About The Position

You will be the driving force behind the full mechanical development lifecycle of our battery module products. That means owning designs from initial concept and first-article prototypes, through development testing, design validation, and into high-volume manufacturing. You will work closely with electrical, manufacturing, and systems engineering counterparts to deliver robust, producible hardware on aggressive schedules. This is a hands-on role. You will be building and testing prototypes yourself, running experiments, and iterating quickly. If you are the type of engineer who is equally comfortable at a CAD workstation and a build bench, this role is for you.

Requirements

• B.S. or M.S. in Mechanical Engineering
• 5+ years of experience in product development with demonstrated ownership of hardware from prototype to production
• Strong fundamentals in heat transfer, fluid mechanics, solid mechanics, and mechatronics
• Expert-level Solidworks proficiency, including drawings with full GD&T
• Hands-on experience with FEA tools (ANSYS, Abaqus, Solidworks Simulation, or similar) and CFD tools (Fluent, Star-CCM+, or similar)
• Ability to improvise and test solutions quickly, you prototype on your own, not just through vendors
• Experience designing for high-volume manufacture: injection molding, sheet metal, castings, extrusions, weldments
• Comfortable working in a small team where ambiguity is normal and self-direction is required

Nice To Haves

• Experience with battery systems, power electronics enclosures, or thermal management for high-energy-density products
• Background in marine, defense, automotive, or industrial equipment markets
• Familiarity with IP-rated enclosure design and sealing strategies
• Experience with liquid cooling systems design and qualification

Responsibilities

• Mechanical design of battery module enclosures, thermal management systems, and structural assemblies from concept through production release
• Prototype fabrication and first-article builds, you will get hands-on, not just hand off drawings
• Development testing: design validation, environmental, vibration, thermal, and ingress protection testing
• DFM/DFA collaboration with manufacturing engineering to ensure designs are producible and scalable
• FEA and CFD analysis to validate designs analytically before committing to hardware
• Managing and releasing engineering drawings, GD&T callouts, and BOMs in Solidworks PDM
• Pathfinding new designs and materials, identifying better solutions before problems surface in production
