Research Assistant - Data Analysis on the Hyper-Kamiokande Detectors (Open)

The Hyper-Kamiokande (Hyper-K) experiment represents the next generation of large-scale water-Cherenkov detectors, designed to significantly advance our understanding of fundamental physics. Building on the legacy of Super-Kamiokande, Hyper-K will feature a massive fiducial volume and enhanced photon detection capabilities, enabling unprecedented sensitivity to rare and elusive processes. The primary scientific goals of Hyper-K include precision studies of neutrino oscillations, the search for proton decay (a key prediction of Grand Unified Theories) and the observation of astrophysical neutrinos from sources such as supernovae.
Hyper-K is expected to begin data-taking by the end of 2027, ushering in a new era of precision neutrino physics. Supporting this flagship detector is a suite of complementary instruments, including the Intermediate Water Cherenkov Detector (IWCD). As a near detector, IWCD plays a critical role in constraining systematic uncertainties in the neutrino beam, characterizing neutrino interactions at different off-axis angles, and validating analysis and calibration techniques. These next-generation water-Cherenkov detectors together form an integrated experimental program aimed at addressing some of the most compelling open questions in particle physics.
We are seeking a highly motivated Ph.D. candidate to join our international research team and contribute to the development of these water-Cherenkov neutrino detectors. The position involves hands-on work with radioactive calibration sources, studies of particle discrimination techniques, and the application of machine learning methods to improve event classification and reconstruction.The candidate will gain extensive experience in both hardware and software aspects of neutrino experiments, including detector operation, simulation, and data analysis. They will work in close collaboration with other Spanish researchers and will actively participate in Hyper-K collaboration meetings and detector shifts, fostering their integration into the international neutrino physics community.

Candidates should have experience in data analysis and event reconstruction on particle physics or neutrino experiments. Programming languages such as Python or C++ is required. Simulation tools like GEANT4 would be highly considered. The ability to work both independently and as part of a collaborative, international research team is crucial.

• Contract duration: 1 year (possibility to extend up to 4 years)
• Estimated annual gross salary: Salary is commensurate with qualifications and consistent with our pay scales
• Target start date: 2025/10/01

We provide a highly stimulating research environment, and unique professional career development opportunities.

We offer and promote a diverse and inclusive environment and welcomes applicants regardless of age, disability, gender, nationality, ethnicity, religion, sexual orientation or gender identity.

The neutrino group at the DIPC (https://neutrino.dipc.org/) is dedicated to exploring fundamental questions in particle physics, particularly focusing on the elusive neutrino. Their research aims to understand the origin of matter by investigating rare processes. On top of its contribution on water-Cherenkov detectors, the team leads the NEXT (Neutrino Experiment with a Xenon TPC) collaboration, an international effort searching for neutrinoless double beta decay using high-pressure xenon gas time projection chambers. Additionally, the group is involved in developing innovative detection technologies, such as the PETALO project, which aims to enhance Positron Emission Tomography (PET) imaging. They are also contributing to neutrino research at the European Spallation Source (ESS). The DIPC neutrino group comprises physicists and engineers with expertise in particle detection, data analysis, and instrumentation. Their collaborative approach and involvement in cutting-edge experiments position them at the forefront of neutrino research.

Interested candidates should submit an updated CV and a brief statement of interest to the following application email below. 

Reference letters are welcome but not indispensable.

The reference of the specific opening to which the candidate is applying should be stated in the subject line, and the application must be received before the application deadline.

Although candidates are welcome to contact the project supervisors to know further details about the proposed research activity, please be aware that the application will be evaluated only if it is submitted directly to the email address listed below as application email.

• Reference: 2025/51
• Application deadline: 2025/09/12
• Application email: jobs.research@dipc.org

Applications received by the deadline will be evaluated by a Committee designed by the DIPC board on the basis of the following criteria:

• CV of the candidate (60%)
• Adequacy of the candidate’s scientific background to the project (20%)
• Reference letters (10%)
• Other: Diversity in gender, race, nationality, etc. (10%)

Evaluation results will be communicated to the candidates soon after. Positions will only be filled if qualified candidates are found.

The DIPC may revoke its decision if the candidate fails to join by the appointed time, in which case the position will be awarded to the candidate with the next highest score, provided it is above 50 (out of 100).

However, the selected candidate may keep the position if, in the opinion of the Selection Committee, the candidate duly justifies the reasons why he or she cannot join before the specified deadline, and as long as the project allows it.
