About The Position

Concept Solutions is seeking an experienced Program Manager to lead a high-visibility federal mission application modernization program supporting a Department of War customer. This role will lead an initiative designed to transform how users access and interact with a portfolio of legacy applications—creating a unified experience with one sign-on, one work surface, and a repeatable approach for bringing applications onto a shared modern platform while ensuring existing mission-critical applications remain fully operational. The Program Manager will have overall accountability for program delivery, cost, schedule, staffing, and customer relationships across two concurrent workstreams: development of the new shared platform and sustainment of existing legacy applications. This individual will serve as the primary point of accountability to the customer’s program office and agreements officer and will lead a multidisciplinary team of approximately 30–36 engineers, security professionals, and delivery leads through a fast-paced, milestone-driven modernization effort. This position is contingent upon Concept Solutions’ award of the contract. The anticipated start date is October 2026.
