About the role

  • Full-stack development: You will work on our TypeScript/Next.js application and the Supabase backend.
  • DevSecOps & infrastructure: You build and maintain stable, secure, and automated CI/CD pipelines and deployments on Vercel and Supabase.
  • Security first: You think in threat models, hardening, auditability, and logging.
  • Code quality & architecture: You conduct code reviews, establish best practices within the development team, and ensure a clean, robust, and scalable codebase.
  • Mentoring & sparring: You act as a technical sparring partner for Kai and help the team grow with your experience.

Requirements

  • Several years of professional experience in software development, ideally focused on TypeScript, React/Next.js, Node.js, and DevOps.
  • Deep understanding of modern web architectures, API design, and deployment automation.
  • Experience with cloud infrastructure, monitoring (e.g., Sentry), security, and CI/CD.
  • You are pragmatic, independent, self-driven, and hands-on — and want to build a product that lasts.
  • Bonus: Initial experience with blockchain technologies or EVM smart contracts (not required).
Benefits
  • A meaningful project with ownership: You work on our product, not on client projects.
  • VSOP participation: You directly benefit from the success you help build.
  • Short decision paths, real responsibility: No management madness — you make your own decisions.
  • A strong team: Fast, competent, loyal, and motivated.
  • Flexible working: Remote, hybrid, or at our modern office at the Old Slaughterhouse in Karlsruhe.
