Owns end-to-end delivery of complex quantum systems programs, building roadmaps, milestones and integration schedules across device fabrication, cryogenics, control hardware and software teams. Tracks readiness across hardware, firmware and software layers, manages cross-team dependencies and risks, and establishes scalable program management practices for research-driven deep-tech R&D.

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.

PQShield · Remote); within Belgium, France, Netherlands, UK, Germany. Some travel to our offices will be required from time-to-time

Speculative application for a deep-tech startup building a RISC-V MCU-based subsystem with post-quantum cryptography algorithms and security features. Successful candidates collaborate directly with founders and inventors, working across data science, optimisation and AI in the semiconductor space, with occasional travel to offices.

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 · £64,000 – £76,500 pa

Develops and evaluates advanced optical fibre for high-performance optical systems, combining simulation of modal properties, loss, dispersion and coupling with hands-on experimental measurement and verification. Works with internal photonics, systems and experimental teams plus external development partners to translate system requirements into fibre performance targets and steer design tradeoffs.

Quantinuum · 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.

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.

IonQ · Oxford

Inspects incoming, in-process and finished components against mechanical, electrical and PCBA specifications, interpreting GD&T drawings and programming CMM, OMM or vision systems. Owns the inspection side of the Material Review Board, controlling nonconforming material and closing NCRs, while allocating daily work and guiding less experienced inspectors.
