Quantum Computing Jobs

• Oxford
• Hybrid · 3 days in office
• Senior

Integrate all features needed to operate quantum computers into complex multi-layer chips, taking designs from requirements through layout and tape-out. Work closely with scientists and fabrication engineers on ion trapping chips, routing metal tracks and interfacing with photonics and CMOS, while owning project delivery independently.

• Oxford
• Hybrid
• Senior

Owns a group of non-realtime device controllers end to end, from API design and implementation to rollout and operational health, for hardware such as cryogenic compressors, vacuum pumps, lasers and cameras. Controllers are written in Rust on Linux, using gRPC/REST and instrument protocols like SCPI, Modbus, serial and Ethernet, working closely with systems teams and quantum scientists.

• 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.

• 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.

• Bristol
• On-site
• £40,704 – £51,258 pa
• Senior
• Permanent

Develop next-generation entanglement-based quantum networks over fibre infrastructure, designing and demonstrating systems across lab, metropolitan and national testbeds. Research spans entangled-photon sources, single-photon detection, optical switching, wavelength routing, timing and synchronisation, and network control, with Grade J roles adding research leadership and mentoring.

• London

A speculative general-interest application rather than a defined role, inviting candidates with an interest or experience in quantum technologies to submit details for future openings. Work spans quantum hardware and software, including quantum chemistry, AI, machine learning/QML, encryption, QNLP and algorithms, across London, Cambridge and Oxford.

Quantinuum

• London
• Hybrid
• Mid-level

Develops novel quantum algorithms in computational topology and geometry, characterising resource requirements and noise-robustness, then implementing and optimising them on Quantinuum's quantum hardware using error mitigation and error correction. Works across the full quantum computing stack with hardware, QEC and software teams, and with academic and industry partners on quantum topological data analysis use cases.

• Manchester
• £21,805 pa
• Entry level
• Contract

Builds hybrid quantum-dot–rubidium interfaces for frequency conversion and storage of single photons in warm alkali vapour, combining device fabrication, cryogenic QD optics and atomic-vapour experiments. The work spans optical-setup design, III–V semiconductor and atomic physics, quantum optics and numerical modelling of EIT and four-wave mixing, with links to metro-link quantum network trials.
