You will lead and scale our Department of Defense (DoD) IL5 SaaS and enclave security program. As the ISSM, you’ll drive the Risk Management Framework (RMF) lifecycle from initial categorization through Authorization to Operate (ATO) and continuous monitoring. You’ll partner with engineering to implement IL5-specific controls, enforce STIG/SRG compliance, and ensure our enclave is audit-ready. You will serve as the primary interface with Authorizing Officials (AOs), Security Control Assessors (SCAs), and government stakeholders, while coaching a small team to deliver sustained security excellence.
