About the role

As an Application Engineer, you will develop industry-grade software which is used in more than 100+ countries around the world in coffee roasteries. You will be part of a development team that works on our standalone application called Roasting Intelligence (RI). The RI application connects many different roasting machine types from different vendors with our cloud application. It visualizes roasting parameters in real-time, incorporates machine learning algorithms for smarter roasting, and allows one to annotate roast metadata during and after the roasting process.

What you will do

  • Proactively participate in adding new features which empower our users to monitor and control coffee roasting machines - your work has a real impact on a large user base and improves the roasting processes every day!
  • Collaborate directly with product managers, designers, and developers in a small, cross-functional and agile team.
  • Enhance our internal knowledge base, e.g. by exchanging with hardware vendors, researching how to connect to different machines, collecting essential settings, and implementing new hardware integrations into our platform.
  • Help the support team and the developers in solving customer issues.
  • Build high-quality, clean, scalable, and reusable code by enforcing best practices around software engineering architecture and processes (Code Reviews, Unit testing, etc.).
  • Deliver production-ready solutions for real-world problems and take ownership over parts of the product.
  • Learn about the specialty coffee industry and have an impact on the livelihoods of tens of thousands of coffee producers.

Our technology stack

  • The backend is written in Java.
  • We use JavaFX for the visualization.
  • The application communicates via REST endpoints with our cloud-based backend (Java Spring).


We are looking for a person with

  • 3+ years of programming experience with at least one modern language such as Java, C++, or C# including object-oriented design.
  • A degree in Computer Science or a proven track record in developing non-trivial applications is a strong plus.
  • Comfortability coding in Java. Working understanding of software test automation.
  • A passion for solving real-world problems and writing reusable code that lasts for years, not months.
  • Ability to discuss with your team colleagues from product management, design, and development.
  • A strong command of written and spoken English.

That said, we'd be particularly delighted to hire someone with

  • Experience with JNI or JNA
  • Knowledge of networking basics

  • You can have a huge impact here.
  • We care about our people as much as we care about our customers. Work-life balance is not only a catchphrase for us and flex time and home office are a given.
  • Feedback equals growth for us. Welcoming and sharing insights help us grow personally and professionally.
  • People working in the coffee industry are passionate, open, inspiring, and just pure joy to work with. There are not many industries that can claim that.
  • Purpose. Our ❤ beats for coffee and its industry—from producer to barista—and our work has a lasting impact on it.

  • We grow and move at a steady pace and still learn new things as we go. If you’re reluctant to change and like things the way they are, we’re probably not a perfect match.
  • If the things mentioned in the why you might want to work with us section aren’t for you.
