Staff /Sr. Staff Test Platform & Firmware Integration Engineer

Originally posted 11 November 2026 by the employer.

About the role

This role involves bringing up and operating firmware on System Level Test (SLT) boards and platforms for high-speed optical interconnect products. You will own the firmware layer for test, architect the test executive and datalog, and drive test flows from engineering bring-up through board-level test and manufacturing transfer.

What you'll do

• Own firmware bring-up and integration on SLT boards, covering boot and image management across board variants, device initialization, diagnostic APIs, register-level access, and mode and state control.
• Validate firmware releases against test requirements and resolve interface gaps with the firmware engineering team.
• Manage board-level functional test integration for assembled photonic boards, including firmware loading, calibration, device programming, pass/fail limits, and dry-run controls for irreversible operations.
• Architect and develop the SLT test executive, featuring configuration-driven test sequences, instrument and device abstraction, safe-state handling on abort, and unit-traceable datalogs.
• Implement continuous regression on bench hardware with scheduled runs, version-controlled sequences, and automated change detection across firmware and test content.
• Lead root-cause analysis of intermittent and order-dependent test failures, isolating test software, firmware, and hardware issues.

What you'll need

• Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field with 8+ years of relevant experience.
• Hands-on platform bring-up experience on embedded Linux hardware, including bootloader, kernel, boot-source and strap configuration, flash and memory initialization, console, JTAG, and logs.
• Experience validating firmware features across releases, including image management, upgrade and recovery, secure boot, warm restart, and state preservation.
• Experience building a hardware test automation framework from scratch and driving it to adoption for daily regression.
• Hardware-in-the-loop test experience with devices under test, test fixtures, instrumentation, fault injection, and negative testing.
• Strong Python scripting skills for test automation, along with proficiency in Linux command line, Git, and CI-integrated execution.
• Demonstrated ability to derive test coverage from schematics and firmware interface specifications for UART, I2C, SPI, and flash interfaces.
• Experience taking hardware products through NPI gates (EVT, DVT, PVT) with ownership of test readiness.

Nice to have

• Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field with 6+ years of industry experience.
• Experience with serial-link or network-port validation, including link state, lane configuration, link flaps across restarts, and port counters.
• Experience with telemetry and log pipelines for device diagnostics.
• Experience with factory or contract-manufacturer test handoff and sustaining.
• Exposure to optical, RF, or high-speed electrical measurement and instrument control.
• Experience with eFUSE or OTP programming controls and irreversible test steps.
