Work Experience
Two deployments — R&D battery systems and automotive quality.
Junior R&D Mechanical Engineer
● Oct 2025 — Present
Coulomb Li Tech Pvt. Ltd. — Battery Technology Company
- Designed the Power Distribution Unit (PDU) for HV battery packs, working closely with electrical and embedded teams to align on HV wiring architecture, circuit protection, and AIS 156 safety compliance.
- Owned the mechanical design interface in a multidisciplinary program, translating thermal and electrical requirements from partner teams into manufacturable coldplate and enclosure geometry.
- Optimized coolant flow rate and inlet temperature for a liquid-cooled battery coldplate in ANSYS Fluent, improving cooling efficiency and thermal uniformity for lithium-ion BTMS.
- Ran static thermal simulations of battery coldplates to evaluate temperature distribution, identify hotspots, and assess thermal performance under operating conditions.
- Performed static structural FEA of battery enclosures in ANSYS, verifying safety factor compliance and structural integrity under mechanical loading.
- Led sheet metal fabrication of battery system components, supporting physical prototyping, assembly, and design validation — coordinating with the shop floor to keep prototypes aligned with CAD intent.
- Designed and optimized mechanical components for battery pack assemblies in SolidWorks, contributing to overall system performance and manufacturability.
Quality Intern
Aug 2023 — Sep 2023
PCA Automobiles
- Performed detailed quality inspections on automotive components and prepared defect analysis reports to identify recurring issues and enable targeted corrective actions.
- Applied Six Sigma and Toyota Production System (TPS) methodologies to real manufacturing scenarios, building practical skills in defect reduction and process standardization.
- Drove process improvement initiatives that delivered a ~20% improvement in quality team efficiency.
- Collaborated with cross-functional teams to implement Corrective and Preventive Actions (CAPA), supporting Lean Manufacturing and continuous improvement on the shop floor.
