Cryogenics Engineer (f/m/d)

• Cryogenic thermal design & simulation. Build and maintain the thermal-network model of the cold mass: heat-load budgets across the cold and shield stages, multi-layer insulation (MLI) and radiation shielding, conduction through supports and feedthroughs, and AC loss — the heat the cycling magnetic field induces in the superconductor — from the moving magnetocaloric regenerator, and optimization of the hybrid current leads. Your model is the design authority for everything below room temperature.

• Cryostat design & manufacturer interface. Design and specify our bespoke cryostat — vacuum vessel, MLI, thermal shield, cold-mass supports — with a first-of-its-kind twist: a warm bore with a room-temperature regenerator moving through it. You write the specification, run the RFQ, coordinate the cryostat manufacturer through build and first-article acceptance. This is a long-lead item on the program’s critical chain; you drive it.

• Cold head & compressor. Evaluate, select, and qualify cryocoolers and their helium compressors: manufacturer evaluation, test purchases, commissioning, and duration testing.

• Current leads. Design and procure current leads feeding the coils — the classic heat-leak-vs-ohmic-loss optimization, yours to solve.

• Build, integration & validation. Assemble and integrate the cryogenic module: vacuum leak-checking, pump-down iteration, cooldown, steady-state heat-load measurement — and the AC-loss-under-cycling measurement. The data you produce baselines the design of the full-scale machine.

• Research-bench cryo operations. Support our high-field test bench as its cryogenics hand: helium handling, vacuum systems, cryostat operations, and safe cryogenic work practices across the lab.

• Simulation, specification, procurement, build, and the validation measurement are a single scope — you see your own model confirmed (or corrected) by your own data.
• First-of-kind hardware: a warm-bore cryostat with a moving room-temperature regenerator inside exists in no catalogue; you design it with the manufacturer.
• Dry by design: the product is cryogen-free — liquid helium stays in the research lab, so what you build is industrial cooling hardware, not lab apparatus. 

We believe in science; we believe in facts. Climate change is speeding up more than ever and we need to do something about it. We are convinced that we need better technologies to overcome this tremendous challenge – or more precisely: this tremendous threat to humanity. We are on a mission to decarbonize the refrigeration industry and reduce its contribution of 7% to global greenhouse gas emissions.
