Job Description
Your responsibilities
Are you passionate about measuring thermal properties in extreme environments? Do you have hands-on experience with cryogenic technologies and advanced measurement techniques?
This could be your next opportunity. Join CERN and become part of a multidisciplinary team dedicated to testing and qualifying a wide range of materials and components used in cutting-edge scientific research.
As a Cryogenic Engineer in the Engineering Department (EN) — which drives technological innovation to enable ground breaking physics experiments — you will join the Mechanical & Materials Engineering Group (MME) and work within the Mechanical Measurement Laboratory. This lab carries out precise physical and mechanical measurements on components and systems developed for current and future high-energy physics projects.
In this role, you will:
- Develop and operate advanced thermal property measurement systems, including setups for measuring thermal conductivity and specific heat at cryogenic temperatures, down to 2 K.
- Contribute to the validation and optimisation of cryogenic instrumentation and experimental techniques used across CERN and in collaboration with international partners.
- Collaborate closely with multidisciplinary teams, including engineers, material scientists, and external research institutions, in the framework of R&D initiatives and global projects such as VAMAS.
- Support the design, commissioning, and continual improvement of cryogenic test benches.
We are looking for a motivated engineer or scientist who thrives in a hands-on laboratory environment and is eager to push the limits of material testing under extreme conditions.
CERN — take part and help shape the future of science.
Your profile
Skills:
- Knowledge of cryogenic systems;
- Hands-on laboratory experience;

About us
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
Diversity has been an integral part of CERN's mission since its foundation and is an established value of the Organization. Employing a diverse workforce is central to our success.
