We are seeking outstanding applicants for several positions of the rank of  associate professor or assistant professor positions in experimental physics at QUP. We are interested in outstanding scientists with excellent track records and international recognition.

International Center for Quantum-field Measurement Systems for Studies of the Universe and Particles (QUP) is a World Premier international research Center Initiative (WPI) promoted by the Japanese government and hosted by High Energy Accelerator Research Organization (KEK), the leading national high energy physics laboratory in Japan. 

QUP aims to explore new quantum fields and forces and probe physical phenomena with extremely weak couplings; such as light dark matter, axions, and gravitational waves, by pioneering the weak coupling frontier through the use of cutting-edge quantum sensors and devices. QUP operates under a distinctive organizational model in which researchers from a broad range of institutions, including KEK, converge at QUP to pursue common scientific objectives. QUP's principal research activities are conducted at its central facility, with additional support provided by satellite laboratories at the University of California at Berkeley (USA), Toyota Central R&D Lab. and ISAS at Japanese space agency JAXA. These programs are designed to bridge quantum technologies with particle and fundamental physics, materials science, and biomedical applications through deeply coordinated, intra-institutional collaboration.

The appointee will primarily engage in one of the following QUP experimental projects shown at https://www2.kek.jp/qup/en/research/, in collaboration with the QUP Principal Investigators (PIs). However, the possibility of proposing new projects in accordance with QUP's research plan remains open.

The contract for this position will be on an annual basis. The renewal of the contract depends on the continuing availability of funds and the fellow's satisfactory job performance. The maximum term of the position is five years, with the possibility of renewal or promotion to a tenured position based on satisfactory job performance, continuing availability of funds, and ongoing operational needs. Salaries are comparable to those at other prestigious institutions. Financial support for starting-up research will also be provided.

As a WPI research center, QUP is designed to establish an international environment where more than 30% of researchers are non-Japanese. English is the official language of QUP. QUP is an equal opportunity employer that will build a diverse community of scientists. We welcome qualified applicants worldwide, including women, persons with disabilities, and underrepresented minorities, regardless of race, color, religion, gender identity, etc.

Applicants should have a Ph.D. in Physics or a related field and more than three years of working experience after receiving a Ph.D. with an outstanding record in experimental cosmology, particle physics, or related fields. The posting shall remain open until the positions are filled. However, for full consideration, we encourage all candidates to apply by August 31, 2025. Applications will only be accepted via AcademicJobsOnline.org. Applicants should submit a curriculum vitae (with an email address and citizenship), a statement of research interests, and a list of publications.
