Tesla, Gigafactory Nevada – Mechanical Engineering Technician – NPI (Optimus, Powerwall) Sep 2024 – Present

• Led NPI initiatives for Optimus Robot and Powerwall lines, managing large-scale project timelines, FAT (Factory Acceptance Testing), and MBOM creation. Conducted DFMEA/PFMEA, process capability analysis (Cp/Cpk), and equipment validation to support production ramp-up.

• Owner of IP66, Zone-4 sheet-metal/plastic housing: cut mass 11 % via static + modal FEA while meeting 4 g vibe.

• Deployed automated potting-dispense, vision screw-drive, and leak-test cells—line at rate in T-0 + 14 days.

• Authored PFMEA and CATIA drawing packages enabling zero ECOs during pilot build.

• Drove enclosure BOM cost 9 % via extrusion profile consolidation and supplier VA/VE workshops. SharkNinja, Needham, MA – Mechanical Engineer – Co-op (NPD, R&D) Feb 2024 – Aug 2024 / Jun 2023 – Aug 2023

• Developed cost-effective peristaltic pump system, reducing unit cost by 80% via DOE (Minitab), material selection, and design iteration.

• Led design, prototyping, and testing of wet brushroll assemblies achieving 98% debris evacuation efficiency. Utilized SolidWorks, CREO, and 3D printing for rapid prototyping and DFM optimization of electromechanical subsystems.

• Conducted fluid testing, circuit soldering, and thermal analysis; documented design intent through DFMEA, GD&T, and DVP&R. Created drying tray systems with 90% moisture reduction, enhancing drying time and user experience. Valcon Valves Manufacturing Pvt Ltd, India – Junior Manufacturing Engineer Jul 2021 – Jun 2022

• Achieved 25% cost savings and 7.5% weight reduction in valve design through Lean manufacturing and CAD redesign. Managed die casting and lost wax casting operations from design stage to final inspection and FAT approval.

• Performed cryogenic testing at –196 C,FEA simulations(ANSYS) to identify failure modes under high internal pressure.

• Led fixture development and process troubleshooting across extrusion, milling, welding, and rubber molding operations. Collaborated with QA team to ensure dimensional accuracy, surface finish, and functional performance during pre-dispatch inspection.
