Quantum Computing Jobs

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

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.

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.

Rigetti · Fremont, United States · US$170,000 – US$200,000 pa

Owns the health and performance of production PVD deposition modules used to fabricate superconducting quantum processors, developing, optimising and qualifying thin-film processes via SPC and data analysis. Works cross-functionally with equipment, facilities, integration and quantum engineering teams, with growing scope to set technical direction and mentor engineers.

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 a service or subsystem of the control plane that schedules and arbitrates access to trapped-ion quantum computers, keeping them calibrated and productive. Involves Rust, async programming, gRPC/REST services, PostgreSQL state machines, concurrency and failure handling, plus moving live systems onto new behaviour. Works closely with runtime, systems and operator teams.

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.

IonQ · Oxford

This role involves leading the validation and characterisation of analogue and mixed-signal ASICs for trapped-ion quantum processors. Responsibilities include developing validation strategies, building reusable hardware and software, and conducting cryogenic measurements to ensure silicon acceptance.

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

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.

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.

Rigetti · US or UK Locations

Deploys and operates Rigetti quantum systems at customer sites, owning technical work from initial bring-up through sustained cloud operation. Specialises in either systems integration (cryogenic hardware, qubit and fridge characterisation) or gate calibration (1Q/2Q gate performance, automated recalibration, production monitoring). Requires up to 25% international travel and close collaboration with internal R&D teams.

Universal Quantum · Haywards Heath

Design, model and test high-fidelity quantum operations, developing control methods and accurate physics models based on real hardware specifications. Work closely with hardware teams to implement new methods on quantum devices, build benchmarking procedures and compare experimental results against theoretical predictions.

Universal Quantum · Haywards Heath

Operate, monitor and maintain ion-trap quantum computing hardware and experimental systems, running calibration, optimisation and characterisation of quantum hardware and control systems. Work closely with physicists and engineering teams to integrate and test new hardware, collecting and analysing experimental data to support performance and troubleshooting.
