About The Position

Mach Industries is seeking a Build Engineer to own the transformation of our products from new designs to reality. In this role, you will work closely with the Product Engineering and Manufacturing teams to build first articles, enable rapid design iteration, and capture critical lessons that shape how products mature into production. This is a hands-on role that demands resourcefulness, speed, and technical rigor. At Mach Industries, we are building decentralized, autonomous systems to maintain an allied American edge in modern warfare. As a Build Engineer, you will play a pivotal role in proving out design concepts through the initial manufacturing phase. Working with a world-class engineering team, you will bridge the gap between design and manufacturing, delivering solutions that ensure manufacturability, cost-efficiency, and mission-critical reliability.
