SeniorSystemsEngineer

**ACTIVE TS/SCI SECURITY CLEARANCE REQUIRED** Think strategically. Deliver technically. Shape the architecture. At D2 Tech Services, Senior Systems Engineers aren’t order-takers — they’re the people who look at a complex, multi-site enterprise and figure out how to make it better. You’ll work across contracts and service lanes, translating technical reality into architecture artifacts, integration plans, and documented solutions that drive the mission forward. We’re looking for a self-aware, highly adaptive engineer who can communicate as fluently with leadership as with fellow engineers — someone who takes ownership, pursues continuous improvement, and brings eight years of enterprise-scale systems experience to a team that values all three.
