistants — not just to write code, but to debug effectively
• Curiosity to understand business logic in insurance and apply it to product design
• Availability for full-time commitment in a distributed, remote-first team (EU time zones preferred)
• Fluency in English or German

Nice to Have

• Experience with AI model integration or fine-tuning
• Background in automation, workflow orchestration, or backend-heavy applications
• Previous exposure to insurance, fintech, or other regulated industries
• Open-source contributions (any scale — show us what you’ve built!)
• If you speak German, it would be much easier to integrate into the team.
