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.

Driven by a deep understanding of what is required to deliver successful products such as Simcenter STAR-CCM+, a multi-physics computational fluid dynamics (CFD) software for the simulation of products operating under real-world conditions, we enable our customers to design better products faster. Simcenter STAR-CCM+ uniquely brings automated design exploration and optimization to the CFD simulation toolkit of every engineer.

Help our customers transform their business with our world-leading technology!

As a Working Student Performance Testing for Simcenter STAR-CCM+ (f/m/d) in Erlangen, you will execute and analyze performance tests on different HPC systems to ensure our software runs efficiently and reliably on current and upcoming hardware platforms.
