System Validation Engineer – PCB & Electro-Optics

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 on cutting-edge technologies with a highly cross-functional team About Lyte Lyte builds perception systems for Physical AI operating in complex environments. The company combines custom silicon, integrated sensors, and software into a unified platform for robotics, mobility, and next-generation automation. Lyte is headquartered in Sunnyvale, California, with a global presence.
