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.

At PSI the world’s most intensive sources of low-energy muons, pions and ultracold neutrons are used to carry out experiments at the forefront of low-energy high-precision particle physics. This includes for example MEG II, Mu3e, n2EDM, CREMA, muX, and MUSE.

The activities of the theory group of the Laboratory for Particle Physics (LTP) at PSI are closely aligned with the experimental groups. Apart from research at the high-energy frontier to support the CMS group of LTP, emphasis is put on research of muon and neutron particle physics.

For the Theory Group in the Laboratory for Particle Physics we are looking for a
