Quantum Computing Jobs

• Haywards Heath
• On-site
• Permanent

Provide optical engineering support to a team developing commercial trapped-ion quantum computers. Design, assemble, align and characterise laser and optical subsystems, integrate fibre-optic and opto-mechanical assemblies, and develop test methods to improve alignment stability and throughput. Work alongside electronics, mechanical, physics and quantum engineers.

• Haywards Heath
• On-site
• Mid-level
• Permanent

Hands-on electronics role focused on the hardware system design and realisation of a large-scale control system for quantum computers. Involves analogue and digital circuit design, CAD and test equipment, documentation and verification, plus close collaboration with mechanical engineers, software engineers and physicists on proof-of-concept work.

CAD

• Oxford
• Senior

Keeps a fleet of quantum computers running by root-causing mechanical, vacuum, cryogenic and thermal faults on live systems and prioritising fixes by uptime impact. Designs, prototypes and tests solutions to recurring failures, then writes assembly and upgrade instructions to roll changes into existing fleets, maintaining PLM records and ECRs so fixes carry into future builds.

SolidWorks

• Oxford
• Senior

Owns mechanical design of ion-trap quantum computer hardware, from first requirements through manufacture and integration. Produces CAD assemblies, drawings and BOMs for cryostat, vacuum and cooling systems, routes cabling and optical fibre, and supports lab technicians. Works with scientists and hardware teams on complex multidisciplinary systems.
