System Validation Engineer – PCB & Electro-Optics

Lyte; Sunnyvale (CA); On-site; USD 120,000 - 170,000; Full time

Job summary

Lyte in Sunnyvale, CA is seeking a hands-on engineer to own system-level bringup of electro-optical hardware. You will lead PCB and system validation from first power-on to functional verification, isolating issues to subsystems.

You’ll use oscilloscopes, spectrum analyzers, logic analyzers, and Python automation to debug mixed-signal ASICs, photonics, DSPs, and power management ICs. Collaboration with offshore manufacturing for validation and production tests will be part of the role.

Qualifications

• BS/MS/PhD in Electrical Engineering from a top research university.
• 3–6 years hands-on lab experience in PCB bringup, system validation, signal/power integrity, or failure analysis.
• Solid analog circuit knowledge – bias networks, LDOs, PLLs, ADCs/DACs, mixed-signal interfaces.
• Opto-electronic debug experience: optical power meters, photodetectors, spectrum analyzers.
• Python for test automation and data analysis.
• Fluent reading schematics, layout files, and datasheets.

Responsibilities

• Lead PCB and system-level bringup, first power-on through functional validation.
• Isolate failures in a complex system, localizing issues to subsystems.
• Debug hardware/firmware interactions and analog circuit behavior with test tools.
• Perform signal integrity and power integrity measurements; identify noise sources.
• Drive failure analysis on prototypes and production units; implement corrective actions.
• Validate chip-to-board communication (I2C, SPI, UART, GPIO).
• Build test plans with pass/fail criteria and Python automation for lab/production testing.
• Support offshore manufacturing partners on assembly validation, calibration, and production test.

Job description

About the role

• We are seeking a Hands-on, lab-centric role owning system-level bringup and debug of our electro-optical hardware – a complex system of mixed-signal ASICs, photonic modules, DSP chips, and power management ICs. Your core strength: methodically isolating problems and localizing them to a specific component or subsystem. Potential to grow into a module lead role.

What you’ll do

• Lead PCB and system-level bringup, first power-on through functional validation
• Isolate failures in a complex system of mixed-signal ASICs, photonics, DSP chips, and power management ICs, localizing each issue to a specific component or subsystem
• Debug hardware/firmware interactions and analog circuit behavior using oscilloscopes, logic analyzers, and spectrum analyzers
• Perform signal integrity and power integrity measurements; localize sources of noise and cross-talk
• Drive failure analysis on prototype and production units; turn findings into corrective actions
• Validate chip-to-board communication (I2C, SPI, UART, GPIO)
• Build test plans with clear pass/fail criteria and Python automation for lab and production testing
• Support offshore manufacturing partners on assembly validation, calibration, and production test

Required Qualifications

• BS, MS, or PhD in Electrical Engineering from a top research university
• 3–6 years of hands-on lab experience in PCB bringup, system validation, signal/power integrity, or failure analysis
• Solid analog circuit knowledge – bias networks, LDOs, PLLs, ADCs/DACs, mixed-signal interfaces – and the instincts to debug them at the bench
• Opto-electronic debug experience: optical power meters, photodetectors, spectrum analyzers
• Python for test automation and data analysis
• Fluent reading schematics, layout files, and datasheets

Preferred Qualifications

• Board-level work with SiP or ASIC platforms
• FPGA-based emulation platforms (Palladium, Zebu, VCS)
• Reliability testing (thermal cycling, HALT, HASS); taking products into mass production

Benefits (subject to location and local regulations)

• Competitive salary and equity
• Comprehensive medical, dental, and vision coverage
• 401(k) retirement plan
• Flexible vacation and time-off policy
• Collaborative, fast-paced, and inclusive work environment
• Opportunity to work oncutting-edgetechnologies with a highly cross-functional team
