Responsibilities

Industrialization: Lead the transition of components from design through high-volume manufacturing, ensuring robust and scalable production processes including end-of-line diagnostics, VIN programming, and commissioning routines.
Lead Integration: Own the design and functional validation of the low-voltage battery and keyfob, driving integration and testing across bench, labcar, and vehicle environments.
Cross-Functional Development: Develop components in collaboration with cross-functional teams—including Controls, Security, Software, Purchasing and Manufacturing—to achieve objectives within budget and program timelines.
Subject Matter Expertise: Serve as the single point of contact for electrical integration issues across assigned components, providing rapid response and expertise to resolve critical concerns impacting vehicle development.
Software Collaboration: Partner with software and supplier teams to develop, integrate, and validate application software, bootloaders, diagnostics content, and OTA-compatible update workflows for assigned components.
Launch Support: Support vehicle assembly lines during development phases, validate system-level changes, and drive issue resolution to ensure on-time delivery and smooth production ramp-up.
Quality Control: Develop and implement quality control measures, DVP&R strategies, and testing protocols for assigned components.
Testing & Debugging: Perform vehicle-level testing and debugging, including data analysis and organizing cross-functional reviews across low-voltage battery and wireless vehicle access domains.
Requirements Allocation: Perform detailed trade studies, requirements allocation, and interface definition studies to translate requirements into hardware, software, electrical, RF, and network specifications with a focus on industrialization and manufacturability.
Reporting: Report feature development progress and maturity at key program milestones.
