System Calibration (Electro-Optics)

Job Description

Job Title: Senior Engineer, System Calibration (Electro-Optics). Location: Milpitas, California, United States

Responsibilities:

• Own and drive the end-to-end calibration strategy for electro-optic subsystems, from early concept through system integration and deployment.
• Focus calibration strategies on system uptime, scalability, repeatability, and operational efficiency.
• Consolidate and structure calibration and operational information for 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 strategies against system uptime requirements.
• Develop modeling and analytical tools to understand how component-level electro-optic calibrations behave and interact when integrated into the full system.
• Track estimated and actual calibration times to model system uptime and identify areas requiring optimization.
• Prototype calibration procedures on benchtop setups.
• Specify test requirements to validate and de-risk calibrations at different levels of integration testing.
• Write control software to implement calibration procedures within the software stack.
• Lead ad-hoc cross-functional working groups to develop and refine high-risk calibration procedures;
• Work with other system calibration engineers and software engineering teams to integrate calibrations into executable routines.
• Provide system-level validation support, including system-level context, debugging, and root-cause analysis during prototyping and integration.
• Identify and de-risk critical calibration dependencies early in development.
• Reduce calibration time and minimize the impact of calibration on system uptime.
• Develop robust, automated calibration routines that integrate cleanly with the system software stack.
• Establish scalable calibration frameworks to support high-availability quantum computing systems.

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.
• Experience collaborating across multiple engineering disciplines and teams;
• Hands-on experience designing, characterizing, or calibrating electro-optic devices and systems.
• Proven ability to translate complex technical concepts into clear requirements, models, or system frameworks.
• Experience working across optical/electronic hardware, firmware, and software interfaces.
• Strong system-level problem-solving and analytical capabilities.

Preferred:

• Experience with integrated photonics, RF systems, or high-speed optical switching.
• Experience developing or scaling calibration procedures for complex experimental or production systems where scalability and high reliability are important.
• Experience with system-level modeling, uptime analysis, or performance optimization;
• Track record of leading cross-functional technical efforts or driving alignment across teams.
• Experience documenting system architectures, experimental processes, or hardware designs in a structured and scalable manner.
• Demonstrated interest in quantum computing or related advanced technologies.
