Job Summary

We are seeking to hire a post-baccalaureate researcher to participate in SuperCDMS SNOLAB and / or our effort to develop phonon-mediated dark matter detectors using kinetic inductance detectors.

Essential Job Duties

Areas of work in the group include :

Commissioning, operations, and science analyses for SuperCDMS SNOLAB. Our group anticipates playing a significant role in the following areas :

Early science with the SuperCDMS SNOLAB detectors in the CUTE facility at SNOLAB.
Commissioning of the SuperCDMS SNOLAB cryostat.
Detector commissioning for SuperCDMS SNOLAB.
Science run operations and analysis, with a focus on profile-likelihood techniques for background subtraction for the SuperCDMS HV detectors.

Development of phonon-mediated dark matter detectors using kinetic inductance detectors (KIDs) and quantum capacitance detectors (QCDs).

In these detectors, phonons created by a particle interaction or drifting electron-hole pairs in a crystalline substrate are sensed using KIDs and / or QCDs, which offer excellent radio-frequency multiplex ability and, eventually, sensitivity to production of single phonons.

We are developing two architectures : a gram-scale format intended to achieve the lowest possible thresholds for sub-GeV nucleon-scattering dark matter and sub-MeV electron-scattering dark matter; and a 25-gram-scale format that will use drift phonon production to discriminate nuclear from electron recoils down to the production of single electron-hole pairs in order to reach the neutrino fog in the 0.5-5 GeV mass range.

Basic Qualifications

Applicants should have :

Completed or near completion of an undergraduate degree in astronomy, physics, applied physics, electrical engineering, materials science, or any other field relevant to the above work.

Experience in some (but not necessarily all) of the following areas : mechanical design using CAD software, electronics design, python coding, data analysis, sub-Kelvin cryogenics, sub-Kelvin cryogenic detectors, and / or superconducting qubit design / testing.

The ability to work independently, set priorities, and seek technical input from diverse sources.
