Responsibilities

Own firmware bring-up and integration on system-level test boards, including boot and image management, device initialization, diagnostic APIs, register access, and state control.
Validate firmware releases and coordinate closure of testability gaps with firmware teams.
Own board-level functional-test integration, including firmware loading, calibration and programming content, pass/fail limits, retest policy, and safe controls for irreversible operations.
Architect and build a configuration-driven test executive with device and instrument abstraction, safe-state abort handling, and comprehensive datalogging.
Build and operate continuous regression on bench hardware with scheduled runs, change detection, versioned test sequences, and reproducible production flows.
Lead root-cause analysis of intermittent and order-dependent failures across test software, firmware, and hardware.
Create operator procedures, test plans, release documentation, and manufacturing transfer packages.
Set software-development practices for the team and mentor early-career engineers in test automation, code review, and documentation.

Requirements

Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field with 8+ years of relevant experience.
Hands-on embedded Linux platform bring-up experience, including boot sequences, boot-source and strap configuration, flash and memory initialization, bootloaders, kernels, console debugging, JTAG, and logs.
Experience validating firmware-level features across releases, including image management, upgrades, recovery, secure boot, warm restart, and state preservation.
Experience building a hardware-product test automation framework from the ground up and driving it into daily team or organizational regression use.
Hardware-in-the-loop testing with real devices, fixtures, and instruments, including fault injection and negative testing.
Strong Python scripting skills for test automation and comfort with Linux command-line tools, Git, and CI-integrated test execution.
Ability to derive test coverage from schematics and firmware interface specifications for UART, I2C, SPI, and flash interfaces.
Experience shipping hardware products through EVT, DVT, and PVT gates with ownership of test readiness.
Preferred: master’s degree with 6+ years of industry experience; serial-link or network-port validation; telemetry and diagnostic log pipelines; factory or contract-manufacturer test handoff; optical, RF, or high-speed electrical measurement; and eFUSE, OTP, or other irreversible test controls.
