This role is designed for an experienced project leader who can operate with a high degree of autonomy, influence execution planning, and drive alignment across cross-functional teams.

This position carries significant responsibility and visibility and requires sound judgment, execution rigor, and the ability to partner effectively with senior program and functional leadership.

• Lead execution of multiple complex projects supporting a major defense program.
• Define and influence the integrated execution plan that underpins project schedules, cost baselines, and performance commitments, working closely with scheduling and project controls teams.
• Coordinate cross-functionally with engineering, manufacturing, supply chain, contracts, quality, logistics, and finance to ensure aligned execution.
• Identify, assess, and manage project risks and issues; develop, track, and drive mitigation actions to closure.
• Monitor project performance using schedule, cost, and risk indicators; ensure emerging issues are surfaced early with clear recommendations.

Preferred Qualifications

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.
