Aerospace Data Science Jobs in Texas (NOW HIRING)

Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for critical space missions, Firefly is the first commercial company to launch a satellite to orbit with 24-hour notice and the first company to achieve a successful Moon landing. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join our team and help fuel our successful trajectory into space.

As a GNC Engineer at Firefly, you will design, analyze, and operate the GNC systems of operational launch vehicles. In this role, you will develop GNC and simulation software, perform dynamic analyses, and support mission operations while continuing to build breadth across core GNC competencies. This position offers hands‑on experience with launch vehicle ascent guidance, attitude control systems, and real‑time flight operations in a fast‑paced environment. You will deepen your technical capabilities and refine your desired career trajectory, taking ownership of system elements and software tools as you grow toward a senior GNC role at Firefly.
