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, with our people 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.
This position is for a Model Based Systems Engineer in Boulder, CO. You will work closely with a talented team to assist in the design, implementation, and maintenance of critical defense systems through classic and modern Systems Engineering techniques. You will be tasked with improving the overall project management discipline of our clients by increasing collaboration and innovation, introducing techniques that promote adaptability and flexibility in the face of unpredictable circumstances, and optimizing return on investment expenditures.
You will operate at the intersection of requirements development, systems design, and integration testing in a fast-paced defense environment. This role requires deep experience in Model-Based System Engineering (MBSE) to support mission design work, process definition, and baseline management. Experience with Overhead Persistent Infrared (OPIR) missions is a significant bonus.
To be considered for this role, you must be a US Citizen with an active US government security clearance. Additionally, you must either live near or be willing to move to the Boulder, CO area. This role is onsite in Boulder, CO.
