CNC Manufacturing Engineer - Build the Future of Advanced Manufacturing

Hawthorne, California | On-site

A venture-backed advanced manufacturing startup is developing next-generation production technologies that enable faster, higher-quality fabrication of complex engineered components. The team is focused on solving longstanding manufacturing challenges through innovative processes that improve performance, scalability, and production efficiency across aerospace, defense, energy, and industrial applications. As a CNC Manufacturing Engineer, you will play a hands‑on role in machining high‑precision tooling, molds, fixtures, and prototype components that support both product development and production efforts.

This position offers the opportunity to own machining operations from programming through finished part delivery while working closely with engineers to improve manufacturability and production readiness. The role is ideal for someone who enjoys operating at the intersection of design, manufacturing, and shop‑floor execution.

We are an early‑stage manufacturing technology company focused on transforming how advanced engineered products are designed and built. Our team combines expertise in engineering, automation, and production systems to develop scalable manufacturing solutions for demanding industries. We move quickly, value ownership, and prioritize practical execution that delivers measurable results.
