Java UI Developer

Siemens Digital Industries Software is a leading provider of solutions for the design, simulation, and manufacture of products across many different industries. Formula 1 cars, skyscrapers, ships, space exploration vehicles, and many of the objects we see in our daily lives are being conceived and manufactured using our Product Lifecycle Management (PLM) software.

Imagine shaping the experience of a leading physics simulation platform - bringing intuitive, client-side solutions to life across desktop and cloud. As a Java UI Developer, you’ll join our collaborative Java Framework team, contributing to Simcenter STAR-CCM+ by building and evolving the Java-based client infrastructure across API and UI layers, working in close partnership with our Core Framework colleagues.

You care deeply about clean, modular design, long-term maintainability, and user experience, and you’re confident suggesting improvements that elevate both code and collaboration. You’ll contribute thoughtfully to a shared codebase used by a global community of over 300 developers, balancing attention to detail with the confidence to evolve and enhance existing solutions.

If you’re energised by innovation, collaboration, and the opportunity to grow your impact in a supportive, diverse environment, we’d love to hear from you!
