Join to apply for the Physicist role at the PSI Laboratory for Energy Systems Analysis (LEA).
The Paul Scherrer Institute (PSI) is the largest research institute for natural and engineering sciences in Switzerland. We conduct cutting‑edge research in future technologies, energy and climate, health innovation, and fundamental science. By pursuing fundamental and applied research, we work on sustainable solutions that address major challenges facing society, science, and the economy. PSI employs 2,300 people, including a fourth of its staff who are post‑docs, post‑graduates or apprentices.
Position Overview
For the section Expertise and Analyses within the Department of Radiation Safety and Security, we are looking for a Physicist. This is a fixed‑term position with a 3‑year employment contract.
Responsibilities
* Concept development, organization, execution, evaluation, and interpretation of radiation protection measurement campaigns at PSI and external facilities, primarily within an international project collaboration.
* Preparation of radiation protection assessments (potentially using simulation tools).
* Development of radiation protection concepts (e.g., for clearance measurements or characterization of radioactive materials) and methods for measuring ionizing radiation according to the needs of the section.
* Preparation of technical reports, quality‑management documents, and scientific publications.
* Presentation of results at specialist meetings and international conferences.
* Performing work in supervised and controlled radiation areas.
Qualifications
* University degree in Physics or Engineering, preferably with a PhD.
* Solid expertise in radiation protection, radiation physics, and radiation detection and measurement. Practical experience with measurement campaigns and experiments at particle‑accelerator facilities is an asset.
* Excellent command of English (spoken and written) and willingness to learn German.
* Strong skills in data analysis, data visualization, and programming (e.g., C, Python).
* Knowledge of one or more major Monte Carlo radiation transport codes (FLUKA, Geant4, MCNP) is an asset.
Benefits
* Interdisciplinary, innovative, and dynamic collaboration.
* Systematic training on the job and personal development opportunities.
* Pronounced vocational training culture.
* Support to optimally combine work and family life or other personal interests through modern employment conditions and on‑site infrastructure.
