Quantum Computing Jobs

IonQ · Oxford

Architect, develop and maintain advanced UVM/SystemVerilog verification environments for complex FPGA designs, defining verification plans with constrained-random testing and functional coverage. Build automated regression suites and CI pipelines, and debug issues with RTL designers to support quantum control systems.

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.

Universal Quantum · Haywards Heath

Design, model and test waveforms that transport ions quickly and efficiently on surface ion traps, including inter-module connections via UQConnect. The role also involves contributing to ion trap designs, building accurate physics models and optimisation software, and working with hardware teams to implement transport methods and analyse experimental results against predictions.

Universal Quantum · Haywards Heath

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.

IonQ · Oxford

Owns supplier quality end to end, from auditing and qualifying new suppliers through incoming inspection, first article inspection and source release decisions. Leads the Supplier Corrective Action Request process, chairs the supplier quality position at review boards, and flows UK export-control and Cyber Essentials requirements down to suppliers. Around 25-50% travel for supplier visits and audits.

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

Lead end-to-end delivery of the Systems Software roadmap across five engineering teams (runtime, orchestration, quantum tools, controllers, transport) for concurrent next-generation quantum system programmes. Own planning, dependency management, risk surfacing and status reporting, working with hardware, science and US-based teams to make capacity decisions explicit.

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.

IonQ · Oxford

Lead a team of three electronics engineers within the Systems team, acting as a player-coach with roughly 60% leadership and 40% hands-on design. Own the electronics roadmap for quantum systems, covering schematic capture, PCB layout, mixed-signal and high-speed digital design, and the transition from prototypes to rack-ready production hardware.

IonQ · Oxford

Build and lead a team owning the hardware test estate for quantum-computer control software, from CI systems to new QA and staging rigs. Define test-system architecture, plan builds with Manufacturing, and shape testing strategy across simulation and hardware-in-the-loop. Act as test architect, driving automation and self-service rig usage.

IonQ · Oxford

Keeps a fleet of quantum computers running by root-causing mechanical, vacuum, cryogenic and thermal faults on live systems and prioritising fixes by uptime impact. Designs, prototypes and tests solutions to recurring failures, then writes assembly and upgrade instructions to roll changes into existing fleets, maintaining PLM records and ECRs so fixes carry into future builds.

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

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.

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.

Universal Quantum · Haywards Heath

Designs and architects a custom RF delivery system, including cables and transmission lines, defining specifications and trade-offs for key building blocks. Oversees RF design, simulation, integration, verification and validation testing, and contributes to proof-of-concept work. Works cross-functionally with electronics, ASIC, mechanical, software engineers and physicists, with involvement in project planning and risk management.
