Alpha Cryogenics Engineer

Develop the cryogenic plant and cooling systems for Proxima’s scientific breakeven stellarator, Alpha. This role demands systems thinking, simulation and modelling skills, technical judgement, and the ability to make impactful design decisions. Your deep expertise in thermal analysis and cryogenic plant design will be critical to integrate the advanced cooling systems required to realize Alpha within the ambitious Proxima timelines. Design and analyze integrated cooling systems for the Alpha stellarator and wider cryogenic plant, conducting trade studies between components. Use first principles reasoning and simulation to detail and validate the design of Alpha cryogenic systems. Collaborate closely with electromagnetic, mechanical and electrical engineers, magnet experts, and physicists. Conduct performance analysis and troubleshooting of cryogenic systems. Identify and act as an expert customer for projects with external suppliers and partners to specify and co-design cryogenic systems with the highest quality and speed.
