Careers

As one of Europe's leading facilities for high-performance computing, HLRS is a diverse community of scientists, engineers, and other professionals focused on discovering and developing new applications of powerful digital technologies and computer science methods.

The High Performance Computing Center Stuttgart (HLRS) is Germany's first national supercomputing centre. It operates one of the fastest supercomputers in the world and offers access to supercomputers for universities and research institutions as well as industrial partners. HLRS also holds a leading position worldwide in the research areas of parallel computing, cloud computing and high-performance data analysis and is significantly involved in international and national research projects.

For the development of new solutions and support services on the interface between leading edge scientific applications (primarily from the CFD and global system science fields) and high performance computing systems (especially for the flagship HPC system Hawk) we offer two positions in a national project called SiVeGCS as 

Performance Engineer (f/m/d)
