Applications are invited for a Postdoctoral Research Assistant in Particle Physics. The post is available initially for a fixed-term duration of 3 years, with the possibility of extension. The holder of this post will work on the T2K, Hyper Kamiokande (HK) and potentially Super-Kamiokande (SK) experiments which are in Japan. T2K and SK have, and HK will dramatically extend, world-leading sensitivity across a broad range of physics topics from CP-violation in the neutrino sector, baryon number non-conservation and supernova burst neutrino detection for more than a decade to come. The post holder will work with other members of the Oxford group, and other UK and international groups to provide operational support of the DAQ for the recently upgraded ND280 near detectors in Tokai. They will also help with the DAQ for HK, in particular with any necessary adaptations at ND280. They will also take a lead role in development of analysis efforts within the Oxford group for example in neutrino oscillations or supernova burst neutrinos. Applicants should hold, or be close to completion of, a PhD/DPhil in physics or a related field and ideally a strong background in particle physics. Previous experience in the field of neutrino physics and/or data acquisition in high-energy physics experiments will be an advantage. Candidates are expected to demonstrate strong research skills, the ability to work both independently and within a team and to communicate effectively. Willingness to travel to Japan is a must. The post-holder will have the opportunity to teach. Only applications received promptly by 12:00 noon UK time on 15 January 2025 can be considered. Please read the “Person Specification and Job Description” before preparing your application. You will be required to upload a Curriculum Vita, a description of research experience and interests and the names and addresses of three referees as part of your online application. In addition, you should arrange for the three letters of reference to be sent to ppadminphysics.ox.ac.uk by the closing date. Applications are acknowledged but not reference letters.
