Looking for full time mechanical engineering opportunity 

Battery Engineering Co-op, Proterra May 2022 - May 2023 

➢ Validated end-of-line tests (Greenlight Innovation’s Emerald battery testing software) and updating battery pack build work instructions in Proterra’s MES 

➢ Reviewed Equipment drawings/BOMs using 3DX Catia and communicated with vendors to obtain quotes for over $65000 in critical spare/wear parts, resulting in a 35% reduction in downtime. 

➢ Conducted research on the rework process of battery packs to minimize scrap costs by 16% and drive continuous improvement in Test Engineering. 

➢ Utilized Critical Thinking to identify and address fixture flaws by performing tolerance analysis. Worked on redesigning/testing new fixtures and fixture-related parts using a 3D printer, resulting in a 25% increase in fixture reliability. 

➢ Processed and analyzed test data using statistical methods in Excel to validate system performance, leading to a 15% reduction in defects. 

 Successfully managed and resolved two major quality investigations to determine appropriate long-term corrective actions. Revamped Proterra’s PFMEA and control plan documents, showcasing your Test Planning and Triage skills. 

➢ Initiated two mechanical design changes related to environmental sealing and torque specifications to enhance battery packs' reliability, safety, and quality. 

➢ Created a new battery cycling test to evaluate the performance of remanufactured battery packs and standard remanufacturing work instructions for the battery service team. 

➢ Developed detailed testing plans and instrumentation maps, highlighting sensor and data acquisition needs, resulting in a 10% improvement in testing accuracy statistics
