Job summary We are recruiting a Cryogenics and Vacuum Engineer who, as a Mechanical Engineer, has an excellent understanding of how to design vacuum/cryogenic equipment to specification. You will work closely with a CAD team to execute iterative workflows. Your role will be responsible for the design, maintenance, and optimisation of vacuum systems and cryogenic equipment used in fusion applications. In this context, you ensure system integrity, thermal performance, safety compliance, and reliable operation of vacuum instrumentation operating in a wide range of rarefaction. Job description You will design and develop high vacuum and ultra-high vacuum systems, evaluate system performance and implement improvements. In addition, you will design cryogenic systems under liquid helium as well as liquid hydrogen temperatures and develop cryogenic piping, insulation, and thermal management solutions to maintain target temperatures. Furthermore, your responsibilities include the integration of cryogenic systems with vacuum environments for cold traps and cryopumping. Essential requirements Master’s degree in mechanical engineering or PhD in a related science/engineering discipline More than 5 years’ experience with engineering and design of vacuum systems (flanges, gaskets, material selection) More than 5 years’ experience with engineering and design of cryogenic systems ( Knowledge of cryogenic engineering principles, thermodynamics, and heat‑transfer modelling Familiarity with vacuum standards and cryogenic safety best practices Curiosity about new technologies and diverse industry knowledge with a proactive approach to learning Advanced proficiency in Microsoft products (Excel, Word etc.) Desirable requirements Experience with nuclear fusion and tritium-compatible design of components Experience with hydrogen safety regulation and design implications Experience working in cross-departmental and cross-cultural teams Experience with helium recovery systems or low‑temperature refrigeration cycles Certification or training in cryogenic safety and pressure systems Working environment We offer a dynamic and inclusive working environment that fosters creativity and innovation. We are committed to work-life balance and offer flexible working hours to support our employees' well-being.
