RoleWe are seeking a Mechanical Design Engineer to support the design and development of structural battery hardware (e.g., enclosures, trays, lids/covers) and/or provide engineering support equipment (fixtures, test-bucks, test setups, and prototype/demo manufacturing equipment).
You'll work closely with senior engineers and cross-functional partners (analysis, test, manufacturing) to translate concepts into hardware that meets performance, reliability, and manufacturability needs.
ResponsibilitiesMechanical Design & Product Development- Support design of structural components for HV battery packs such as enclosures, trays, covers, and related brackets/interfaces under thermal, mechanical, and environmental constraints
- Create and iterate 3D CAD models and assemblies; contribute to design trades (weight, stiffness, cost, manufacturability) with guidance from senior engineers.
- Apply DFM/DFA fundamentals in part and assembly design (fasteners, sealing concepts, stack-ups, serviceability).
- Produce 2D drawings with clear notes, basic GD&T, and manufacturing intent; support tolerance studies as needed.
- Provide directional guidance through simulations to steer the design and architecture when dedicated CAE resources are limited.
- Develop comprehensive 2D drawing packages applying appropriate GD&T and conduct tolerance analyses to ensure assembly integrity and performance.
Fixtures, Bucks, and Prototype/Test Equipment- Design and develop fixtures, bucks, test setups, and prototype/demo pack manufacturing equipment to support proof-of-concept builds and validation.
- Help maintain and improve existing fixture designs (updates, repairability, usability, documentation).
- Work with standard fixturing components and vendor catalogs; select appropriate hardware and mechanisms.
Hands-On Build Support & Collaboration- Partner with manufacturing/shop resources during fabrication, prototype builds, and assembly debug-bringing a "design it, build it, improve it" mindset.
- Coordinate with suppliers for quotes, DFM feedback, and part delivery; assist with incoming inspection and fit/function checks.
- Support test activities (vibration/structural/environmental) and document findings; assist in root-cause investigations and corrective actions.
Validation & Testing- Support component and system-level validation, including vibration, structural, and environmental testing.
- Support in validation, durability, and abuse testing activities to ensure performance and reliability.
- Drive root-cause analysis and corrective actions for mechanical performance issues.
Qualifications- B.S. in Mechanical Engineering (or related), or a technical diploma in Mechanical Technology/CAD with equivalent hands-on experience.
- 3+ years of mechanical design experience (product, structures, automation equipment, fixtures, or custom machinery).
- Proficiency in 3D CAD (SolidWorks, Inventor, NX, CATIA, or similar).
- Experience producing 2D drawing packages; familiarity with GD&T concepts and tolerance stack-up basics.
- Working knowledge of fabrication/manufacturing methods (machining, sheet metal, welding, fastening, bonding) and how they influence design decisions.
- Comfortable in fast-paced, iterative development environments; strong communication and documentation habits.
Preferred Qualifications- Experience with HV battery systems and structural designs (or adjacent structural systems like automotive body/chassis).
- Familiarity with manufacturing processes such as machining, injection molding, 3D printing, and extrusions.
- Exposure to FEA/structural analysis tools (ANSYS, Abaqus, LS-DYNA, etc.) at a basic level (interpretation/collaboration vs. ownership).
- Knowledge of design release workflows for mechanical parts and assemblies.
- Comfort working with electro-mechanical designs.
Why Join?- Innovative Technology: Work on cutting-edge energy storage solutions that power the future.
- Career Growth: Opportunities to work on high-impact projects and advance in a growing industry.
- Competitive Benefits: Comprehensive health, wellness, and professional development programs.
- Mission-Driven Culture: Be part of a team that is shaping the future of sustainable energy through innovation and excellence.
