Careers at FlowSIM Pro
We're always looking for talented students who are passionate about programming and want to work on challenging simulation software.
No fear of C++? Perfect. We develop professional desktop applications with C++ and Qt. If you enjoy solving complex problems and writing efficient code, you'll fit right in.
Open Positions
Working Student - Software Development (m/f/d)
Join our development team and help us build the next generation of building simulation software. You'll work on real features that users around the world rely on.
What you'll do:

- Curiosity about simulation, physics, or 3D graphics is a plus
- Business-level German proficiency in reading and writing (required)
Internship - Software Engineering (m/f/d)
We're a small, hands on team, not a training academy. You'll learn by doing: exploring real codebases, implementing features, fixing bugs, and shipping improvements that users actually see. We won't teach you textbook C++, but you'll get meaningful tasks, direct feedback, and exposure to modern tools, including AI assisted development workflows that are reshaping how software gets built. If you're curious, self driven, and want real responsibility over polished onboarding slides, you'll fit right in.
What you'll learn:
- Professional C++ development practices
- GUI development with the Qt framework
- Working with large codebases
- Software architecture and design patterns
