• 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. 

• →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 

• 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 

• 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
