About the role

  • Ramp Up: Become a domain expert in AMBOSS’s shop and payment architecture, from the purchase experience to international tax compliance.
  • Ship Impact: Deliver end-to-end features and improvements from discovery to deployment. That could be shipping a real product on shop or providing a localized, frictionless checkout experience for our global users.
  • Collaborate: Build deep working relationships with Product, Design, and Finance stakeholders.
  • Build & Iterate: Design and evolve high-availability services handling regional payment methods and subscription logic.
  • Own the Lifecycle: Manage discovery, technical design, deployment, and monitoring.
  • Innovate with AI: Use tools like Cursor or Copilot and research how emerging technologies (LLMs, automation) can add genuine user value.
  • Scale: Extend existing systems to support new markets and medical disciplines while maintaining clean integration with core infrastructure.

Requirements

  • Go (Golang): Strong backend fundamentals (concurrency, API design, error handling).
  • React & TypeScript: Solid foundations for building intuitive, responsive frontends.
  • API Design: Experience with GraphQL and/or REST.
  • Ops & Observability: Hands-on experience with Docker, CI/CD, and AWS/Kubernetes. You write your own tests and read your own dashboards.
  • Architectural Intuition: The ability to deconstruct complex codebases and (for Seniors) design data models at scale.
  • Product-Minded: You care about why we build, focusing on user impact and business value over technical complexity for its own sake.
  • Pragmatic: You know when to ship a quick proof-of-concept and when to invest in long-term stability.
  • AI-Native: You are comfortable with (and excited by) AI-assisted development.
  • Comfort with Ambiguity: You can make sound decisions even when requirements are still evolving.
  • Nice to Haves: Experience with Payment Providers (Stripe, Adyen, Braintree). Understanding of International Tax or fintech compliance. Exposure to Event-driven architectures or message queues. Previous work with LLM integration or AI-powered features.
