About the role

Key responsibilities & impact

Translate Propulsion Thermal Management system requirements, system functions, and Behavioral Test Specifications into traceable system test cases, procedures, and acceptance criteria.
Develop, maintain, and execute automated System Behavior Tests and functional system tests across CoSim/SIL environments, with targeted validation on HIL benches and vehicles.
Validate end-to-end thermal-management behavior, including battery heating and cooling, thermal protection, cabin conditioning, diagnostics, and degraded operating modes.
Support CoSim package readiness by checking package health, interfaces, configurations, virtual ECU behavior, plant-model connectivity, HWIO behavior, and environment sanity.
Review automated regression results and isolate product/software defects from modeling, infrastructure, configuration, or test-script issues.
Document failures, track defects through resolution, and verify corrective actions through retest and regression.
Partner with engineering, architecture, quality assurance, integration, calibration, and validation teams to define test scope and support milestone readiness.
Maintain test scripts, procedures, test data, dashboards, and documentation; share lessons learned and reusable test patterns.
Participate in product, architecture, model, and test-environment reviews, providing feedback on testability, observability, requirements, and verification strategy.
