Embedded SW Test Engineer
DoorDash USA · San Francisco, CA
About this role
## Embedded SW Test Engineer ### About the Role We are looking for an Embedded SW Test Engineer to own how we prove our Embedded SW is trustworthy. You will build hardware-in-the-loop (HIL) benches, automated test suites, and fault-injection campaigns that catch defects before they reach fielded hardware. This is a high-ownership role bridging embedded SW, hardware, and test automation. ### What You'll Do - Design and build automated HIL and SIL test benches combining real target hardware, simulation, and custom fixtures - Own firmware regression as a reliability gate; integrate test suites into CI/CD - Design and run fault-injection campaigns (sensor faults, bus dropouts, power anomalies, motor-out) - Build test tooling and instrumentation: signal injection, bus traffic generation/monitoring, telemetry capture - Turn flight-test and field data into a test-site-as-regression framework - Contribute to DFMEA and root-cause investigations; drive corrective actions - Contribute to manufacturing and bring-up test suites for new boards ### What We're Looking For - 8+ years in embedded software test, firmware verification, or embedded reliability engineering - Strong Python (test automation, tooling) and working C/C++ for reading/instrumenting Embedded SW - Hands-on experience testing bare-metal or RTOS firmware on ARM Cortex-M microcontrollers (STM32 or similar) - Experience building or operating hardware-in-the-loop test setups - Comfortable with lab instruments: oscilloscopes, logic analyzers, power supplies, debuggers/JTAG-SWD - Familiar with embedded buses/protocols: CAN/CAN-FD, UART, I2C, SPI - Git, CMake, and CI systems (GitHub Actions, Buildkite, or similar) - Schematic reading; comfort with a soldering iron - Thrive in a high-integrity, fast-paced, safety-critical engineering environment ### Nice to Have - Zephyr RTOS or comparable RTOS experience - Reliability methods: DFMEA, fault-tree/RBD analysis, root-cause, reliability metrics - Safety-critical or regulated-domain testing (aviation/UAS, automotive, medical) - Battery management, motor control, or power-electronics test experience ### Compensation **Base Salary Range:** $89,100 – $131,000 USD Compensation includes equity grant opportunities. Comprehensive benefits package includes 401(k) with employer matching, 16 weeks paid parental leave, wellness benefits, medical/dental/vision, 11 paid holidays, and more.
