Mission Systems Director

About the Role

We are looking for a senior acquisition leader to join Vannevar to shape long-cycle opportunities across PEOs and major program offices. This role is central to Vannevar’s pivot into PEO-first growth. You will bring first-hand experience on how programs are built, funded, fielded, integrated, and sustained to help Vannevar shape the next generation of capabilities.

As part of our Mission Systems organization, your insights into PEO structures, program office decision-making, acquisition timelines, budgeting, and integration challenges will guide how we shape requirements, build relevance early, and position Vannevar to win large, durable programs. This is a unique opportunity for a former PEO, Deputy PEO, Major PMO Lead, or Senior Program Manager who wants to apply their operational and acquisition experience inside a fast-moving national security startup that is building tools directly aligned to the needs of the military.

U.S. Persons status with at least a current Top Secret US DoD or IC clearance is required.

Build trusted customer relationships

• Leverage your network across PEOs, PMWs, and partner organizations to open doors, deepen trust, and accelerate customer understanding.
• Engage senior acquisition leaders to understand real-world constraints, mission needs, and where Vannevar’s technology can be most impactful.
• Navigate program offices with fluency—knowing who the decision-makers are, how they think, and how programs actually move.

Guide capture, shaping, and competitive positioning

• Partner with the Senior Growth Lead to influence requirements early, shape concept of operations, and ensure our offerings align to program office needs.
• Provide technical, operational, and programmatic context that positions Vannevar uniquely versus primes, integrators, and other emerging vendors.
• Support bid/no-bid calls, capture strategy, teaming strategy, and pr
