Quantum Computing Jobs

• Kidlington
• Hybrid
• Mid-level
• Permanent

Builds and maintains CI/CD pipelines, container orchestration and infrastructure-as-code for integrated software, firmware and gateware, including hardware-in-the-loop testing rigs. Also owns lab system management, network and server administration, backup and recovery planning, and software security procedures for production systems. Split between Kidlington and the National Quantum Computing Centre at Harwell, with up to two days remote.

• Kidlington
• Hybrid
• Mid-level
• Permanent

Designs, analyses and implements fault-tolerant architectures for scalable quantum computation, developing error-correcting codes, decoders and fault-tolerant gate constructions tailored to neutral atom hardware. Works with hardware, control and compiler teams to model noise, optimise syndrome extraction and define logical performance metrics, bridging QEC theory and experimental implementation.

• Oxford
• Hybrid
• Senior

Lead validation and characterisation of analogue and mixed-signal ASICs for trapped-ion quantum processors, from test planning and platform development through first-silicon bring-up, debug and system integration. The role spans room-temperature and cryogenic (around 4 K) measurements on packaged parts, chip-on-board assemblies and bare die, with heavy Python automation and test PCB work.

• 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.
