Background

Join Next Level Coffee, the trailblazers behind nunc., our cutting-edge IoT coffee ecosystem. We're on a mission to revolutionize home coffee experiences with our premium products—coffee machine, grinder, app, and more. Launching in 2025, nunc. combines innovation and convenience for coffee lovers everywhere. With strong financial backing and a dynamic team, we're poised for rapid growth. Ready to transform the way the world enjoys coffee? Join us!

So what is the role?

You 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.

  • Your daily tasks include implementing pixel-perfect designs in Flutter.
  • You are responsible for creating intuitive and engaging user experiences that delight our customers.
  • You take on technical challenges in UI/UX optimization, performance enhancement, and cross-platform compatibility.
  • In the area of feature implementation, you assist with maintaining a high-quality codebase, ensuring scalable and maintainable solutions.
  • You collaborate closely with a small, dedicated team of 2–3 developers to drive the evolution of our IoT products.

This is the next level you achieve after 6 months:

  • You have delivered key features for the IoT machine, the grinder, and the web app interfaces.
  • You take ownership of medium-sized features end to end, from clarifying requirements to shipping to production and maintaining them afterwards.
  • You write code that fits our patterns and needs only minimal adjustment during review.
  • You’ve helped improve either test coverage, code quality, or both.
  • You can independently debug issues across Flutter, backend integrations, and app state management.
  • You have a measurable impact on app quality and maintainability: fewer regressions, better performance, more stable UI behavior, and faster iteration on UI changes.

What you need for this role:

  • A solid technical foundation, whether 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.

What we deliver on:

  • We want to do great stuff with a great team – this only works with a #nofilter and #nobullshitattitude.
  • Huge opportunity to join early stage and build a company – you work on our common vision, product and values!
  • You are best in class – and are enabled to make best in class decisions.
  • We love working visually and with the end result in mind, then get there by building fast and learning fast.
  • We love humans, we love coffee and working with the coffee community, from farm to cup.
  • Hybrid working – you work remotely, but once a month we meet for 2–4 days in Konstanz, the Alps, or Mallorca.
  • Your home office setup tailored to your workday needs.
  • Fitness programs, childcare subsidies, a home coffee supply, and many more benefits await you.
