The Battery Pack Mechanical Hardware Development Engineer II will join the Drone Electric Propulsion Subsystem team, focusing on solving complex hardware engineering challenges related to battery systems. This role involves designing, developing, and validating high-voltage battery packs from concept to production. The engineer will need to demonstrate strong technical depth in battery pack design and system-level thinking. Collaboration with cross-functional teams is essential to ensure the successful integration of mechanical and electrical components.

• Bachelor's degree in mechanical engineering or equivalent
• 4+ years of working in mechanical engineering or equivalent experience
• Demonstrated experience taking a mechanical design from concept through prototype to production
• Battery pack mechanical design experience including cell-to-pack architecture and module design
• Proficiency in CAD software such as SolidWorks, Creo, CATIA, or NX
• Understanding of high-voltage safety practices and requirements
• Familiarity with thermal runaway mitigation techniques
• Experience with design for manufacturing and assembly (DFM/DFA)
• Knowledge of tolerance analysis and working with suppliers on tooling
• Experience with prototyping and validation testing

• Design mechanical architecture for high-voltage Li-Ion battery packs
• Create detailed 3D models and manufacturing drawings using CATIA with GD&T
• Develop packaging concepts balancing energy density, safety, and manufacturability
• Perform FEA and tolerance stack-up analysis to validate designs
• Plan and execute prototype builds and validation testing
• Design to high-voltage safety requirements and ensure compliance with applicable standards
• Develop verification test plans to verify designs against relevant standards
• Collaborate with electrical, BMS, systems, and safety engineers
• Maintain engineering documentation and manage changes through PLM
• Identify opportunities for continuous improvement in cost, weight, safety, and manufacturability
