Freelance Product Designer

Job Overview

This role focuses on the redesign of a high‑current brass battery terminal for advanced lithium battery packs in electric vehicle and energy storage applications. The primary objective is to reduce the terminal's weight while maintaining its electrical and mechanical performance. The successful candidate will leverage their expertise in connector design, 3D modeling, and FEA to deliver a robust, manufacturable solution that meets stringent industry standards.

Responsibilities

• Redesign a 300A brass battery terminal to achieve a target weight reduction from 83.75g to approximately 57g without compromising performance
• Develop optimized 3D CAD models and detailed 2D drawings, including GD&T, material, and plating specifications
• Provide DFM recommendations for forging, stamping, or CNC production processes
• Conduct electrical and thermal FEA to assess current flow, temperature rise, and short‑circuit forces
• Generate a derating curve and prototype validation plan covering thermal soak, contact‑resistance, torque, and vibration testing
• Prepare a comprehensive design report summarizing test targets, validation results, and a comparison of weight and cost versus the current design
