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. For the Radiation Transport and Multiphysics Group we are looking for a
Physicist or Nuclear Engineer
Your tasks
You will perform advanced Monte-Carlo particle transport simulations with MCNP 6 and/or MCNPX 2.7.0 needed for the operation of PSls High Intensity Proton Accelerator Facility (HIPA), the spallation neutron sources SINQ and UCN at PSI as well as for current and future development and upgrade projects such as SwissFEL and SLS 2.0. Typical examples of these tasks include optimization of the performance of a target station within given constraints, designing shielding using variance reduction methods, calculation of dose rate maps of extended geometries that have to be composed from technical drawings or similar. Other tasks are requested by the Swiss authorities, e.g. for the disposal of radioactive waste, and reports have to be handed in. For these tasks, in-house developed state-of-the-art systems, programs, tools and patches for MCNP(X) source code already exist that you will tailor for the needs of our applications and migrate to higher versions of MCNP. At internal and international expert meetings you will present your results.
Your profile
You are a nuclear engineer or Nuclear/Particle Physicist, with a PhD, well experienced in advanced radiation transport calculations using MCNP(X) and eligible for the MCNP(X) source code license, and having a good understanding of the nuclear physics behind. You have skills in coding of challenging calculational models with demanding geometries, profound knowledge of variance reduction techniques and programming. Fortran, C on parallel CPU's, Python and Perl are of advantage. Moreover you are able to work self-reliant and time efficient in small expert groups as well as in international and multidisciplinary teams towards solving given tasks. It is expected that you are a well-balanced person, communicative, innovative and open-minded for new ideas. You have a good command in written and spoken English; ideally you are also able to speek and write German.
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on-site infrastructure.
