About the Role

This is a mechanical design engineering role focused on battery pack and module development, supporting a client in the advanced energy space. This position is centered on owning mechanical components and sub-systems from concept through production, driving design decisions, and collaborating across multidisciplinary teams.

This role operates in a fast-paced, highly collaborative environment and requires hands-on design, prototyping, and cross-functional coordination with engineering, suppliers, manufacturing, and quality teams.

• Own mechanical design of one or more battery pack components or sub-systems from concept through product launch
• Collaborate with systems, electrical, and analysis teams to ensure design requirements are met
• Identify design risks and develop prototypes to validate and mitigate issues
• Engage with suppliers to define specifications, obtain quotes, and support component development
• Create 3D CAD models and 2D drawings with GD&T for complex assemblies
• Support hands‑on prototype builds and work closely with manufacturing teams
• Perform tolerance stack analyses to ensure proper fit and functionality
• Ensure proper electrical isolation and environmental durability (thermal, vibration, sealing, etc.)
• Optimize designs using analytical, numerical, and empirical methods
• Contribute to technical problem solving and continuous product improvement

• Bachelor’s or Master’s degree in Mechanical Engineering or related field
• 2+ years of mechanical design experience (5+ years for Senior level)
• Experience designing components such as castings, stampings, extrusions, plastics, sealing systems, bus bars, or cooling systems
• Strong 3D CAD experience (Onshape or similar CAD tools)
• Experience working with suppliers and design for manufacturability (DFM)
• Familiarity with low- to mid-volume manufacturing processes
• Ability to interpret structural and thermal analysis results
• Strong problem-solving and communication skills in a cross-functional environment
• Nice to have: hands‑on prototype or product launch experience, battery or energy system background, and experience designing for harsh environments (vibration, corrosion, water ingress, thermal)
