Mechanical Engineer (L1-L2)

The Opportunity 

We are looking for a motivated Mechanical Engineer who thrives on rapid iteration. We move with the speed and autonomy of a startup to bring next-generation battery technologies to market. In this role, you will work cross-functionally with our in-house teams to develop the next generation of battery and powertrain technologies for high-performance mobility and consumer applications.

You will take on project ownership and design high-quality mechanical systems across a diverse product portfolio. Your impact will span the entire development lifecycle—from initial CAD design and simulation to rigorous validation testing, prototyping, and manufacturing bring-up. The ideal candidate values precision, thrives on technical challenges, and possesses excellent communication skills to bridge the gap between complex engineering and cross-functional execution.

 

What You'll Do

• Design and model mechanical components and assemblies using SolidWorks CAD and PDM.
• Execute structural, thermal, and fluid simulations, correlating digital results to physical testing.
• Develop and execute test plans and design validation methods for battery system failure modes.
• Perform trade-off analyses and DOEs to optimize designs for performance and cost.
• Lead prototype builds and support manufacturing bring-up for new product lines.
• Collaborate with interdisciplinary teams (Electrical, Software, Systems) to deliver high-confidence products.

Qualifications You'll Bring

• 2+ years of mechanical engineering experience, ideally involving battery technologies.
• Hands-on experience with rapid-prototyping to create functional jigs and fixtures.
• Experience designing for CNC Machining, Injection Molding, Sheet Metal, and 3D Printing.
• Familiarity with laser welding and IP67 sealing methods.
• Ability to clearly communicate technical issues in succinct language to non-technical teammates.
• BS, MS, or MEng in Mechanical Engineering.

What Makes You Stand Out

• Experience designing for consumer products, e-mobility, automotive, or aerospace applications.
• Experience with manufacturing bring-up, both in-house and with external contract manufacturers (CMs).
• Familiarity with PDM and PLM systems for revision control.
• Knowledge of safety and transport standards (UN 38.3, UL 2580, UL 2271).
• A demonstrated ownership mindset and the ability to thrive in ambiguity and fast-paced environments.
