Quantum Computing Jobs

IonQ · Oxford

Build and operate the software controlling the supporting hardware of trapped-ion quantum computers, from cryogenic compressors to lasers, wavemeters and sensors. You'll own device controllers end to end — API design, implementation, fleet rollout and operational health — working in a Rust codebase with hardware protocols like SCPI, serial, TCP/IP and USB alongside software, systems and quantum science teams.

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.

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.

Rigetti · Berkeley, United States · US$190,000 – US$240,000 pa

Hands-on role owning networking and physical infrastructure across Berkeley labs and a Fremont fabrication facility, including routing, racking, cabling, switches, firewalls and storage, while also supporting AWS cloud environments and infrastructure-as-code. The engineer flexes between data center work and cloud/DevOps tasks such as Terraform, Kubernetes and CI/CD, building new infrastructure as lab and fab space expands.

Infleqtion · Oxford

Lead scientist role focused on quantum radio frequency (QRF) research within a global quantum technology company. Involves driving experimental work on atom-based quantum sensors and platforms, bridging fundamental physics with commercial product development. Based in Kidlington, Oxford, with up to two days remote working per week.

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

Hands-on staff engineering role building and operating the control plane that schedules, calibrates and records work across a fleet of trapped-ion quantum computers. You'll write Rust services handling scheduling, exclusive hardware access, result streaming and data durability, working with runtime, systems and operations teams. Deep diagnosis of live-system failures and setting service boundaries are central.

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

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

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

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.
