About the Role

Project Engineers are the drivers behind execution. They connect program leadership with engineering teams, ensuring alignment, momentum, and results. In this role, you will lead and support cross-functional engineering efforts throughout the full design and development lifecycle, helping teams stay focused, coordinated, and moving toward a common goal.

On this team, you will play a key role in advancing projects centered on Open System Architectures for the Department of Defense (DoD). These architectures represent a rapidly evolving set of industry standards designed to modernize how hardware and software systems integrate. By enabling standardized interfaces across communication, sensor, and mission data systems, Open System Architectures allow for faster development, easier integration, and more agile deployment of new capabilities. If you are energized by working at the forefront of technology, enjoy learning and applying emerging capabilities, and want to contribute to mission-critical solutions that support the defense of the U.S. and its allies, this is an opportunity to make a meaningful impact.

This role is eligible for a sign-on bonus.
