Postdoctoral Research Assistant LZ Experiment

Location: Particle Physics, Department of Physics, Denys Wilkinson Building, Keble Road, Oxford, OX1 3RH

Applications are invited for a Postdoctoral Research Assistant on the LZ and XLZD experiments.

A full-time post is available for a fixed-term duration until December 2027, with an opportunity to extend subject to funding.

The LZ experiment is a world leading dark matter search utilizing a liquid xenon time projection chamber to search for particle dark matter. Operating since 2021, we continue data-taking and analysis in search for dark matter and other new physics signals. The XLZD experiment is the next-generation detector, and the Oxford group is working on the fieldcage design.

The successful candidate will analyse data from the LZ experiment and will work on the design of the XLZD fieldcage. They will work with collaborators to design, evaluate the design, and determine cost and schedule of construction of the XLZD fieldcage. On LZ their analysis will enhance the separation of accidentals and low-energy signals, characterise background populations, improve event reconstruction, and understand detector effects.

They will contribute to LZ operations and performance optimisation.

This will involve adapting existing and developing new scientific techniques; contributing ideas for new research projects; collaborating in the preparation of scientific reports and journal articles and occasionally presenting papers and posters; representing the research group at external meetings & seminars, either with other members of the group or alone; managing their own academic research and administrative activities; and carrying out collaborative projects with colleagues in partner institutions, and research groups.

Applicants should hold, or be close to the completion of, a doctorate (DPhil or PhD) in experimental particle physics or related field and ideally have a strong background in analysis and hardware.

Previous experience with dark matter direct detection experiments or other rare event experiments will be an advantage.

Candidates are expected to demonstrate the ability to communicate effectively, plan and execute research activities, and work in a team.

Teaching duties of up to three hours per week during University term time may be required.

Only applications received by midday (UK time) on 14 August 2026 can be considered.
