Prior experience as a chief engineer or technical authority on a program of record or major defense contract is essential. You must demonstrate strong capability in leading large-scale proposals, interfacing with senior government customers, and motivating teams across diverse organizations without direct line authority. Willingness to travel up to 25% and ability to work in classified environments 25%+ of the time are required.
