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 future technologies, energy and climate, health innovation and fundamentals of nature. 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 2200 people.

For the Laboratory for Neutron Scattering and Imaging we are looking for a
Postdoctoral Fellow
Scientific programming
Your tasks
The task of your position is two-fold. On one side, we like to use machine-learning concepts to support the users of our instrumentation suite to optimize their measurements strategies. This optimization also include establishing statistical or information theoretical concept to optimize the data acquisition time without compromising on the information contents of the data. This task might also involves interfacing with the software engineers responsible for the data acquisition systems used for the instrumentation at SINQ. The data acquisition software at SINQ is developed collaboratively together with internal and external partners. Occasionally the task requires working in controlled areas (SINQ). Secondly, we like to support the users in the analysis of their data. We like to study algorithms automatically comparing existing and already implemented models for describing scattering patterns with experimental data to help the scientists to select possible models.
Your profile
  • PhD degree in natural science, statistics or informatics
  • Sound knowledge in C/C++ and python
  • Fluent in English
  • Strong background in math and Bayesian methods as well as machine learning and knowledge in scattering theory would be an advantage
  • Ability to independently solve problems and collaborate with internal and international partners
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.
Your employment contract is limited to 3 years.
