Job description

Categorizes systems (FIPS 199) in coordination with system owners, accounting for high-volume PII/NPI data aggregation risks inherent to organizational data.
Build the control package: apply NIST SP 800-53 controls, develop the SSP, draft implementation statements, and collect evidence validating secure data ingestion and processing.
Guide system owners on writing and resolving implementation statements.
Drive controls to secure status and see them through testing, with emphasis on data integrity, encryption-in-transit (TLS), and Identity & Access Management (IAM).
Partner closely with the Security Assessment Provider/SCA to ensure quality of artifacts and evidence to enable the assessment.
Advise system owners on control prioritization, ensuring alignment with both NIST frameworks and financial regulatory data protection standards (e.g., FFIEC expectations).
Support RMF & A&A: Cyber Risk Framework (CRF) input, Change Request Reviews, POA&M tracking, SA&A Project List, and SOPs/A&A artifacts on a best-effort basis.

Requirements

Hands-on experience with NIST RMF (800-30, 800-37, 800-53, and 800-53A) - practical implementation, not just familiarity.
Demonstrated experience building control packages and drafting implementation statements.
Experience in creating or supporting Security Assessment Plans and Security Assessment Reports.
Experience with Q-Compliance (or the ability to ramp quickly).
Experience interpreting data from vulnerability scanning tools (e.g., Tenable, Qualys) to identify risks in databases and file-processing pipelines.
Understanding network architectures, including SaaS, IaaS, or PaaS environments; experience securing modern, cloud-native web platforms preferred.
Technical background sufficient to collaborate with system owners on design documentation.
SME-level knowledge of NIST SP 800-137 (ISCM).
1+ years of technical experience with Python, Java, or PHP - sufficient to read, interpret, and understand code to independently verify control implementation and evaluate technical alternate solutions for complex NIST requirements.
1+ year of experience with a GRC tool (such as CSAM).
Experience with Q-Compliance and/or Q-Audit.
Experience with API testing (REST APIs), JSON payload security, and/or scripting and automation.
Relevant industry certifications (e.g., CISA, CAP, CISSP, Security+).
Must be a U.S. Citizen with the ability to obtain and maintain a Public Trust clearance prior to starting this position.
Must be able to remain in a stationary position 50% and constantly operate a computer and other office productivity machinery, such as a calculator, copy machine and computer printer.
