Quantum Computing Jobs

IonQ · Oxford

Builds the control plane that schedules quantum programs, calibration routines and customer workloads onto trapped-ion hardware, arbitrating exclusive access and streaming results. Owns persistence, data models and migrations, plus tests and harnesses run against real machines and simulators. Works in Rust, PostgreSQL and gRPC alongside runtime, systems and operator teams.

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.

Universal Quantum · Haywards Heath

Design and develop next-generation microfabricated Paul traps for scalable quantum computers, working with users to determine suitable layouts and acting as technical liaison with ion trap manufacturers. Perform electromagnetic and thermo-mechanical analysis and simulation, and collaborate with package designers on assembly procedures. The role also involves documenting designs and simulations.

Universal Quantum · Haywards Heath

An open application route for quantum physics specialists rather than a defined role, inviting candidates to introduce themselves when no specific vacancy fits. The work centres on engineering quantum computing hardware within a team building large-scale quantum computers. It suits people who want to be considered across multiple potential positions.

Rigetti · Berkeley, United States · US$115,000 – US$140,000 pa

Hands-on field role operating, maintaining and debugging RF and cryogenic systems for quantum processors deployed at customer sites worldwide. Owns dilution refrigerator cooldowns, vacuum and helium leak detection, RF hardware validation, and on-call support, with 35%+ international travel.

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

Lead the operation, calibration and characterisation of ion-trap quantum computing hardware, owning experimental performance. Develop methods for quantum measurement and control, applying AMO physics to laser cooling, trapping and detection, and build models to guide optimisation. Mentors junior scientists within a multidisciplinary team.

Universal Quantum · Haywards Heath

Design, build and test thermal control systems and electronic enclosure assemblies for ion-trap quantum devices, integrating mechanical designs with laser and electronic systems. Work within a multidisciplinary team of electrical engineers, physicists and quantum engineers, contributing to project planning, risk management and scheduling.

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.

Universal Quantum · Haywards Heath

Lead the design and operation of a global supply chain for complex quantum computing hardware, managing end-to-end procurement, supplier relationships, and logistics. Work closely with engineering and cross-functional teams to mitigate supply risks and ensure timely delivery of critical components. Implement practical tools and processes to support scaling while ensuring compliance with international regulations.

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.

Universal Quantum · Haywards Heath

Produce high-quality, full-custom, mixed-signal integrated circuit layouts, working across all levels from base cells to chip top-level. Collaborate closely with designers to meet circuit requirements and deliver DRC/LVS-clean layouts on schedule, implementing designs across a variety of fabrication processes.

Universal Quantum · Haywards Heath

A speculative application opening for a quantum computing company, inviting candidates to submit their details for roles that are often not publicly advertised. The team reviews submissions and reaches out to arrange a conversation when there appears to be a potential fit, with new roles being created regularly.

IonQ · Oxford
