About Centil

Centil, a Sabel Systems company, is a mission-focused engineering team supporting some of the highest-priority space defense programs in the U.S. Space Force portfolio, including missile defense and missile warning systems for Space Systems Command. Our work spans DevSecOps, CI/CD product development, and space-domain systems engineering, and our people are embedded directly in the programs they support.

In January 2026, Sabel Systems acquired Centil to expand its Advanced Engineering Services capabilities. For our team, that means access to a broader portfolio of programs, deeper corporate resources, and new career pathways - while preserving the technical ownership and small-team culture that defines how we work. It's an exciting time to join Centil: we're growing, the mission portfolio is expanding, and we're building the team that will define what comes next.
