The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of matter and materials, energy and environment and human health. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2100 people.

The Science IT section is responsible for supporting a range of world-class facilities and experiments conducted at PSI. The section currently has expertise and provides support in HPC and cloud computing for data intensive experiments through to experiment domain expertise and low-level algorithm development and deployment on GPU technology. We are also engaged in a number of national and international collaborations with similar institutions across the globe, all with the common goal of maximizing the use of large-scale facilities for science by the provision of cutting edge IT infrastructure and software.

For Development and Consulting we are looking for a
