The threat surface isn't just digital here - it's orbital, hypersonic, and kinetic. Sierra Space operates at the intersection of defense tech and space infrastructure, building satellite platforms, reusable spaceplanes, and propulsion systems for U.S. national security missions and allied customers. The company's Dream Chaser spaceplane is the only winged commercial vehicle of its kind, and its LIFE habitat is an inflatable structure designed for commercial space stations. Three decades of heritage mean the systems already fly; the security challenge is keeping them - and the data they carry - locked down.
Cybersecurity at this scale means defending the full stack: spacecraft command-and-control, ground segment networks, supply chain integrity across critical subsystems, and the software pipelines feeding hypersonic and propulsion development. The attack surface spans IT, OT, and flight systems simultaneously. Expect work across classified and unclassified enclaves, hardening infrastructure that supports missions where failure has consequences measured in national security, not uptime.
Based in Colorado, Sierra Space serves U.S. national security customers, civil agencies, and global allies. The engineering domains - satellite platforms, hypersonics, reusable spaceplanes, propulsion - each carry distinct threat models, from adversarial nation-state actors targeting telemetry to supply-chain compromise in dual-use components. If you're looking to secure systems where the red team isn't just hypothetical, the operational context here is concrete.
