Senior Systems Integration Engineer, Hardware-in-the-Loop (HIL)

About the role

We are seeking a Senior Systems Integration Engineer to develop and maintain the hardware-in-the-loop (HIL) test benches used to validate our autonomy stack off-vehicle. In this role, you will be responsible for building, instrumenting, and commissioning physical test benches, implementing automation scripts, and supporting daily execution for our software and autonomy teams. This is a deeply hands-on role where you will assemble and wire bench hardware, integrate interface tooling, write reliable test automation, and maintain clear documentation and troubleshooting guides.

What you'll do

• System Bench Design & Fabrication: Design, build, and commission hardware-in-the-loop (HIL) test benches, including schematic capture, component selection, harness fabrication, and mechanical layout. Validate and document correlations between bench and vehicle behavior, noting any hardware fidelity limits or test divergences.
• Vehicle & Network Simulation: Implement vehicle bus and controller simulations across CAN, CAN-FD, and Automotive Ethernet so autonomy compute interacts with complete simulated systems. Set up power/ignition sequencing, drive-by-wire responses, and gateway override interfaces to command specific vehicle test states.
• Sensor Data Replay: Implement and maintain open-loop sensor and telemetry data replay into compute hardware at full rate and time-synchronized to original log timestamps. Assist with integrating interfaces and data pipelines to support repeatable bench testing and future closed-loop test capabilities.
• Test Automation & CI Integration: Develop and maintain automated test scripts and execution pipelines that trigger bench tests from code commits, support release regression testing, run unattended, and generate clear pass/fail test reports.
• Fault Injection & Safety Validation: Implement and execute fault-injection tests-including power loss, communication drops, and degraded-mode behaviors-to validate failsafe handling against safety requirements.
• Vendor & Equipment Coordination: Evaluate, bring up, and maintain commercial bench hardware and software tools. Coordinate with vendors and suppliers on lead times, component orders, and toolchain updates.
• Cross-Functional Triage & Debugging: Support autonomy, software, and hardware engineers using the bench by maintaining bench uptime and tracking issues. Debug bench failures across sensor timing, harnesses, drivers, and compute, documenting root causes and collaborating with engineering teams on fixes.
• Documentation & Best Practices: Maintain comprehensive bench schematics, harness drawings, wire labeling, and operating guides. Train engineers and technicians on bench operation and standard troubleshooting procedures.

What we're looking for

• Education & Experience: Bachelor's in EE, CE, ME, CS, or related field with 5+ years of experience.
• HIL & Bench Build: Proven track record building, wiring, and commissioning HIL benches, including schematic review, component sourcing, harness fabrication, and bring-up.
• Vehicle Networks: Hands-on experience with CAN, CAN-FD, LIN, and Automotive Ethernet, including restbus simulation, DBC/LDF editing, and bus analysis tools (e.g., Vector CANoe, PCAN, Wireshark).
• Plant & Sensor Modeling: Experience configuring and deploying real-time plant, actuator, sensor, or power models onto real-time target hardware (e.g., Speedgoat, dSPACE, NI).
• Software & Automation: Strong Python for test automation, working familiarity with C/C++ in Linux, and experience integrating test suites into CI pipelines.
• Robotics Middleware & Interfaces: Practical familiarity with ROS/ROS2 (logging, rosbag, replay), high-speed camera links (GMSL/FPD-Link), lidar/radar interfaces, and PTP/gPTP synchronization.
• Fault Injection & Safety: Hands-on execution of fault injection and off-nominal testing (frame drops, signal loss, degraded sensors, power cuts) against safety requirements.
• Execution & Communication: Ability to deliver in fast-moving, evolving hardware/software environments, paired with clear documentation skills for wiring schematics, test procedures, and debug logs.
