Radiation Protection Physicist / Engineer

About the role

The Paul Scherrer Institute (PSI), Switzerland's largest research institute for natural and engineering sciences, is recruiting a Radiation Protection Physicist / Engineer for its Decommissioning Studies Group within the Department of Radiation Safety and Security. This is a fixed-term project position of three years, starting immediately, based in Villigen.

Key responsibilities

• Provide radiation protection expertise and technical guidance for projects, especially developing the TATTOOS radioisotope-production facility as part of the PSI's large-scale IMPACT project.
• Organize, implement and evaluate radiation protection measurement campaigns at PSI, mainly within the IMPACT project, including analysis and interpretation of the data.
• Develop radiation protection concepts and methods for measuring ionizing radiation (e.g. clearance measurements, decommissioning, characterization of radioactive materials) and prepare expert reports, using Monte Carlo simulations where needed.
• Support planning and implementation of decommissioning of former research reactors, including optimizing clearance measurements through automation and software development.
• Prepare license and release applications for the regulatory authorities.
• Write technical reports, quality management documents and scientific publications, and present results at national and international conferences.

Required profile

• PhD in physics or engineering, or master's degree with equivalent research experience.
• Solid expertise in radiation physics, protection and measurement technology.
• Practical experience with measurement campaigns and experiments at particle accelerators and/or radioisotope-production facilities is a plus; experience with nuclear installation decommissioning is an asset.
• Excellent spoken and written English; German is required, or a strong commitment to learning it quickly.

Required skills

• Data analysis, data visualization and programming (e.g. C++, Python).
• Knowledge of Monte Carlo radiation transport codes such as FLUKA, Geant4 or MCNP.

Applications are submitted online by 4 January 2027.
