Intern Software Development Engineer In Test Jobs in Chelsea, MI

Senior Integration Test Engineers serve as key stakeholders in the R&D process. This role bridges simulation and on-road testing by validating vehicle system behavior in a controlled lab environment. Senior Integration Test Engineers will focus on both static vehicle-level and HIL testing, replaying real-world drive logs, and documenting system responses. This role is unique in which you will lead testing on HIL bench test setups in addition to static vehicle-level simulated driving. 

As a Senior HIL Test Engineer, you will work closely with software, hardware, and systems engineers to architect the HIL infrastructure, pioneer new automation processes, and mentor the team in validating safety-critical systems in a fast-paced R&D environment.

• Lead the development and execution of comprehensive HIL test plans, focusing on the integration of autonomous software with autonomous system hardware
• Perform bench-level testing of sensors and compute modules
• Execute static vehicle-level HIL testing by simulating real-world driving scenarios in a controlled environment
• Execute structured test plans covering functional, regression, and fault-injection scenarios
• Measure and analyze software performance (latency, CPU/memory utilization, throughput) on target hardware to ensure the autonomy stack meets necessary requirements
• Design and implement automated test suites. Integrate HIL test results and automation workflows with cloud computing services (AWS) for scalable data analysis and regression tracking
• Monitor and debug vehicle communications
• Partner with Autonomy and Systems Engineering teams to define validation requirements and translate complex edge cases into repeatable HIL test cases.
• Ensure all anomalies are thoroughly documented. Champion product quality by contributing to acceptance criteria and safety-critical validation metrics

• Proven ability to construct and maintain HIL test environments
• Static vehicle-level or chassis dynamometer test experience
• Deep understanding of CAN networks and vehicle communication protocols
• Proficiency with Ethernet protocols (UDP and TCP) 
• Experience with CAN bus analysis tools (e.g., Intrepid Vehicle Spy, Vector CANoe/CANalyzer)
• Strong command of Linux environments for system configuration, log manipulation, and troubleshooting
• Expertise in Test Case Automation and scripting to reduce manual testing overhead
• Ability to prioritize complex deliverables and pivot testing strategies as autonomy software evolves
• Strong ability to translate low-level hardware bugs into actionable insights for high-level software teams
• Experience integrating test automation with cloud computing services (AWS)

Required

• Bachelor's degree in an applicable engineering field
• 5+ years experience testing complex safety-critical systems involving software, firmware, and/or hardware, preferably in an automotive context
• Direct experience with Hardware-in-the-Loop testing and system-level validation
• Valid driver's license and clear driving record

Desirable

• Master's degree in an applicable engineering field
• Experience testing ADAS vehicles or autonomous robotic systems
• Cloud Operations: Experience using AWS for data storage, compute, or CI/CD integration
• Coding: Proficiency in Python or C++ for creating test scripts and data analysis tools

• Standard office working conditions which includes but is not limited to:
• Prolonged sitting
• Prolonged standing
• Prolonged computer use
• Travel required? -  Low: 0%-10%
