Electro-Optics System Validation Engineer – PCB Bringup

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.
