Post-Doctoral Researcher - Superconducting Quantum Sensors for Neutrino Physics, Dark Matter, and Rare Isotopes at Colorado School of Mines

Job description

Engineering a world of possibilities Postdoctoral Researcher – Colorado School of Mines Superconducting Quantum Sensors for Neutrino Physics, Dark Matter, and Rare Isotopes THE OPPORTUNITY The Quantum Technologies at the Sensitivity Frontier (QTSF) group at the Colorado School of Mines, led by Prof. Wouter Van De Pontseele, is hiring a post-doctoral researcher to develop superconducting sensors and scalable cryogenic readout for neutrino and dark matter experiments. The postdoc will lead one or two research thrusts. Sensor fabrication is handled by NIST and other partner institutions, so the work centers on characterization, readout, and integration into experiments. The position has guaranteed funding for two years, starting in January 2027. Extension beyond that is possible, subject to funding and performance. ABOUT THE GROUP QTSF (qtsf.mines.edu) develops quantum sensors to search for physics Beyond the Standard Model. The group has five PhD students and works closely with several faculty in Mines’ Quantum Engineering program. Current involvement: BeEST : precision studies of radioactive isotopes with eV-scale superconducting sensors. RICOCHET : coherent elastic neutrino-nucleus scattering (CEvNS) at the ILL reactor in Grenoble, France. Project 8 : a direct neutrino mass measurement using Cyclotron Radiation Emission Spectroscopy. Dark matter : demonstrator experiments for dark matter searches. CURIE : the Colorado Underground Research Institute, Mines’ underground laboratory. PRIMARY RESPONSIBILITIES Characterize superconducting tunnel junctions (STJs) and transition-edge sensors (TESs), including sub-eV sensors, and integrate them into cryogenic experiments. Develop microwave SQUID multiplexing and RFSoC-based readout with bandwidths above 100 kHz for scalable cryogenic experiments. Operate the group’s dilution refrigerator. Collaborate actively with NIST Boulder’s Quantum Sensors and Advanced Microwave Photonics groups, meeting at least monthly. Collaborate with PNNL, LLNL, Yale, MIT, Northwestern, and UC Berkeley, with occasional travel within the US and to France. Mentor PhD students and Quantum Engineering master’s students. Publish results and present them at conferences and seminars. The position prepares candidates for careers in academia, national laboratories, or industry. It includes teaching opportunities in Mines’ Quantum Engineering program and access to partners through the Elevate Quantum regional ecosystem. MINIMUM QUALIFICATIONS A PhD in Physics, Quantum Engineering, or Electrical Engineering. PREFERRED QUALIFICATIONS Experience with superconducting sensors (e.g., STJs, TESs, MMCs, KIDs) or other cryogenic detectors. Experience with SQUID or microwave SQUID multiplexed readout. Experience with dilution refrigerators, vector network analyzers, or RFSoC platforms (e.g., QICK). Knowledge of low-background techniques or low-threshold detector development. Bonus: sensor packaging and wirebonding, or microwave and electromagnetic simulation (e.g., HFSS, SONNET, COMSOL). HOW TO APPLY Applications are reviewed on a rolling basis until the position is filled. Complete an online application (personal information, demographic information, veteran status): A CV with a publication list. A cover letter of up to two pages describing your experience and which parts of the program interest you most. Contact details for three professional references.
