Cryogenics Engineer

Your work will be critical to the success of Alpha, Proxima’s scientific breakeven stellarator. Alpha relies on superconducting magnet systems that must operate at cryogenic temperatures to generate the magnetic fields required to confine plasma. As a Cryogenic Engineer, you will design, analyse and validate the cryogenic systems that enable these magnets to perform reliably. Applying expertise in thermal engineering, fluid dynamics, and cryogenic system design, you will develop advanced cooling solutions for a first of a kind fusion machine. This role requires a unique combination of advanced systems thinking, simulation and modelling skills, and hands-on technical judgement. You will move between analysis and implementation, turning complex designs into reliable cryogenic systems through testing, troubleshooting, and validation.

Responsibilities

Specify, design, and analyze specific cooling system to meet cryogenic performance requirements, ensuring model accuracy is verified by testing protocols; Provide hands-on technical leadership during the construction, commissioning, and long-term operation of the cryogenic plant and its subsystems; Conduct performance analysis, testing, and troubleshooting of cryogenic systems; Collaborate closely with electromagnetic, mechanical and electrical engineers, magnet experts, and physicists; 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

Requirements

A team player who enjoys tackling difficult challenges, exploring new approaches, and continuously improving through iteration; An engineer who combines strong modelling skills with hands-on experience building and operating cryogenic systems; Experience in cryogenic hardware design, commissioning, and operation; Proven track record in specifying and designing cryogenic cooling systems using both multi-physics tools (ie Simcenter Amesim, Comsol) and reduced-order modelling approaches; Experience validating cryogenic systems through a combination of simulations, testing, and prototyping; Demonstrated ability to lead external work packages and manage procurement projects
