IonQ Oxford
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.
IonQ Oxford
Owns the full lifecycle of electrical reliability fixes on operational trapped-ion quantum computers, from triaging and root-causing control and drive-electronics faults to designing, prototyping and retrofitting permanent solutions. Works across Operations, Science and Manufacturing on fleet-wide upgrades, standardising hardware and building telemetry to cut downtime.
Rigetti Berkeley, United States US$220,000 – US$250,000 pa
Lead a cross-functional software engineering team building platforms for quantum device design, chip fabrication workflows, physics-informed data analysis, and QPU characterization. The role is hands-on, spanning team management, architecture, and data pipeline work with Python, AWS, and streaming tools, while partnering closely with quantum hardware, fabrication, and research teams.
Universal Quantum Haywards Heath
Lead multidisciplinary systems engineering across electronic, mechanical, cryogenic, vacuum, optical, software and control domains, owning system-level rigour from concept to customer deployment. Define the systems engineering strategy, lifecycle, standards and toolset including requirements management, MBSE, modelling and configuration control, while chairing design, readiness, test and acceptance reviews. Build and mentor engineering teams across UK and international locations, maintaining system-level plans, dependencies and technical risks to meet programme objectives.
Rigetti Berkeley, United States US$165,000 – US$190,000 pa
Owns the mechanical architecture of quantum hardware systems, from room-temperature infrastructure down to the millikelvin core of dilution refrigerators. Leads the cryogenic signal chain design, thermal interface definition, simulation in COMSOL or ANSYS, prototype builds and qualification, working alongside quantum physicists and RF engineers.
PsiQuantum Warrington £64,000 – £76,500 pa
Develops ultra-low-loss optical interfaces between dissimilar waveguiding platforms, combining device concept design, optical simulation with BeamPROP or FDTD, and hands-on experimental validation of coupling and mode conversion. Works with internal photonics, systems and experimental teams plus external partners to mature practical, manufacturable interface solutions.
Infleqtion Kidlington
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.
Infleqtion Kidlington
Designs, implements and optimises quantum algorithms for simulation, optimisation and hybrid quantum-classical workloads, working with hardware, control and research teams to turn theory into executable applications. Deploys software optimisations to the Superstaq cloud platform using industry-grade engineering practices, supports customers, and contributes to research publications and commercial proposals.
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.
Universal Quantum Haywards Heath
Develop, integrate and test software that operates quantum computing hardware, including benchmarking, profiling and optimising quantum processes and algorithms. Work within a multidisciplinary team of electronic engineers, physicists and hardware designers, taking ownership of major features in the quantum computing software stack.
