Thermal Systems Engineer

As Thermal Modeling & Cryogenic Systems Engineer (Quantum Hardware) , you will play a central role in enabling the next generation of our quantum computers. You will own the thermal architecture and thermal models of complex cryogenic quantum systems that combine a growing number of qubits with increasingly sophisticated cryo-electronics.

Your work will be critical to ensuring system scalability, thermal stability and quantum performance.

You will operate at the intersection of cryogenics, thermal physics, electronics, and quantum hardware whilst working closely with quantum physicists and engineers.

Key responsibilities:

Develop and maintain system-level thermal models of quantum hardware systems, including qubits, wiring, passive components, and cryo-electronics across all cryogenic stages

Work closely with system engineers and physicists to identify thermal constraints and scaling bottlenecks, evaluate architecture options and guide system design decisions.

Own the thermal budget, including trade-off analysis of different technological options (qubit architectures, wiring schemes, cryo-electronics integration levels, materials)

Own the thermal performance of cryogenic quantum hardware platforms by defining and executing validation experiments, correlating predictions with measurements, investigating discrepancies and implementing solutions to inform thermal and system architecture decisions

Design and evaluate thermalization strategies for signals, wiring, and cryo-electronics, including materials and interfaces, to minimize heat loads while preserving signal integrity.

Participate in the integration and operation of cryogenic test platforms, including instrumentation, thermal characterization and investigation of unexpected system behavior

Document thermal assumptions models, and design rules to support product development
