Quantum Computing Jobs

• 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.

SolidWorks

• Oxford
• Hybrid
• Mid-level

Build and operate the software controlling the supporting hardware of trapped-ion quantum computers, from cryogenic compressors to lasers, wavemeters and sensors. You'll own device controllers end to end — API design, implementation, fleet rollout and operational health — working in a Rust codebase with hardware protocols like SCPI, serial, TCP/IP and USB alongside software, systems and quantum science teams.

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
• Permanent

Operate ion-trap quantum computing hardware, developing quantum control protocols for ion shuttling and quantum gates. Run calibration, optimisation and characterisation procedures, and build theoretical models and simulations to compare measurements with predicted quantum dynamics. Works within a multidisciplinary team of software, electrical, physics and quantum engineers.

• Warrington
• On-site
• Senior

Develops scalable fibre-to-chip alignment schemes and opto-electronic packaging workflows for chip-based photonic integrated circuits at the UK R&D facility in Daresbury. Involves prototyping packaging flows, reviewing BOMs, sourcing materials with supply chain and external vendors, and transferring designs to manufacturing partners.
