About The Position

The Service Delivery Center is made up of high-performing, US-based resources who work closely with our experienced professionals to deliver project-based work and managed services to our federal clients. The Service Delivery Center is a core component of the Government & Public Sector practice (GPS). This role is part of our Cybersecurity – Strategy, Risk, Compliance & Resiliency (“SRC&R”) team within our Service Delivery Center. This team assists our clients with aligning a security management strategy with their business goals by assessing, designing, training, implementing and operating cybersecurity processes and solutions. This function is supported by our strategic alliances with third-party vendors and leveraging cybersecurity frameworks (e.g. NIST CSF, NIST 800-53r5, NIST 800-37r2). The Senior Analyst provides Information System Security Officer (ISSO) and Security Control Assessment (SCA) support across the NIST Risk Management Framework lifecycle, including control assessment, security documentation development, boundary determination support, POA&M management, and continuous monitoring, while coordinating assigned workstreams and reviewing Analyst work products. A strong candidate should be able to prepare systems for assessment, coordinate evidence and remediate findings and describe RMF decisions and outcomes, while explaining when ISSO and SCA independence must be preserved.
