Quantum is now, and it's built here.

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.

What to expect:

As a Quantum Scientist, you will be at the forefront of our research efforts, working hands-on with our current hardware while helping to shape future generations of quantum processors. Your work will span designing, debugging, and executing experiments, developing novel control schemes, and pushing the boundaries of system performance.

What you’ll be responsible for: 

• Prototype and characterise coherent control and cooling schemes for trapped-ion qubits using laser and microwave fields.

• Calibrate and benchmark quantum systems, focusing on achieving ultra-low gate errors and optimising performance across device modules.
• Validate emerging trap technologies, including integrated electronics and photonics for large-scale architectures.
• Analyse experimental data, debug complex hardware/software interactions, and ensure reliability of qubit operations.
• Present results internally and externally, representing Oxford Ionics at conferences and in collaborations.

You will need a PhD in physics or a related discipline, with a strong foundation in atomic or qubit-related physics. While prior postdoctoral or industry experience is valuable, this role is also open to candidates moving directly from a PhD. A solid background in quantum control, with hands-on experience in calibration, benchmarking, or coherent control of qubits, will be key to success. Practical skills in control software, hardware integration, or experimental data analysis are also important.

You will need:

• Proven expertise in experimental AMO physics or quantum computing.  Experience with trapped ions is preferred.
• Strong collaborative skills, with the ability to work independently and as part of a fast-moving team.
• Prior experience in one or more of the following: spectroscopy or simulation of multi-level systems, characterisation of control hardware, gate fidelity benchmarking or running algorithms on hardware.
• Strong proficiency in programming and data analysis.
• A track record of scientific communication through publications, talks and conferences.

Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class 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.

Join us and be part of the future of quantum computing.
