System Validation Engineer – PCB & Electro-Optics

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
