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 the hardware-in-the-loop (HIL) benches, automated test suites, and fault-injection campaigns that catch defects before they reach fielded hardware — and turn field and test data back into regression coverage. You focus on firmware behavior, fault handling, and system-level robustness rather than structural or environmental qualification.
This is a high-ownership role bridging embedded SW, hardware, and test automation. You partner with firmware, electrical, and systems engineers on fault management, verification, and bring-up of new boards.
What you'll do
- Design and build automated HIL (and SIL) test benches - combining real target hardware, simulation, and custom fixtures - to validate firmware under realistic and worst-case conditions.
- Own firmware regression as a reliability gate: integrate test suites into CI/CD so every change is automatically exercised on hardware.
- Design and run fault-injection campaigns (sensor faults, bus dropouts, power anomalies, motor-out) and verify the firmware's fault-management and safety-interlock responses.
- Build test tooling and instrumentation: signal injection, bus (CAN/UART/I2C/SPI) traffic generation and monitoring, telemetry capture, and automated log analysis.
- Turn flight-test and field data into a test-site-as-regression framework — reproduce in-service issues (including on third-party platforms) on the bench and lock them down with tests.
- Contribute to DFMEA and root-cause investigations from the firmware side; drive corrective actions and track firmware reliability metrics.
- Contribute to manufacturing / bring-up test suites for new boards and subsystems.
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 and instrumenting Embedded SW.
- Hands-on experience testing bare-metal or RTOS firmware on ARM Cortex-M microcontrollers (STM32 or similar); understanding of interrupts, timing, and clock-level behavior.
- Experience building or operating hardware-in-the-loop test setups.
- Comfortable with lab instruments: oscilloscopes, logic analyzers, power supplies, debuggers/JTAG-SWD (e.g. pyOCD, OpenOCD, J-Link).
- 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 (devicetree, Kconfig, west) or a comparable RTOS.
- Reliability methods: DFMEA, fault-tree/RBD analysis, root-cause, reliability metrics.
- Safety-critical or regulated-domain testing (aviation/UAS, automotive, medical); familiarity with standards (DO-178/DO-160, MIL-STD).
- Battery management (BMS), motor control, or power-electronics test experience.
