Mechanical Engineer - Clean Tech

My client has revolutionized the energy storage sector with their zero-emission technology, eliminating the need for fossil fuels in industrial applications by storing energy as heat.

They’re backed by leading climate-tech investors and are entering their next phase of growth.

We’re seeking a Mechanical Engineer who thrives in ambiguous, clean-sheet design environments
. This role will lead prototype development and scale-up efforts for their novel energy storage system.

• Drive clean-sheet mechanical design of new energy storage components and subsystems
• Work from first principles to define architecture, requirements, and form factor
• Apply DFM principles for components including sheet metal and welded assemblies
• Perform structural or thermal analysis as needed to validate concepts in high-pressure or extreme conditions
• Innovate in materials and mechanisms to create first-of-its-kind hardware
• Own the prototyping process — taking ideas from concept to physical reality

• Minimum of 8 years in mechanical engineering roles involving from-scratch product development
• Background in energy storage, aerospace, space, hardware startups, or similar industries where ambiguity and rapid iteration are the norm
• Hands‑on, resourceful, and comfortable building and testing early‑stage prototypes
