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 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.
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
(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.
