About the role

  • You will play an active role in migrating from Ember.js to React (React, Tailwind, TanStack Router, Capacitor.js)
  • Drive and maintain our Rails-based REST API (Rails, MySQL, Redis, Memcached, RSpec, …)
  • Design and implement new product features end-to-end
  • Continuously evaluate, improve, and refactor existing code
  • Contribute to architectural decisions and technical direction
  • Be part of the agile planning and delivery process

Requirements

  • 5+ years of experience with React and modern frontend development (state management, component architecture, hooks, performance, end-to-end testing)
  • Hands-on experience building production-ready React applications
  • Solid understanding of modern frontend tooling and ecosystems (TanStack Router, Tailwind, Vite/Webpack, REST APIs, etc.)
  • Professional experience with Ruby on Rails, including work on APIs and business logic (Rails, MySQL, Memcached, Redis, RSpec, GitHub, etc.)
  • Ability to design and implement complex features with non-trivial business requirements
  • Enthusiasm for AI technologies and hands-on experience with AI-powered tools to improve development workflows
  • Ability to communicate with remote and on-site teams
  • Native German speaker and fluent in English.
Benefits
  • Very few meetings, a non-hierarchical structure and no mandatory team events — which doesn’t mean we don’t enjoy meeting up and doing something fun ;)
  • Flexible working hours for our developers; all our processes are set up for remote work
  • Necessary hardware is provided — choose your preferred equipment
  • We enable the team to work in Cape Town once a year — maybe you’d like to escape the winter ;)
  • We live our mission and maintain a transparent and innovative company culture — something we as a team are very proud of
  • If you prefer coming to the office: our office is located in the heart of St. Pauli and is equipped with everything you need (drinks, fruit, coffee, table tennis, great view of the shipyards...)
  • Interested in further training? You’ll have our full support
  • Also: company pension contribution (BAV) & more ;)
  • Every two weeks we meet in the office for a team lunch
  • Once a month this includes our “Sparkle in Your Eye” session — an informal talk where one of us shares a topic they’re passionate about, work-related or not
  • We live our culture
  • A great working atmosphere, an open feedback culture and professional standards — the foundation of a successful company
  • Flexible working environment
  • Home office or hybrid work? No problem! Either way you’ll feel at home in our office — but you decide
  • Challenging problems to solve
  • We are growing and want to grow even more!
