Sierra Space manufactures satellite platforms, subsystems, and reusable spaceplanes for U.S. defense and civil missions. The tech stack reveals dual operational tracks: traditional aerospace engineering (MATLAB, STK, LIDAR, GPS) alongside modern DevOps infrastructure (Kubernetes, GitHub Enterprise, CI/CD pipelines, cloud platforms). Engineering dominates the hiring mix, and active projects cluster around spacecraft simulation, GNC systems, and the Dream Chaser vehicle—suggesting capital-intensive hardware development paired with software modernization for mission ops.
