# Mark Park > Engineering Leader at EarthGrid Location: San Francisco Bay Area, United States Profile: https://flows.cv/markpark ## Work Experience ### VP of Engineering @ EarthGrid PBC Jan 2025 – Present ### Engineering Manager - System Design and Research @ EarthGrid PBC Jan 2024 – Jan 2025 ### Staff System Engineer @ EarthGrid PBC Jan 2023 – Jan 2025 | Richmond, California, United States ### Staff System Engineer - Vehicle Energy Management Controls @ Rivian Jan 2022 – Jan 2023 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. ### Vehicle Energy Systems Engineer @ Rivian Jan 2020 – Jan 2022 ### Electric Vehicle Powertrain System Engineer @ General Motors Jan 2018 – Jan 2020 | Greater Detroit Area During my time at General Motors, I worked on future Battery Electric Vehicle propulsion system known as the BEV3 platform. My role was to drive the high voltage (HV) and low voltage (LV) architecture design through quantitative analysis. This included de-composing vehicle level attributes, cascading them down to propulsion system requirements on the drive unit, the HV battery pack, and the LV network architecture. Specifically, this meant performing Analysis of Alternatives (AoA) and trade-off studies to choose the most optimal design candidates, mitigating all customer facing risks at the vehicle level caused by a single point failure (System DFMEA), and working with the simulation analysis group to ensure the calculated vehicle performance matched the program requirements. ### Design Release Engineer - Fuel Systems @ FCA Fiat Chrysler Automobiles Jan 2016 – Jan 2018 | Auburn Hills, Michigan I was in the Hybrid Fuels Team at Chrysler, working on the fuel systems of the Grand Commander, a Plug-in Hybrid Electric Vehicle that launched in 2018, in China. I was responsible for the design, integration, and validation of the fuel tank, the evaporative emissions systems, and the fuel lines of this vehicle. I made sure that the system successfully passed all emissions, crash safety, performance, and overall design requirements to produce a vehicle that is safe, manufacturable, and serviceable. This included various duties such as mechanical design, Design Failure Mode and Effects Analysis (DFMEA), Engineering Bill of Materials (EBoM) and change management, supplier management, and system validation such as hot and cold ambient test trips. During my time at FCA, I've led an interesting project to improve the reliability and reduce the warranty cost of the evaporative emission system, applicable to all PHEV portfolio at FCA. This involved cross functional collaboration between the vehicle software, callibration, and the fuel systems team. ### Manufacturing Engineering Co-op @ Eclipse Scientific Jan 2015 – Jan 2015 | Waterloo, ON ### Student Designer @ The Mitchell Partnership Inc.
