Lead Mechanical Automation Engineer

Lead Mechanical Automation Engineer - Join a Fast-Growing Startup Advancing Next-Generation Manufacturing!

El Segundo, CA | On-site

A rapidly scaling hardware startup is developing breakthrough manufacturing systems that enable high-performance composite structures to be produced at significantly faster speeds and lower cost. The team is expanding its automation capabilities to support high-volume production for critical applications across aerospace, defense, and energy. As the Lead Mechanical Automation Engineer, you will design and develop the mechanical systems that drive automated manufacturing.

You will translate complex manual steps into scalable mechanical mechanisms, own CAD design and build packages, and work hands-on to prototype and validate new equipment. This position is ideal for someone who enjoys creating mechanisms from scratch, thrives in an iterative hardware environment, and wants to build advanced automation systems.

We are an emerging technology company focused on reinventing how advanced composite components are manufactured. Our proprietary process supports rapid production of intricate structures while maintaining high performance and consistency. The team operates in a fast-paced environment where mechanical design, automation, and manufacturing intersect daily, and where engineers have a direct impact on production technology used across multiple programs.
