RMF/ATO Expert for Federal Project

I'm the prime on an active federal website-modernization bid and need one RMF/ATO subject-matter expert as a named 1099 team member. Scope: independent review and QA of the security control statements and the ATO evidence package for a system on Microsoft Azure Government (FedRAMP), authorized at the Moderate impact level under the NIST Risk Management Framework (the agency is the Authorizing Official). Light and bounded: about 120 hours total across a ten-week build, fully remote, paid at your hourly rate. Must-have: you have PERSONALLY carried a federal system to a Moderate ATO under the NIST Risk Management Framework (as ISSO/ISSE/security lead), and can author or review a System Security Plan, an inherited/shared control-responsibility matrix, and a continuous-monitoring plan. Azure Gov / FedRAMP / civilian-agency A&A ideal. CGRC or CISSP and a clearance are pluses, not required. No facility clearance needed. Timing: this role is contingent on contract award (anticipated mid-July). I'm confirming availability and interest now; if we win, it's paid work at your rate.
