Full Job Description

Build the Future of Energy at Lithionics

At Lithionics, we’re redefining what’s possible in lithium-based energy storage. Our cutting-edge battery systems power mission-critical applications across marine, RV, specialty vehicle, and industrial markets. If you’re passionate about turning bold ideas into manufacturable, high-performance products, we want you on our team.

We’re seeking a Mechanical Engineer II who thrives at the intersection of innovation, precision, and production. In this role, you’ll help bring advanced battery systems from concept to reality—designing, validating, and optimizing solutions that are safe, scalable, and built to last. We are looking for someone with experience in designing multiple-component products that go to an end user.

What You’ll Do

As a Mechanical Engineer II, you’ll play a hands-on, high-impact role throughout the product lifecycle:

Design & Engineering

Lead the mechanical design of battery modules and enclosures with a focus on thermal management, structural integrity, and safety
Translate early concepts into robust, production-ready designs

Electromechanical Integration

Partner closely with Electrical Engineering to design busbars, wire harnesses, and PCB mounting solutions
Ensure proper creepage and clearance for high-voltage applications

Documentation & Standards

Create detailed blueprint drawings and technical specifications
Perform QA/QC reviews of peer designs to ensure accuracy and manufacturability
Apply GD&T (ASME Y14.5) to ensure proper fit and function

Analysis, Validation & Testing

Lead DFMEA sessions to proactively identify and mitigate risk
Develop and execute DVP&R plans
Oversee physical testing for vibration, thermal performance, ingress protection, and crash requirements

Manufacturing & Production Support

Develop comprehensive assembly documentation
Provide hands-on support on the manufacturing floor
Troubleshoot production challenges using 8D root-cause analysis

Leadership & Ownership

Serve as a technical mentor to junior engineers and designers
Help train team members on CAD best practices and SOPs
Act as Project Engineer for assigned product lines, coordinating with vendors and cross-functional teams (Electrical, Thermal, Software)

What You Bring

Required Qualifications

Bachelor’s degree in Mechanical Engineering or a related technical field
3+ years of professional mechanical design experience (must have actual design, not process, experience)
(Battery systems, automotive, power conversion, or aerospace experience strongly preferred)
Expert-level proficiency in SolidWorks or Autodesk Inventor
(CSWA/CSWP or equivalent certification a plus)
Strong understanding of:
- Material selection (plastics, sheet metal, busbars)
- Thermal interface materials
- DFM/DFA best practices

Preferred Experience

Experience with lithium-based battery systems
Background in Formula SAE, Solar Car, or similar hands-on engineering competitions
A mindset that views challenges as opportunities to innovate and improve

Why Lithionics?

Innovative products that make a real-world impact
End-to-end engineering exposure—from concept through production
A collaborative, technically driven culture
Opportunity to grow into technical leadership roles
Competitive compensation and benefits

Ready to Power What’s Next?

If you’re excited to design products that push the boundaries of energy storage and want to work with a passionate, high-performing engineering team, we’d love to hear from you.

Apply today and help engineer the future with Lithionics.
