Job description

There was a time when all of America believed that the future of the physical world could be radically different. The engineers of the mid-1900s put a man on the moon in eight years, designed and built planes and submarines from scratch in under three, and conceived of building things we wouldn’t even be able to dream up today. Today, the last of the engineers who imagined and built these systems are retiring. As they go, we lose not only the engineering knowledge gained from their decades of imagination and trial-and-error, but also the spirit that made that imagination possible. Amca is working day-in and day-out to restore America’s ability to engineer anything that our critical systems depend on, and reinvigorate the cycle of creation that allows imagination to shape physical reality. We rapidly develop and manufacture new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. By restoring the capability of our antiquated supply chains, we increase the country’s capacity to imagine and realize new systems, and make a physical world that looks very different from today. Overview: The Mechanical Build Engineering role is responsible for owning the build procedures used to develop qualification hardware, and iterate on the initial builds to ensure highly reliable production level builds at our factories once product maturity has been achieved. You will serve as the extreme owner for build process of the parts we design.
