Quantum Computing Jobs

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

Lead testing of integrated electronic circuits and subsystems, designing and building analogue and digital electronics using CAD tools and test equipment. Document circuits and verification tests while collaborating with mechanical, software and physics teams to build test systems for quantum computers.

• Haywards Heath
• On-site
• Permanent

Drive HDL system design and realisation for control systems used in quantum computers, documenting circuits and verification tests. Work within a multidisciplinary electronics team alongside mechanical engineers, software engineers and physicists, contributing to proof-of-concept work and project planning. The role sits at the intersection of state-of-the-art electronics and quantum computing hardware.

• 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.

• Haywards Heath
• Hybrid
• Permanent

Designs and models atom-light operations such as sub-Doppler cooling, state preparation, detection and quantum gates, and develops accurate physics models of ion-laser and microwave interactions. Works closely with hardware teams to implement these methods on quantum computing devices and analyses experimental results against model predictions.

• Haywards Heath
• On-site
• Permanent

Designs and architects a custom RF delivery system, including cables and transmission lines, defining specifications and trade-offs for key building blocks. Oversees RF design, simulation, integration, verification and validation testing, and contributes to proof-of-concept work. Works cross-functionally with electronics, ASIC, mechanical, software engineers and physicists, with involvement in project planning and risk management.
