Senior Solutions Architect Fairfax, Virginia - Hybrid

DSA Inc. is a mission-focused information technology innovator supporting the Department of Defense (DoD), Department of the Army/DoW, the Intelligence Community (IC), and Federal Civilian agencies. DSA’s work spans AI-enabled software development, cyber modernization, C5

ISR sustainment, LCNC automation, digital engineering, and enterprise IT transformation. Our mission is to accelerate modernization and readiness across critical national security environments.

The Senior Solutions Architect leads the design, development, and delivery of advanced technical solutions for Defense, Intelligence, and Federal Civilian customers. This role is both strategic and hands‑on—owning solution strategy, customer engagement, architecture development, proposal leadership, and mentoring team members.

The Senior SA serves as a technical thought leader, translating mission needs into resilient, scalable, secure architecture. This position is expected to independently drive solution development efforts, guide early‑phase capture activities, and ensure solution integrity across complex multi‑domain pursuits. Over time, Senior SA will assume greater supervisory responsibilities and may manage a small team of Solution Architects and technical contributors.
