Key Responsibilities

Cryo-mechanical fridge upgrades

• Install and rework cryo-mechanical hardware associated with fridge upgrades, including mechanical interfaces, shields, plates, brackets, harness routing supports, vacuum components, and integration fixtures.
• Execute defined fridge upgrade procedures and capture build records, configuration changes, deviations, and lessons learned for future upgrade campaigns.
• Support early bring-up and validation of upgraded fridge configurations under engineering guidance, including mechanical fit checks, thermal anchoring reviews, leak-check readiness, and cooldown preparation.

Lab Operations

• Operate lab tools and equipment in accordance with ESD and safety requirements
• Maintain clean, organized lab workspaces
• Track work performed, materials used, and results

Debug & Collaboration

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