Rigetti Berkeley, United States US$175,000 – US$200,000 pa
Lead experimental programs to characterize, calibrate and optimize two-qubit gates on tunable-coupler superconducting processors, isolating error sources such as leakage, crosstalk and decoherence. Develop pulse shaping, dynamical decoupling and automated calibration methods that scale across hundreds of qubit pairs, feeding findings back into device design and fabrication.
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.
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.
IonQ Oxford
Hands-on role supporting the optical manufacturing team building and upgrading quantum computer systems. Day to day involves optical, mechanical and electrical assembly, keeping the lab and workshop tidy and safe, and producing and maintaining technical documentation alongside engineers, scientists and senior technicians.
IonQ Oxford
Lead end-to-end delivery of quantum computing systems to customer sites across Europe and Asia, owning deployment and commissioning from early planning and export through installation, commissioning and handover. Coordinate engineering, science, legal, trade compliance, logistics, facilities, security and customer teams, with around 30-40% travel.
Rigetti Berkeley, United States US$190,000 – US$225,000 pa
Lead a cross-functional team building next-generation superconducting quantum hardware, proposing new technical directions and designing experiments to improve performance and scalability. Own delivery of key quantum technologies, using cryogenic systems, RF and time-domain measurement, and Python to close performance gaps.
IonQ Oxford
As a Senior Mechanical Engineer on the Reliability Engineering team, you will focus on maintaining and improving the performance of IonQ's quantum computers. Your responsibilities include diagnosing and resolving mechanical, vacuum, cryogenic, and thermal faults, designing and implementing solutions, and updating product lifecycle management systems.
IonQ Oxford
Owns mechanical design of ion-trap quantum computer hardware, from first requirements through manufacture and integration. Produces CAD assemblies, drawings and BOMs for cryostat, vacuum and cooling systems, routes cabling and optical fibre, and supports lab technicians. Works with scientists and hardware teams on complex multidisciplinary systems.
IonQ Oxford
This role involves working closely with software engineers, systems teams, and quantum scientists to build and operate the software that controls the hardware surrounding quantum computers. Responsibilities include designing and implementing device controllers, ensuring robustness and observability, and integrating with the wider software architecture.
IonQ Oxford
Join the Runtime Software team to build the real-time control system that turns quantum hardware into a working computer. You'll develop Rust libraries and abstractions over real-time control devices, driving ions with nanosecond precision, and work closely with experimental scientists and compiler teams.
IonQ Oxford
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.
IonQ Oxford
Builds and runs the Kubernetes-based platform behind IonQ's quantum systems, spanning on-site clusters and cloud infrastructure. The role covers CI/CD pipelines, observability for lasers, cryogenics and vacuum hardware, remote development environments, and infrastructure as code with OpenTofu. It involves leading strategic platform projects and working closely with physicists, lab technicians and SRE colleagues.
IonQ Oxford
Join the Runtime Software team to build the real-time control system that turns a collection of hardware into a quantum computer. You'll develop Rust libraries and execution environments, write drivers for real-time devices, and work closely with experimental scientists, FPGA and compiler teams to drive ions with nanosecond precision.
IonQ Oxford
Owns full-chip mixed-signal modelling and verification for cryo-CMOS ASICs used in trapped-ion quantum processors, building Verilog-A/AMS and real-number SystemVerilog models correlated against schematic and measured silicon. Leads AMS methodology, sign-off criteria and reviews, runs Cadence AMS/Xcelium-Spectre co-simulation and regressions, and mentors engineers through tape-out and silicon bring-up.
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.
