Quantum Computing Jobs

Universal Quantum · Haywards Heath

Designs RF PCBs and architecture for a custom RF delivery system, including cables and transmission lines, and defines specifications for key building blocks. Oversees RF verification and validation testing and documentation, working closely with electronics, ASIC, mechanical, software engineers and physicists on rapid proof-of-concept work.

Universal Quantum · Haywards Heath

Provide optical engineering support to a team developing commercial trapped-ion quantum computers. Design, assemble, align and characterise laser and optical subsystems, integrate fibre-optic and opto-mechanical assemblies, and develop test methods to improve alignment stability and throughput. Work alongside electronics, mechanical, physics and quantum engineers.

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.

Rigetti · Berkeley, United States · US$180,000 – US$250,000 pa

Builds and maintains data-intensive Python backend services for Rigetti's internal software team, supporting quantum engineers and fab engineers with measurement, characterization and fabrication tooling. Work spans schema migrations, testing, CI, performance and observability, plus frameworks that let scientists use AI coding agents safely. Small senior team, no quantum background required.

Rigetti · Berkeley, United States · US$180,000 – US$230,000 pa

Owns end-to-end deployment of quantum computing systems both on-premises at customer and partner sites and on the cloud platform, acting as the technical point of contact from site requirements through installation, validation and handoff. Combines DevOps work — Kubernetes, AWS, Terraform, CI/CD, observability — with on-site commissioning, SRE support and root-cause analysis, with international travel and on-call during installations.

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

Builds and commissions precision optical and laser assemblies for quantum computing hardware, covering free-space alignment, fibre coupling and testing delicate components under microscopes. Works alongside technicians, engineers and scientists on system builds, maintenance and upgrades, documenting work and maintaining a safe laser laboratory.

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

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

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.

IonQ · Oxford

Integrate all features needed to operate quantum computers into complex multi-layer ion-trapping chips, taking designs from requirements through layout and tape-out. Work closely with scientists and fabrication engineers, handling metal-track routing and interfaces with photonics and CMOS, and independently owning project delivery.

IonQ · Oxford

Hands-on staff engineering role owning the non-realtime control software for quantum computers, integrating supporting hardware such as cryogenic compressors, vacuum pumps, lasers and cameras on general-purpose Linux. You will write Rust controllers and shared frameworks, build simulators and test infrastructure, and diagnose failures that only appear against real hardware in a live lab.
