Zachary Piper Solutions is seeking a Senior Security Control Assessor Representative (SCAR) to support a high-visibility National Security contract in Arlington, VA. This is a 100% onsite role designed for a cybersecurity expert capable of navigating the complexities of the Department of Defense (DoD) environment.
The Senior SCAR will play a critical role in evaluating system security posture and advising Authorizing Officials (AOs) on cutting-edge AI/ML and data-driven mission systems. You will be responsible for delivering independent risk determinations that support Authority to Operate (ATO) decisions, ensuring compliance while articulating real-world risk across complex enterprise environments. This position offers the chance to provide strategic advisory support to senior DoD leadership, Program Managers, and military officials on authorization outcomes and overall risk posture.
In this role, you will lead the execution of the Risk Management Framework (RMF), applying DoD methodologies to identify baselines and evaluate controls. Your day-to-day activities will involve developing Security Assessment Plans, executing control assessments, and producing comprehensive Security Assessment Reports. You will track POA&M activities, validate remediation efforts, and reassess residual risk to ensure continuous security.
You will also evaluate modern system architectures, analyzing network diagrams to assess security impacts across enterprise environments. This includes assessing security integration within DevSecOps pipelines, CI/CD workflows, and cloud-hosted systems (AWS, Azure, GCP). A key part of your mission is to brief stakeholders, presenting authorization status and risk recommendations to Senior Executive Service (SES) and military leadership.
Candidates must possess an active Top Secret clearance (SCI eligible required) and relevant certifications (IAT/IAM II). To apply, please submit your resume highlighting your experience with end-to-end A&A activities, GRC tools (eMASS, Xacta), and cloud compliance.
