1. Battery Pack Design & Packaging

Design and develop battery pack components including enclosures, structural parts, cooling systems, busbars, brackets, and mounting systems.

Create 3D CAD models, assemblies, 2D drawings, and BOMs.

Support battery pack packaging studies considering vehicle integration, serviceability, manufacturability, and safety requirements.

Define and manage component interfaces and packaging constraints.

2. Mechanical Design & Product Development

Develop detailed designs from concept through production release.

Apply GD&T principles and engineering standards in component design.

Support DFMEA, DVP&R, design reviews, and engineering change management activities.

Collaborate with suppliers and internal teams for component development and issue resolution.

Ensure compliance with DFM/DFA guidelines and automotive quality standards.

3. CAE & Validation Support

Work with CAE teams to support structural, thermal, vibration, and crash simulations.

Review simulation results and implement design improvements.

Support DV/PV testing, environmental testing, vibration testing, and performance validation.

Participate in root cause analysis and corrective action implementation.

4. Cross-Functional Collaboration

Coordinate with battery, thermal, electrical, BMS, manufacturing, and vehicle integration teams.

Support technical discussions with suppliers and program stakeholders.

Track engineering deliverables, open issues, and design changes throughout the development cycle.

Ensure timely release of engineering documentation and design updates.

5. Manufacturing & Launch Support

Support prototype build activities and production trials.

Collaborate with manufacturing teams on tooling, assembly processes, and design optimization.

Participate in PFMEA reviews and process validation activities.

Support launch readiness and production issue resolution.
