Testing Engineer

Job description

Test and Validation Engineering (Power Converters – up to MW range)Role SummaryThis role owns the V&Vof high-power converter systems—from early validation strategy to final regulatory approvals across global markets (India, EU, US). Testing Engineer will Support forEnsuringKey Responsibilities1. Test Strategy & Validation ArchitectureDefine end-to-end V&V strategy aligned with certification requirementsDevelop Design Verification Plan (DVP) & Product Validation Plan (PVP)Ensure traceability from requirements → test cases → certification clauses2.

Support Test Infrastructure DevelopmentBuild and manage:MW-scale test benchesGrid simulators & regenerative load setupsBattery emulators for PCS validationEnsure infrastructure supports pre-compliance + certification testing3.

Test Automation & HILLead automation architecture

Python / LabVIEW / TestStand frameworksDevelop HIL-based certification scenarios: Grid fault simulationsDynamic grid behavior4.
