Core hours 10–4

Job Description

The future is quantum. Oxford Ionics is a high-performance quantum computing company delivering world-leading innovations to create the most powerful, accurate and reliable quantum computers to solve the world's most important problems. Quantum Computing offers a radically new way of building computers that harnesses the power of quantum physics to outperform conventional supercomputers exponentially. Using our unique trapped-ion technology, we are at the forefront of the race to unleash the real potential of quantum computing.

What to expect

The Quantum Infrastructure team is responsible for designing, building, commissioning, and operating the quantum systems that power our ion trap quantum processors. The team's scope encompasses various systems and technologies, such as cryogenics, ultrahigh vacuum, superconducting magnets, and narrow linewidth lasers of across the visible and NIR spectrum. They also have extensive knowledge in the installation of crucial components such as PCBs, optical cavities, AOMs, optical fibres, and modulators that are vital for the operation of our quantum systems.

What you’ll be responsible for

You will be responsible for designing new optical systems such as AOM switchboards, ion imaging systems, and laser stabilisation systems and supporting and training the technician team in assembling, commissioning and maintaining our quantum computers. The role also involves specifying and designing new quantum systems to meet broader science and technical objectives and leading the assembly and commissioning of these systems. You will work across the business to deliver the quantum systems and with technicians to assemble and test and bring new systems online, help trap the first ions in new systems and improve the reliability of existing systems.

The role also involves debugging issues with existing quantum systems and specifying optical systems to meet science requirements. Additionally, you will work collaboratively to implement these designs and support technicians and engineers to carry out routine maintenance of optical systems, as well as ion trap replacement operations. Commissioning new systems such as trap beam alignment, working with electrical engineering on in-situ PCB testing, trapping ions in new systems, configuring and debugging control system problems, gathering specs, and designing new systems to meet science goals are other responsibilities of the role.


You will need a strong background in AMO or trapped Ion physics. You must have experience designing and aligning free space optical systems, along with experience working with lasers. A proven track record in experimental atomic/AMO/ion trapping systems and designing and building atomic physics experiments is essential.

Additionally, experience working with UHV, diode lasers, laser stabilisation, and cryogenics is desired. Proficiency in Zemax for optical design, programming skills in Python and Artiq, and knowledge of mechanical design and CAD are also desirable. Knowledge of electronics is a plus. If you enjoy building and operating systems, want to work towards building the highest-performing quantum computers in the world, and have a passion for solving problems and making things extremely robust, this role is for you.

Excellent communication skills are invaluable, especially when working in a cross-functional team. We are particularly interested in individuals with expertise in communicating technical scientific requirements to diverse departments, backgrounds, and areas of specialisation.


Oxford Ionics is at the cutting edge of quantum innovation. We need people like you with the necessary skills, vision and capability. In return, we'll recognise your engagement and excellence with a range of benefits. You'll find opportunities to further your career with a world-class team, business stock options, unlimited annual leave, flexible working hours with either hybrid or onsite working, private medical insurance for you and your family and much more.

Oxford Ionics is committed to equal opportunity for all.
