About The Position

Astro Mechanica is a vertically integrated aerospace company developing a scalable technology platform to power critical infrastructure, mission operations, and the future of flight. We apply aerospace engineering and quality standards across our products, delivering high performance, reliability, and efficiency for the most demanding operating environments. Astro Mechanica is backed by leading venture and strategic investors, including Andreessen Horowitz (a16z), Giant Step Capital, United Airlines Ventures, and Voyager Ventures. We’re a team of passionate engineers dedicated to advancing aerospace. We’re generalists with specialist depth, united by a flat structure and a shared obsession with building things that work well. We move fast, stay pragmatic, and let engineering excellence speak louder than hierarchy. You’re a seasoned People leader who combines strategic perspective, business acumen, and operational rigor. You’ve built in early-stage environments and led at scale, and know how to translate business priorities into effective teams, programs, and systems. You know what great looks like—and how to build toward it through practical, iterative steps. You earn trust through sound judgment, clear communication, and reliable follow-through. You’re as comfortable managing a benefits renewal, resolving an employee issue, or fixing a workflow as you are advising leaders and designing programs.
