The Role
We are seeking a motivated software engineer to help verify and validate Propulsion Thermal Management functions across virtual, simulated, hardware-in-the-loop, and vehicle environments. In this role, you will translate system requirements and behavioral specifications into clear, traceable test cases, develop and execute automated system behavior tests, analyze results, and support the resolution of issues that affect vehicle software quality.
The role is in the Vehicle Software and Electronics Engineering (VSEE) organization. The team is at the forefront of innovation, where vehicle software design, integration, release, and validation come together to improve engineering and quality processes. Your work will help ensure that thermal-management functions—including battery and propulsion-system temperature control, cabin conditioning, diagnostics, and degraded operating modes—perform as intended and support the delivery of high-quality GM vehicles. This work contributes to GM's vision of a world with ZERO Crashes, ZERO Emissions, and ZERO Congestion.
What You'll do
- Translate Propulsion Thermal Management system requirements, system functions, and Behavioral Test Specifications (BTS) into clear, traceable system test cases, procedures, and acceptance criteria. Maintain linkage between requirements, test assets, execution results, and defects.
- Develop, maintain, and execute automated System Behavior Tests (SBTs) and functional system tests for propulsion thermal functions across CoSim/SIL environments, with targeted validation on HIL benches and vehicles when real-time behavior, hardware I/O, or physical system response is required.
- Validate end-to-end thermal-management behavior, including RESS/battery heating and cooling, power-electronics and drive-unit thermal protection, cabin heating and cooling, thermal request coordination and arbitration, sensor and actuator behavior, diagnostics, and degraded or remedial operating modes.
- Support CoSim package readiness for Propulsion Thermal Management by checking package health, interfaces, configurations, virtual ECU behavior, plant-model connectivity, HWIO behavior, and environment sanity before broader regression or milestone testing.
- Review automated regression results. Rapidly distinguish product/software defects from CoSim, plant-model, infrastructure, configuration, or test-script issues; perform initial root-cause isolation and route each issue to the appropriate owner.
- Document failures with sufficient technical detail to reproduce the issue, including software and model versions, vehicle/environment conditions, calibrations or overrides, logs, expected versus actual behavior, and requirement/test-case references. Track defects through resolution and verify corrective actions through retest and regression.
- Partner with Product System Engineers, System Owners, Functional System Architects, System/Sub-System Engineers, Software Quality Assurance Engineers, Software Integration Managers, calibration teams, and validation teams to define test scope, review BTS/STS content, resolve requirement ambiguity, and support TFRP milestone readiness.
- Maintain test scripts, procedures, test data, dashboards, and supporting documentation for current software and CoSim releases. Share lessons learned, training materials, reusable test patterns, and best practices that improve consistency and reduce duplicated effort.
- Participate in product, architecture, model, and test-environment reviews; provide actionable feedback on testability, observability, requirement quality, system boundaries, and end-to-end verification strategy.
Required Qualifications
- Currently pursuing a Bachelor's or Master's degree in Mechanical Engineering, Mechatronics, Computer Engineering, Computer Science, Electrical Engineering, or a related field.
- Expected to graduate between December 2026 and June 2027.
- Available to work full-time, 40 hours per week.
Preferred Qualifications
- Knowledge of vehicle thermal-management systems, including refrigeration cycles, refrigerant systems, HVAC, heat pumps, and associated controls
- Experience with automated testing frameworks, such as Robot Framework or Autobot, for system-level validation and regression testing.
- Proficiency in programming or scripting using C, C++, Python, or comparable languages.
- Familiarity with Behavior-Driven Development (BDD) processes and Gherkin syntax.
- Experience using ETAS INCA, Intrepid Vehicle Spy, or similar data-acquisition and vehicle-network tools.
- Experience with MATLAB and Simulink for plant-model development and integration; basic familiarity with simulation tools such as GT-Power, Amesim, or CarSim.
- Familiarity with automotive communication technologies, including CAN, LIN, SPI, and automotive Ethernet.
- Experience with virtualization, software integration, or virtual ECU environments.
- Familiarity with visualization tools such as Power BI or Databricks dashboards to communicate technical insights effectively.
- Familiarity with SQL and Databricks in an Azure Cloud environment.
- Familiarity with data-storage solutions, databases, and data-processing frameworks.
- Ability to translate business or engineering questions into data-driven solutions.
- Experience developing or applying AI/ML-based solutions.
