Job Description

Job Title: Senior Electronics Systems Integration & Validation Engineer. Location: Milpitas, California, USA

Responsibilities:

• Lead the integration, bring-up, verification, and validation of complex electronic, embedded software, firmware, FPGA, and control subsystems for photonic quantum computing platforms.
• Define and execute system integration, verification, and test strategies, including acceptance criteria, validation methods, and automated test frameworks.
• Develop and execute system-level test plans with Optical, Software, and Quantum Engineering teams.
• Verify and validate hardware, firmware, software, detector readout, data acquisition, timing, and control interfaces.
• Integrate and validate single-photon detector readout, high-speed digitizers, photonic integrated circuit (PIC) multiplexing systems, timing and synchronization electronics, and data acquisition subsystems;
• Lead root-cause investigations and technical problem solving through structured, data-driven debugging across hardware, firmware, software, and control interfaces.
• Validate hardware, firmware, and embedded software releases.
• Develop diagnostics, health-monitoring tools, and automation to improve integration efficiency, test coverage, and system reliability.
• Develop and maintain integration procedures, validation protocols, work instructions, and technical documentation for manufacturing, deployment, and field support.
• Collaborate with Software, Firmware, Electronics, Optical, and Test Engineering teams to resolve integration issues and improve system performance.
• Mentor junior engineers and provide technical leadership during integration and validation activities.
• Drive continuous improvement of system integration, verification, and testing methodologies.

Qualifications:

• M.S. or Ph.D. in Electrical Engineering, Computer Engineering, Computer Science, or a related technical field with 5+ years of relevant industry experience, or B.S. with 10+ years of relevant industry experience.
• Demonstrated experience integrating, verifying, validating, and troubleshooting complex electronic systems involving embedded software, firmware, FPGA-based systems, instrumentation, and control systems.
• Experience with system integration, verification, validation, factory acceptance testing (FAT), site acceptance testing (SAT), production bring-up, and structured root-cause analysis;
• Hands-on experience with high-speed digitizers, detector readout systems, data acquisition systems, timing and synchronization electronics, FPGA-based instrumentation, or comparable high-performance electronic measurement and test platforms.
• Strong understanding of hardware/software interfaces, communication protocols, and system-level debugging.
• Proficiency in Python or similar scripting languages for test automation, diagnostics, instrumentation control, and data analysis.
• Ability to interpret electrical schematics, FPGA interface documentation, system architecture diagrams, and engineering specifications.
• Strong analytical, communication, and cross-functional collaboration skills.
• Ability to lead technical investigations and make engineering decisions in a fast-paced development environment.

Preferred:

• Experience with photonic integrated circuits (PICs).
• Experience with single-photon detector systems.
• Experience with laser and fiber-optic systems.
• Experience with cryogenic instrumentation.
• Experience with quantum technologies.
