Hardware-in-the-Loop (HIL) Software/Firmware Engineer

You will...

• Develop the software and firmware that powers Waabi's HIL benches - test runners, simulation/stimulation interfaces, fault-injection tooling, and bench control software.
• Build simulation interfaces that feed synthetic vehicle dynamics (pose, speed, sensor data) to embedded modules under test, and stimulation tooling that injects CAN/Ethernet messages to trigger logical state changes.
• Implement automated test frameworks and scripts to run requirement-based tests (timing, fault handling, mode transitions, disengagements) on real hardware.
• Integrate HIL test execution into CI so firmware and software releases are automatically validated on benches before reaching the vehicle, including test-modality tracking and result reporting.
• Develop instrumentation and data acquisition software for hardware timestamping, analog measurement triggers, and endurance-run analysis.
• Work hands-on at the bench: bring up new bench configurations, debug hardware/software interactions, and support engineers across Embedded, Autonomy, and V&V running tests on HIL.
• Analyze and document test data for hardware, autonomy, and systems engineering teams.

Qualifications:

• Bachelor of Science in Computer Science, Computer Engineering, Electrical Engineering, or equivalent industry experience.
• 4+ years of experience developing software for HIL, embedded test automation, or real-time test systems.
• Strong programming skills in Python; working proficiency in C/C++/Rust for embedded or real-time contexts.
• Hands-on experience with automotive communication interfaces - CAN, automotive Ethernet - including message injection, logging, and debugging (e.g., CANalyzer, python-can, SocketCAN).
• Experience building test automation frameworks and integrating hardware tests into CI pipelines.
• Comfortable working with lab equipment (oscilloscopes, DAQs, power supplies, E-loads) and debugging at the hardware/software boundary.
• Strong Linux proficiency for command-line workflows, system utilities, and bench infrastructure.
• Excellent technical writing skills for effective communication and documentation.
• Passionate about self-driving technologies, solving hard problems, and creating innovative solutions.

Bonus:

• Experience with real-time operating systems (RTOS) and real-time Linux.
• Experience with plant modeling and vehicle dynamics simulation (MATLAB/Simulink, dSPACE ASM, CarSim, or custom).
• Familiarity with functional safety standards (ISO 26262) and safety MCU architectures.
• Experience with GUI or dashboard development for test operators (PyQt, web-based tooling).
• Firmware development experience on automotive microcontrollers.
