Post-doc position in theoretical particle physics

Are you excited about the big puzzles in particle physics and interested in carrying out research in theoretical particle physics The theoretical particle physics group at the University of Amsterdam is looking for a postdoctoral researcher interested in the phenomenology of precision experiments in particle physics.

Join Us!

We are seeking a postdoctoral researcher under the supervision of Jordy de Vries who focusses on precision calculation for low energy searches for beyond the Standard Model physics.

This is what you will do

In particular you will investigate the role of radiative corrections in beta-decay processes new methods to better understand neutrinofull and neutrinoless double beta decay and a novel theoretical framework for electric dipole moments. The project is part of an ERC grant and will be team-based and collaboration with other group members is expected. You will have the opportunity to (co-)supervise PhD and/or master students.

What we ask of you

• We are looking for someone with a PhD degree (or close to obtaining one) in theoretical particle physics;
• an interest in precision calculations for precision experiments in particle physics;
• You are a collaborative researcher who is interested in helping the supervision of PhD and Master students;
• You have a professional command of spoken and written English.

It is a preference if you additionally have experience in quantum field theory and (chiral) effective field theory.

This is what we offer you

We offer a temporary employment contract for 38 hours per week for a period of 12 months and the possibility to be extended for another 24 months upon satisfactory performance (36 months in total). The preferred starting date is October 1 2026. The gross monthly salary based on 38 hours per week and dependent on relevant experience ranges between 3546 to 5538 (scale 10). This does not include 8% holiday allowance and 83% year-end allowance. The UFO profile Postdoctoral Researcher level 4 is applicable. A favourable tax agreement the 30% ruling may apply to non-Dutch applicants.

You will work in this team

The Faculty of Science has a student body of around 8000 as well as 1800 members of staff working in education research or support services. Researchers and students at the Faculty of Science are fascinated by every aspect of how the world works be it elementary particles the birth of the universe or the functioning of the brain.

The Institute of Physics (IoP) of the University of Amsterdam is located in the center of the Amsterdam Science Park. The IoP as part of the Faculty of Science is housed in a modern building with excellent labs and technical facilities. Surrounded by several national research institutes and with our partners at the Vrije Universiteit (VU) Amsterdam the institute is part of a strong physics center of international standing.

The faculty members working on theoretical particle physics at the Institute of Physics of the University of Amsterdam are Eric Laenen (Phenomenology of the Standard Model especially Quantum Chromodynamics) Jordy de Vries (Beyond-the-Standard Model effective field theories fundamental symmetries neutrinos) and Wouter Waalewijn (Higgs and jet physics effective field theories factorization and resummation).

The Institute for Theoretical Physics (ITFA) covers many other areas and there is a large research group working on gravitation and astroparticle physics: the GRAPPA institute. Naturally there are strong links with Nikhef which is the national laboratory for particle and astroparticle physics research) and is across the street from the University of Amsterdam. Nikhef has both theory and experimental groups (including ATLAS LHCb ALICE Xenon and NL-eEDM) and there are many opportunities to interact. The research of the Nikhef theory group include higher-order calculations and jet physics in perturbative Quantum Chromodynamics parton distribution functions flavour and neutrino physics effective field theories precision tests of the Standard Model cosmology and gravitational waves.

If you feel the profile fits you and you are interested in the job we look forward to receiving your application via this link. Applications are accepted exclusively through the Nikhef website Post-doc position in theoretical particle physics Jobs accepts applications until and including 3 January 2026. Applications submitted by email or through other portals will NOT be considered.
