Job summary

Lyte is seeking a hands-on Electrical Engineer to own system-level bringup for a complex electro-optical hardware platform. You will isolate issues to subsystems, debug analog circuits, and validate chip-to-board communication in a lab-centric role.

The position emphasizes Python-based test automation, rigorous failure analysis, and collaboration with offshore manufacturing partners to ensure robust production testing.

Qualifications

• Hands-on lab experience in PCB bringup and system validation.
• Strong analog circuit knowledge and debugging instincts at the bench.
• Experience with opto-electronic debug and mixed-signal interfaces.
• Fluency reading schematics, layouts, and datasheets.

Responsibilities

• Lead PCB and system-level bringup from first power-on to functional validation.
• Isolate failures in complex mixed-signal hardware and subsystems.
• Debug hardware/firmware interactions and analytic behavior with lab tools.
• Perform SI/PI measurements and localize noise sources.
• Drive failure analysis for prototype and production units and implement corrective actions.
• Validate chip-to-board communication (I2C, SPI, UART, GPIO).
• Build test plans with pass/fail criteria and Python automation for lab/testing.

Job description

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
• 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
• ~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

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
