Job summary

Socket.dev is seeking a hands-on, lab-centric engineer to own system-level bringup and debugging of our electro-optical hardware—an intricate mix of mixed-signal ASICs, photonic modules, DSP chips, and PMICs. You will localize issues to specific subsystems and drive corrective actions.

You will lead PCB and system-level bringup from power-on through validation, perform SI/PI measurements, and develop Python automation for lab tests.

Qualifications

• BS/MS/PhD in Electrical Engineering from a top university.
• 3–6 years hands-on lab experience in PCB bringup, system validation, signal/power integrity or failure analysis.
• Strong analog circuit knowledge (bias networks, LDOs, PLLs, ADCs/DACs) with bench debugging instincts.
• Opto-electronic debug experience with optical power meters, photodetectors, spectrum analyzers.
• Python for test automation and data analysis.
• Fluent reading of schematics, layout files, and datasheets.

Responsibilities

• Lead PCB and system-level bringup, first power-on through functional validation.
• Isolate failures in complex mixed-signal systems and localize to a component or subsystem.
• Debug hardware/firmware interactions and analog circuit behavior with lab instruments.
• Perform signal integrity and power integrity measurements; identify noise and crosstalk sources.
• Drive failure analysis on prototypes and production units; implement 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.
