Senior AMO Physicist
Join QFX and help build the future of quantum hardware.
Who We Are QFX is a UK-based deep‑technology company focused on the development of advanced quantum hardware components for next-generation computing, communication, sensing, and timing systems.
The Company specialises in precision atomic and photonic technologies, operating at the intersection of fundamental physics and engineering to deliver scalable infrastructure for the quantum technology ecosystem.
The Company is headquartered in Oxfordshire and operates from laboratory and manufacturing facilities at Begbroke Science Park.
Role Overview The Company is seeking to appoint an Atomic, Molecular and Optical (AMO) Physicist to support the continued advancement of its core technology platforms.
This role will contribute directly to the design, development, and validation of precision atomic systems, including atomic beam sources, laser‑based subsystems, and vacuum‑integrated quantum devices.
The successful candidate will work within a multidisciplinary team and play a key role in translating cutting‑edge scientific concepts into robust, scalable, and commercially deployable hardware solutions.
What You’ll Be Doing Duties may adapt in line with business priorities and typically include: · Apply theoretical and experimental AMO physics expertise to advance quantum device development · Develop Python/Julia scripts for analysing raw experimental data and extracting actionable insights · Integrate opto-mechanical systems, electronics, and software into cohesive platforms · Support equipment setup, system demonstrations, and technical troubleshooting · Identify suitable materials and components to meet project specifications · Maintain detailed documentation of project progress and proactively resolve issues
