Junior AMO Physicist

About Us

Infleqtion is a global quantum technology company solving the world's most challenging problems. The company harnesses quantum mechanics to build and integrate quantum computers, sensors, and networks. From fundamental physics to leading edge commercial products, Infleqtion enables "quantum everywhere" through our ecosystem of devices and platforms. Our mission is to commercialise atom-based quantum products that provide orders of magnitude improvements in performance and computing applications.

Infleqtion has offices in the USA, United Kingdom, and Australia. This is a full-time position split between our Kidlington, Oxford office and the National Quantum Computing Centre, Harwell. Work from home permitted up to 2 days per week based on business needs and manager approval.

This is an exciting opportunity for an outstanding recent MSc (or equivalent experience) in Physics, AMO Physics, Quantum Physics or a closely related discipline, to contribute to the development of next-generation neutral atom quantum computers. You will work at the forefront of quantum technology, helping to build experimental systems that push the limits of precision measurement, laser control and quantum engineering.

Working alongside world-class physicists and engineers, you will gain hands-on experience with state-of-the-art quantum hardware, including laser-cooled atoms, ultra-high vacuum systems, precision optics and quantum control. From day one, you'll contribute to real quantum computing systems while receiving mentoring and increasing technical ownership as your experience grows.

Whether you aspire to become a leading experimental physicist, develop breakthrough quantum technologies or help build commercially useful quantum computers, this role offers the opportunity to make a meaningful impact early in your career.

• Work on one of the world's most advanced neutral atom quantum computing platforms.
• Gain hands-on experience with cutting-edge experimental quantum hardware from your first day.
• Learn from experienced scientists and engineers who are shaping the future of quantum technologies.
• See your work rapidly transition from laboratory experiments into commercial quantum computing systems.
• Develop expertise across AMO physics, lasers, optics, control systems and quantum engineering in a collaborative environment.

• Build, operate and improve cutting-edge experimental quantum systems alongside experienced physicists.
• Assist with the integration of optical, mechanical, electronic and software components into working quantum devices.
• Perform precision experiments on laser-cooled atomic systems, analyse results and contribute to the development of next-generation quantum computing hardware.
• Help characterise and optimise system performance through testing and troubleshooting.
• Contribute to the maintenance, alignment and optimisation of laser systems and optical setups.
• Assist with equipment installation, commissioning and laboratory organisation.
• Document experimental procedures, results and technical findings.

• Work collaboratively with physicists, engineers and software developers to develop commercial and research quantum technologies.
• Continuously develop new experimental skills while contributing ideas to improve the performance and capability of our quantum systems.
• Participate in technical discussions, design reviews and problem-solving sessions.
• Manage priorities effectively while working in a fast-paced research and development environment.
• Contribute positively to an open, collaborative and supportive team culture.

• Present experimental findings and progress during internal meetings.
• Contribute to technical reports, documentation and, where appropriate, scientific publications.
• Attend project meetings, workshops and conferences as opportunities arise.

• MSc in Experimental Atomic, Molecular and Optical (AMO) Physics or a closely related discipline, or equivalent experience.
• Passion for quantum technologies and a desire to help build the next generation of quantum computers.
• Strong experimental laboratory skills.
