System Design

I was the feature/system owner for the Low Voltage system (12V Battery management, 12V power delivery, HV-LV DCDC Conversion, 12V battery state estimation, LV-HV precharge). I identified the desired customer experience for the features through cross-functional collaboration with UI/UX, electrical architecture, hardware, and other control domain teams, and delivered the features for the launch of the R1T, R1S, and Amazon Prime Delivery Van. I was also responsible for the design of the system behavior system function allocation, functional safety concept, diagnostics, and the definition of cascading software and hardware requirements.

System Verification/Validation (V&V) and Lifecycle support

In addition to the design requirements, I also drove the definition of testing requirements with traceability, authored vehicle validation test specification documents, performed hands-on validation testing, debugging, root cause analysis, and implementation of mitigation actions at the system level, touching both SW and HW of the vehicle. This was not only limited to development vehicles, but also included customer vehicles deployed in the field as well. Going further, I also provided technical input to the service team and the technical writing team to correctly identify service actions and the content of the customer user manuals.

Manufacturing

During the launch of the R1T, I supported production rate ramp up. This included designing End-of-Line routines as well as identifying some critical areas of weaknesses in the manufacturing flow and testing coverage at various stages of the assembly process.

Supplier Management

I doubled as a design release engineer for a supplier component (DCDC HV-LV power electronics converter) and delivered it in time for launch. This included all aspects including, but not limited to, SW/HW integration, component validation in vehicle, DVP&R, DFMEA, PPAP sign-off, EBoM management, and functional safety sign-off.
