You will be responsible for the definition, validation, and continuous improvement of all electrical test stations, from high-voltage safety tests to functional verification, ECU/BMS flashing, and diagnostics, ensuring that every product leaving the line is safe, functional, and fully traceable. Experience in battery or EV manufacturing is strongly preferred., * Own the EE-Check and EOLT processes end to end: test strategy, test coverage definition, station specifications, and process documentation. * Define and maintain electrical safety test procedures for HV battery packs: hipot/dielectric strength, insulation resistance, continuity, and HV interlock verification. * Develop, implement, and optimize functional test sequences hands-on: BMS communication and diagnostics (CAN/UDS), sensor verification, charge/discharge validation, capacity and internal resistance checks - including test software/sequence changes under version control. * Manage ECU/BMS flashing and parameterization processes at end of line, including software/parameter version control and traceability. * Specify, qualify, and commission EOL test equipment and test benches with suppliers: URS/FDS definition, FAT/SAT, correlation studies, and Gauge R&R / measurement system analysis. * Perform process validation and qualification for new test stations and product variants - IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification. * Define pass/fail criteria and test limits in collaboration with R&D, Quality, and Homologation; manage limit changes under engineering change control. * Analyze test data and first-pass yield: identify failure Pareto, drive root cause analysis (8D) on recurring EOL failures, and reduce false rejects. * Ensure full traceability integration of test results into MES and data systems (test records, serial number binding, batch genealogy). * Support production on escalated EOLT issues: complex diagnostics, retest strategies, and disposition of failed units. * Standardize test processes across lines and product generations; document work instructions and train technicians and engineers. * Drive continuous improvement: cycle time reduction, test coverage vs. takt trade-offs, predictive analysis of test data ## Related Videos - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [A Hitchhikers Guide to Container Security - Automotive Edition 2024](https://www.wearedevelopers.com/videos/1119-a-hitchhikers-guide-to-container-security-automotive-edition-2024) - [Testing .NET applications a Tool box for every developer](https://www.wearedevelopers.com/videos/704-testing-net-applications-a-tool-box-for-every-developer) - [Developer Tools for Microsoft Azure](https://www.wearedevelopers.com/videos/450-developer-tools-for-microsoft-azure) - [The 2025 State of JavaScript Testing](https://www.wearedevelopers.com/videos/1678-the-2025-state-of-javascript-testing) - [Build UIs that learn - Discover the powerful combination of UI and AI](https://www.wearedevelopers.com/videos/124-build-uis-that-learn-discover-the-powerful-combination-of-ui-and-ai) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs) - [What’s the Difference between a Junior, Mid, and Senior Developer?](https://www.wearedevelopers.com/magazine/238-what-s-the-difference-between-a-junior-mid-and-senior-developer)
