Quantum Computing Jobs

PsiQuantum · Warrington · £31,200 – £56,160 pa

Interns in the optical architecture group work at the interface of hardware, manufacturing and quantum architecture, prototyping software to control and simulate optical networks inside photonic quantum computers. They apply quantum information theory, network design and optimisation to improve designs, simulate and benchmark protocols, and document results. Placements run 3-6 months on a rolling basis, with a mix of analytical and programming work.

PsiQuantum · Warrington · £50,000 – £57,000 pa

Designs RF and high-speed electronics for controlling and reading out quantum photonic hardware, including electro-optic modulator drivers, SNSPD readout and low-latency control systems. Works alongside photonics and quantum teams, with FPGA-based design, debugging and lab measurement of complex cryogenic hardware.

Universal Quantum · Haywards Heath

An open application route for quantum physics specialists rather than a defined role, inviting candidates to introduce themselves when no specific vacancy fits. The work centres on engineering quantum computing hardware within a team building large-scale quantum computers. It suits people who want to be considered across multiple potential positions.

Universal Quantum · Haywards Heath

Design, model and test high-fidelity quantum operations, developing control methods and accurate physics models based on real hardware specifications. Work closely with hardware teams to implement new methods on quantum devices, build benchmarking procedures and compare experimental results against theoretical predictions.

Rigetti · US or UK Locations

Deploys and operates Rigetti quantum systems at customer sites, owning technical work from initial bring-up through sustained cloud operation. Specialises in either systems integration (cryogenic hardware, qubit and fridge characterisation) or gate calibration (1Q/2Q gate performance, automated recalibration, production monitoring). Requires up to 25% international travel and close collaboration with internal R&D teams.

Quantinuum · Cambridge

Leads engineering teams building core quantum languages, compilers and toolkits such as Selene, TKET, HUGR and Guppy, balancing people management with technical roadmap execution. Stays hands-on through design discussions, architectural reviews and code problem-solving, and guides tooling from research prototypes to production-grade software. Collaborates with hardware, theory and product teams across global sites, with occasional international travel.

The University of Manchester · Manchester · £21,805 pa

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.

University of Nottingham · Nottingham · £35,608 – £38,784 pa

Conducts original research in quantum information and entanglement theory on an EPSRC/NSF-funded project studying entanglement in heterogeneous chemical reactions, combining quantum information theory, nanoscale sensing and open quantum systems modelling. Involves developing methods to quantify entanglement from experimental measurements, publishing in leading journals, contributing to grant bids, and coordinating meetings across UK and US teams.

University of Bristol · Bristol · £40,704 – £51,258 pa

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.

University of Oxford · Oxford · £39,424 – £47,779 pa

Builds machine learning models and digital twins of quantum devices to study how scaling affects the control and stability of quantum operations. Models the physical and control architecture to identify design bottlenecks and optimisation strategies, using simulators as a testbed for engineering trade-offs. Works with academic teams, industrial partners and national labs within the QCI3 initiative.

Rigetti · Berkeley, United States · US$240,000 – US$275,000 pa

Lead the global deployment, integration and commissioning of on-premise quantum computing systems, building and scaling a Field Engineering organisation. Own site readiness, installation, acceptance and lifecycle support for superconducting processors, dilution refrigerators and RF/microwave hardware, acting as senior technical escalation point and travelling globally around 30-40%.

Quantum Dice · Oxford

Customer-facing technical role translating defence and national security challenges into mathematical models, building prototypes on quantum-enabled simulators and probabilistic hardware, and benchmarking against classical solvers. Spans Solutions, Applied Research, Engineering and Commercial teams, leading projects from requirements capture to pilot under security classification and export control constraints.

Infleqtion · Kidlington

Experimental AMO physicist role focused on inertial sensing applications, translating product requirements into atomic system designs and running modelling, simulation and analytical calculations. You will integrate opto-mechanical systems, electronics and software into quantum devices, execute testing and verification plans, and collaborate with physicists, engineers and technicians in a multidisciplinary team.

Infleqtion · Kidlington

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.

Quera Computing · Didcot

Build and operate a next-generation neutral-atom quantum computer at the Harwell Science and Innovation campus, verifying and validating modules and subsystems with engineering teams. Run, calibrate and improve the QPU, investigate noise and decoherence, and analyse experimental data to guide system improvements alongside physicists, engineers and computer scientists.
