Senior Full Stack Application Developer

Leidos•Tampa, FL

About The Position

We’re looking for an experienced Senior Full Stack Applicatoin Developer to support a Contract Management Tool, a mission-critical platform designed to modernize financial planning, execution tracking, and audit readiness for the Department of Defense (DoD). This developer will be responsible for designing, building, and maintaining secure full-stack solutions that support program transparency, fiscal responsibility, and operational agility. At Leidos, we don’t want someone who "fits the mold"—we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, “what’s next?” before the dust settles on “what’s now.” If you’re already scheming step 20 while everyone else is still debating step 2… good. You’ll fit right in.
