Postdoctoral Researcher – Superconducting Detector Development and CMB Instrumentation

Position Overview

Argonne National Laboratory invites applications for a Postdoctoral Researcher position in Superconducting Detector Development and CMB Instrumentation. The role focuses on advancing large arrays of Transition Edge Sensor (TES) bolometers for studies of the Cosmic Microwave Background (CMB) while supporting exploration of novel applications for superconducting detectors.

The primary focus is to design, fabricate, characterize, integrate, and deploy superconducting detectors and devices for a multidisciplinary team developing advanced instrumentation for CMB measurements at remote sites, including the South Pole. The position also offers opportunities to investigate new materials and superconducting device concepts for applications in dark‑matter detection, neutrino measurements, millimeter‑wave line‑intensity mapping surveys, and quantum sensing.

The postdoctoral researcher will join a highly collaborative team of physicists and engineers across Argonne’s High Energy Physics (HEP) and Materials Science Division (MSD), working closely with partners at universities and national laboratories. The team’s expertise spans:

• Superconducting detector arrays
• Thin‑film materials development
• Nanofabrication
• Cryogenic instrumentation and measurements
• Large‑array development and deployment

This work is supported by Argonne’s world‑class research infrastructure, including:

• Dilution refrigerators
• Adiabatic demagnetization refrigerators
• Low‑noise DC and RF measurement systems
• Cleanroom fabrication facilities
• Access to the Center for Nanoscale Materials (CNM)

• Recent or soon‑to‑be completed PhD (within the last 0‑5 years) in physics, electrical engineering, materials science, or a closely related field.
• Experience in the development and/or deployment of superconducting devices, or related technologies in quantum devices, low‑temperature systems, microelectronics, or nanoelectronics.
• Experience in one or both of the following areas:
  • Design and fabrication of superconducting or related devices.
  • Low‑noise cryogenic measurement techniques at millikelvin to few‑kelvin temperatures for device characterization.
• Ability to model and support Argonne’s core values of impact, safety, respect, integrity, and teamwork.

• Experience with transition‑edge sensors (TESs) or kinetic inductance detectors (KIDs).
• Cleanroom microfabrication processes, including: thin‑film deposition (e.g., magnetron sputtering), electron‑beam or optical lithography, dry and wet etching.
• Microwave resonator design and characterization. RF and microwave measurement techniques.

The expected hiring range for this position is $72,879.00–$. The selected candidate will receive comprehensive benefits as part of Argonne’s total rewards package.
