Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world‑leading trapped‑ion technology, we’re building the most powerful, accurate and reliable quantum systems to tackle problems that today’s supercomputers cannot solve. Joining Oxford Ionics means becoming part of a global IonQ team that is transforming the future of quantum technology—faster, at scale, and with real‑world impact.

We are looking for a Senior Scientist to join our QPU Testing team. In this role, you will serve as a trusted internal authority on system‑level issues (e.g., optics, vacuum, electronics, and controls) encountered during test plan execution, contributing to the team's mission of improving quantum computer performance through validation of QPU designs and verification of individual QPUs produced by the manufacturing team. You’ll play an important part in shaping the reliable delivery of cutting‑edge QPUs in support of our work in building the world's most advanced quantum systems.

In this position you will work on QPU characterisation using a fleet of ion‑trapping testbeds, supporting the effective delivery of novel quantum processors for pushing the performance boundaries of quantum computers. You’ll have the opportunity to be hands‑on in the build, commissioning, maintenance, and upgrade cycle of on‑site Oxford systems, while assessing the impact of system changes and coordinating integration details with systems engineering, contributing directly to the success of advanced QPU development and manufacture.

  • Drive creation and evolution of validation test plans, procedures, and acceptance criteria, taking into account new testbed features developed by the Systems team.
  • Translate system changes into practical, executable test coverage and readiness standards for QPU testing platforms.
  • Drive structured troubleshooting of cross‑domain system issues encountered during testing and close the loop on corrective actions.
  • Execute and validate testing campaigns, including hands‑on operation and troubleshooting of trapped‑ion systems in Oxford.
  • Support on‑site Oxford system builds, commissioning, maintenance, and upgrades, establishing stable operational baselines by following and contributing to bring‑up procedures.

To be successful in this position, you will need a strong background in building and operating complex atomic systems (UHV, cryogenics, advanced control hardware and software). You must be able to debug technical issues encountered during test plan execution, work cross‑functionally to obtain reliable solutions, and contribute effectively within a fast‑moving, highly technical team. Clear communication skills and the ability to coordinate across time zones and disciplines are essential.

  • Hands‑on experience operating a trapped‑ion experiment.
  • Strong cross‑domain experimental intuition working with elements such as optics, laser, vacuum systems and control electronics, with comfort debugging at the system level.
  • Proven ability to work independently, identifying next steps, and to execute without heavy oversight.
  • Willingness to work hands‑on building and maintaining systems.
  • PhD in experimental physics, or a closely related field, and at least two years of industrial experience.

Additionally, demonstrated ownership of integration across subsystems, including managing change impact and translating engineering changes into reliable operations, would be beneficial. Experience working with Python‑based tooling for experiment control and monitoring is advantageous.

Be part of a team that's shaping the future of quantum. We offer more than just a role; you’ll join a worldclass community of scientists, engineers and innovators working to unlock the full potential of quantum computing. We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more. We're proud to be an equal‑opportunity employer and welcome applicants from all backgrounds.
