Validation Engineer, Cryogenic

Job Description

Job Title: Validation Engineer – Cryogenic Systems. Location: Milpitas, California, United States

PsiQuantum is on a mission to build the world’s first utility-scale, fault-tolerant quantum computer using silicon photonics. As a Cryogenic Validation Engineer, you’ll play a critical role in validating electro-optical assemblies in cryogenic environments; helping us bridge the gap between advanced quantum hardware design and reliable system performance.

Responsibilities:

  • Develop and implement characterization methods for cryogenic electro-optical assemblies.
  • Collaborate closely with design and experimental teams to refine and validate design concepts.
  • Define performance metrics and design validation strategies for cryogenic systems.
  • Build and manage lab setups using cryogenic equipment, light sources, detectors, oscilloscopes, switches, and other instrumentation.
  • Develop automation scripts to run measurement sequences and store results in databases.
  • Assist in creating algorithms for data analysis and performance extraction.
  • Execute validation plans and troubleshoot hardware behavior in cryogenic environments.

Qualifications:

  • Bachelor’s or higher degree in Engineering, Physics, or Materials Science.
  • Minimum 3 years of experience in a related industry role.
  • Hands-on experience with cryogenic test environments.
  • Skilled in operating lasers, OSAs, VNAs, AWGs, and other optical/electrical test tools.
  • Experience with photonic integrated circuits or single-photon detectors is a plus.
  • Proficiency in scripting (e.g., Python) for automating test equipment and data handling.
  • Strong analytical skills to develop tuning, calibration, and performance analysis algorithms.

Compensation:

  • U.S. Base Salary Range: $120,000 – $150,000 USD
  • Bay Area Range: $145,000 – $170,000 USD
