Job summary

Lyte in Sunnyvale, CA, is seeking a hands-on hardware engineer to own system-level bringup and debug of complex electro-optical hardware. You will isolate failures, validate mixed-signal blocks, and drive corrective actions from prototype to production.

Responsibilities include board bringup, signal integrity measurements, Python automation for lab tests, and collaboration with offshore manufacturing partners to ensure robust production validation.

Qualifications

• BS/MS/PhD in Electrical Engineering from a top research university.
• ~5 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.

Responsibilities

• 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.

Ifyou’reexcited about building impactful technology in a dynamic, hands-on environment,we’dlove to hear from you!

About the role

• We are looking for a hands-on, lab-centric person to own 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

• 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
• Experience with embedded microcontrollers, SoCs, and FPGAs
• 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
