About The Position

Davidsons Warfighter Integration (WFI) team is looking for a cyber security professional that moves at the speed of the mission-not just operating as an afterthought or administrative checkpoint. We are seeking an experienced Information Systems Security Manager (ISSM) Lead in Huntsville, Alabama to establish, lead, and oversee cybersecurity activities across a diverse portfolio of advanced defense programs and technologies. This role will serve as the senior cybersecurity authority within WFI, leading the cyber team, shaping security processes, and ensuring systems achieve and maintain the authorizations required to operate in demanding Department of War environments. The ISSM Lead will oversee the development of Authority to Operate (ATO) and Authority to Connect (ATC) packages, manage cybersecurity risk throughout the system lifecycle, and serve as the primary interface with customers, Authorizing Officials, security stakeholders, and program leadership. This is not a position focused solely on compliance documentation. The ISSM Lead will work directly with systems, software, network, DevSecOps, and integration teams to build cybersecurity into solutions from the beginning. WFI supports a fast-paced and evolving technology portfolio, giving this individual broad exposure to Command and Control, tactical networks, data fusion, cloud and edge computing, embedded systems, sensors, and other emerging warfighter technologies. The ideal candidate combines strong RMF expertise with the leadership, judgment, and communication skills required to turn cybersecurity requirements into executable engineering actions.
