At Aeon, we develop advanced missile systems, built for ground and air platforms. We take pride in our dynamic team that allows us to iterate, build and test quickly. If you are looking to solve hard problems with a passionate team in a hands-on, fast-paced environment, Aeon is the place for you. We are a vertically integrated defense manufacturer developing and producing advanced strike systems and critical subsystems at industrial scale for major defense programs. From its 140,000-square-foot manufacturing facility, Aeon will bring weapon design and production under one roof, including propulsion, fuzing, autonomy and other critical subsystems. Led by former special operators, senior government officials and experienced aerospace and defense engineers, Aeon is a trusted partner to U.S. government customers and industry. As a Senior Mechanical Engineer - Actuation, you'll own electromechanical subsystems on our tactical missile platform. The near-term work is maturing an existing design: carrying it through qualification, finalizing it for the production environment, and closing out the problems that only surface once you're building at rate. Once that design is locked, you'll lead clean sheet actuation and motion control work on future programs. This is a small team, so the scope is wide. You'll size the hardware, build the test stands, run the tests, write the reports, and then advocate for the design changes you think it needs. This is a full-time, in-person role in Austin, TX with plans to move to Cedar Park, TX early 2027.
