Open position: Applied Physicist for lunar payload research & development

  • Dávid Lucsányi
  • -   7 March 2022

Puli Space Technologies Ltd. is extending its scientific R&D team, and looking for an Applied Physicist to work with us in full-time on R&D activities of the Puli Lunar Water Snooper (PLWS) instrument.

About PLWS

The Puli Lunar Water Snooper (PLWS), a lunar neutron spectrometer instrument is being developed by Puli Space Technologies to in-situ identify and measure the subsurface hydrogen (including water ice) content of the lunar regolith, addressing an essential need of the In-Situ Resource Utilization community and scientific goals of the NASA Artemis program. Low-energy albedo neutrons are scattering upwards and emerging from the lunar regolith due to high-energy cosmic rays, with a final neutron energy distribution characteristic to the local soil composition. PLWS detects these thermal and epithermal neutron fluxes using modified commercial off-the-shelf CMOS image sensors as neutron detectors. In the context of a NASA payload challenge, flight-ready prototype models have been already manufactured and delivered to NASA JPL in February 2022, and the first PLWS might be delivered to the Moon on a NASA CLPS mission in 2024. Neutron testing of the instrument is being performed at CERN in collaboration with CERN Radiation To Electronics (R2E) project, paving the way for terrestrial applications of the PLWS around high-energy particle accelerators, like the Large Hadron Collider (LHC).

Your main tasks

  • Performing Monte Carlo particle transport simulations
  • Analysis and post-processing of simulation and experimental data
  • Characterization of CMOS image sensor- and system-level detector responses
  • Supporting irradiation test campaigns of the instrument, for both lunar and terrestrial applications
  • Supporting engineering design of the instrument, for both lunar and terrestrial applications
  • Definition and validation of the payload concept of operation

Your profile

  • MSc in Physics, preferably specialized in either Nuclear Technology, Nuclear & Particle Physics or Medical Physics; or MSc in Nuclear Energy Engineering
  • Basic knowledge of Radiation-Matter Interactions, Monte Carlo Methods and Neutron Physics
  • Experience in Monte Carlo particle transport simulations, preferably with either FLUKA, Geant4 or MCNP
  • Experience in Data Analysis and Data Visualization
  • Good programming skills in an object-oriented language (Python, Matlab, C++)
  • Minimum one year relevant work experience
  • Fluency in English

We offer

  • Interdisciplinary challenges to solve
  • Innovative, cutting-edge technologies to work on
  • Competitive salary
  • Teamwork in a small, experienced and multidisciplinary team
  • Close collaboration with CERN, NASA, ESA and other partners
  • Opportunity to contribute directly to lunar exploration


Office and workshop of Puli Space is located at Sztregova u. 1., 1116 Budapest, Hungary. Partial remote working is possible.
