Cyro-Mechanical Lab Engineer

Job Description

We are seeking a hands-on cryo-mechanical lab engineer to support dilution refrigerator upgrades, retrofit integration, and sustaining improvements across quantum hardware systems. This role is focused on executing well-documented mechanical upgrades in active lab environments, improving repeatability of fridge configuration changes, and collaborating closely with cryogenic systems, packaging, facilities, and test engineers.

\n

Debug & Collaboration

\n

\n
• Identify mechanical fit, thermalization, vacuum, routing, contamination, or configuration issues during upgrade execution and escalate with supporting data.
\n
• Capture photos, measurements, torque records, configuration notes, and observations to support upgrade debug, engineering review, and future procedure improvements.
\n
• Work closely with internal engineers while owning day‑to‑day execution
