Mechanical engineer jobs in California

About the role

We are hiring a Senior Mechanical Engineer to lead the structural, packaging, and thermal design of our high-power battery energy storage systems, power conversion systems, and ground support equipment. You will own mechanical problems end to end, from blank-paper concept through fabrication, validation, and field deployment. This is a hands-on, on-site role. You will work alongside electrical engineers, field ops, and fabricators. You will not hand work off. You stay with the problem until it is solved.

What you'll bring

• Proven ability to take a design from blank paper through fabricated assembly independently
• Hands-on experience with measurement, assembly, and fabrication of hardware while managing requirements and outline design criteria
• Knowledge of appropriate material selection
• Comfortable functioning as the sole mechanical engineer on a project, setting priorities and managing your own work without a mechanical engineering group to lean on
• 3 or more years with multiple 3D CAD systems
• ability to work in SolidWorks and learn OnShape (no OnShape experience required, no certifications required)
• Able to ask questions, seek solutions, and operate effectively in a fast-paced R&D and build environment
