Engineer, System Calibration

Job Description

Job Title: Senior Engineer, System Calibration. Location: Milpitas, California, United States

Responsibilities:

• Lead and organize all system-level calibration activities for prototype modules that scale into a fault-tolerant quantum computer.
• Aggregate calibration and operational data from component and subsystem teams into a unified system framework.
• Perform system-level risk analysis and develop mitigation plans across hardware, firmware, and software interfaces.
• Develop modeling and analytical tools to understand how calibrations interact across integrated subsystems;
• Track calibration timing, uptime estimates, and performance metrics to improve system reliability.
• Define requirements for hardware, firmware, and software teams to meet uptime and performance targets.
• Specify and validate test requirements across different levels of integration testing.
• Lead cross-functional working groups to address high-risk calibration challenges.
• Collaborate with control software teams to integrate calibrations into executable routines;
• Support debugging, root-cause analysis, and validation during system prototyping and integration.
• Work with technologies such as RF electronics, active photonics, analog mixed-signal hardware, lasers, cryostats, embedded systems, complex data acquisition systems, and quantum modules.
