EVRaid is looking for Battery Pack Design & Prototype Engineer To Design, build, and validate production-ready lithium battery packs, working on the full cycle from sizing and CAD design to prototype build, supplier coordination, and manufacturing handover. The role bridges mechanical design, electrical integration, and production execution.
Key Responsibilities
- 1. Battery Pack Design & Engineering
- · Design lithium battery packs from concept to production-ready designs.
- · Perform battery pack sizing (voltage, capacity, configuration) based on application requirements.
- · Develop full 3D CAD models using SolidWorks, including enclosures and internal layouts.
- · Ensure proper electro-mechanical integration between cells, BMS, wiring, thermal paths, and mechanical structures.
- · Select cells, BMS, connectors, busbars, fasteners, and auxiliary components.
- 2. Prototyping & Build
- · Build battery pack prototypes hands-on, including mechanical assembly and integration.
- · Support prototype iterations based on design reviews, testing feedback, or manufacturing constraints.
- · Prepare and refine designs to be scalable beyond prototypes.
- 3. Manufacturing & Supplier Interface
- · Prepare manufacturing and assembly drawings for production.
- · Create and maintain detailed BOMs, including supplier sourcing and alternatives.
- · Develop costed BOMs and support cost optimization efforts.
- · Coordinate with suppliers and factories on manufacturability, tolerances, and lead times.
- 4. Cross-Functional Collaboration
- · Work closely with: BMS Engineers , Production and operations teams, Sales and business development teams,External suppliers and manufacturing partners.
- · Translate customer or sales requirements into feasible technical designs.
- 5. Validation & Testing
- · Support validation and testing activities for battery packs.
- · Review test results and implement design improvements.
- · Ensure designs meet functional, mechanical, and integration requirements prior to production release.
Must Have
- Strong background in mechanical or electro-mechanical engineering
- Proven experience designing battery packs or similar electro-mechanical systems
- SolidWorks
- Hands-on prototyping and build experience
- Strong understanding of electrical–mechanical integration
- Ability to work across engineering, production, and commercial teams
Nice to have
- Experience with lithium battery systems (LFP, NMC, etc.)
- Exposure to manufacturing environments and supplier coordination
- Costing and DFM (Design for Manufacturing) experience
