Job summary

Lyte is hiring for a hands-on, lab-centric role to own system-level bringup and debug of electro-optical hardware, including mixed-signal ASICs, photonics, DSPs, and power management ICs. You will isolate issues at the component level and drive corrective actions, with potential to grow into a module lead.

You will lead PCB/system bringup, debug analog behavior, and validate chip-to-board communication, while building test plans and Python automation for lab and production testing.

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.

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.
