Senior Engineer, System Calibration (Electro-Optics)

Job Summary

PsiQuantum’s mission is to build the first useful quantum computers. This role focuses on developing and testing prototype modules that will scale into a datacenter-sized, fault-tolerant quantum computer. These modules and subsystems require regular calibration to ensure reliable generation of single photons and entangled states.

Responsibilities

• System Calibration Strategy

• Consolidate and structure all calibration and operational information for our components and sub-assemblies involving electro-optic devices
• Lead system-level calibration risk analysis and mitigation planning across hardware, firmware, and software interfaces
• Develop requirements for hardware, firmware, and software teams to meet uptime and performance targets
• Own and optimize calibration strategy against uptime requirements

• Modeling & Analysis

• Develop modeling and analytical tools to understand how component-level electro-optic calibrations behave and interact when integrated into the full system
• Track calibration time estimates and actuals to model our system’s uptime and identify areas requiring optimization

• Integration & Execution

• Conduct prototyping of calibrations on benchtop setups
• Specify test requirements to validate and de-risk calibrations at various levels of integration testing
• Write control software to implement calibration procedures in our software stack

• Cross-Functional Leadership

• Lead ad-hoc cross-functional working groups to collaboratively develop and refine high-risk calibrations
• Partner with other system calibration engineers and software engineering teams to integrate calibrations into executable routines
• Lead system-level validation support by providing system-level context, debugging support, and root-cause analysis during prototyping and integration

Qualifications

• M.S. with 5+ years of industry experience or Ph.D. with 3+ years of industry experience in Electrical Engineering, Optical Engineering, Physics, or a related discipline
• Experience developing and integrating complex systems spanning optical and electronic hardware, firmware, software, and data acquisition, including cross-functional collaboration
• Hands-on experience designing, characterizing, or calibrating electro-optic devices and systems
• Experience developing and integrating complex systems across optical/electronic hardware, firmware, and software, including cross-functional collaboration
• Proven ability to translate complex technical concepts into clear requirements, models, or system frameworks
• Experience with integrated photonics, RF systems, or high-speed optical switching
• Experience developing or scaling calibration procedures in complex experimental or production systems where scale and high reliability matter
• Experience with system-level modeling, uptime analysis, or performance optimization
• Track record of leading cross-functional technical efforts or driving alignment across teams
• Demonstrated interest in quantum computing or related advanced technologies
