CNC Manufacturing Engineer - Advanced Aerospace Manufacturing

Hawthorne, California | On-site

Join an early-stage aerospace and defense manufacturing company developing a new approach to producing high-performance composite components. The technology enables complex, lightweight hardware to be manufactured faster and at greater scale, with applications across aerospace, defense, and other demanding industries. As a CNC Manufacturing Engineer, you will work directly with engineering and production to manufacture precision molds, tooling, prototypes, and components.

You will own machining work from CAM programming and setup through finished hardware while gaining exposure to broader manufacturing engineering responsibilities. This is a strong opportunity for an early-career engineer who enjoys working with both CAD and physical hardware and wants to grow quickly in a hands-on startup environment.

We are a venture-backed advanced manufacturing startup developing new methods for producing lightweight composite hardware. Our team works across engineering, machining, tooling, composites, and production to move complex parts from design into physical hardware quickly. Engineers work directly with the manufacturing process and have opportunities to take on increasing technical and operational responsibility as the company grows.
