About the role

  • Support our team by developing and refining user interfaces for our cutting-edge IoT applications across various platforms, including web, mobile, and machine-embedded interfaces.
  • Implement pixel-perfect designs in Flutter.
  • Create intuitive and engaging user experiences that delight our customers.
  • Take on technical challenges in UI/UX optimization, performance enhancement, and cross-platform compatibility.
  • Assist with maintaining a high-quality codebase, ensuring scalable and maintainable solutions.
  • Collaborate closely with a small, dedicated team of 2–3 developers to drive the evolution of our IoT products.

Requirements

  • A solid technical foundation, either gained through a computer science degree, a completed apprenticeship, or a strong self-taught background with concrete, hands-on projects.
  • At least 2 years of practical programming experience; strong experience in another language can compensate for fewer years in Flutter specifically.
  • Good working knowledge of Flutter and Dart, including common state-management patterns such as Riverpod, Provider, Bloc, or MobX.
  • Experience integrating REST APIs and working with app-wide data/state flows.
  • Ability to build responsive, user-friendly UIs and a good understanding of mobile/UI/UX fundamentals.
  • Basic familiarity with testing and CI/CD workflows (e.g., GitHub Actions).
  • Strong verbal and written communication skills in English (German is a plus).
  • Experience with web frontends (e.g., Angular, Next.js).
  • Familiarity with Firebase, native mobile features, or Bluetooth/device connectivity.
  • Personal or side projects are a significant bonus, as they demonstrate genuine interest and give us insight into your practical experience.
