About the Company

We are a stealth-mode battery startup developing cutting-edge battery technology. Our mission is to revolutionize battery technology to accelerate the global transition to clean energy. By leveraging innovative materials and advanced manufacturing techniques, we are building the future of sustainable energy.

Can’t find the company name?

It’s not you, it’s us! We’re really excited about the potential of our technology, product, and mission, and have chosen to remain in stealth mode.

Role

We 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.

Responsibilities Mechanical 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 (Solid Works, 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.
