• Independently perform complex reviews, including significant and critical findings and full system security plan reviews, with minimal oversight.
• Perform peer review of Level I analyst work, and provide guidance on control requirements and consistent determinations.
• Maintain complete and accurate records of all correspondence and documentation in the customer’s case management system.
• Comply with all customer security, privacy, and records management requirements, using only Government-furnished equipment and approved systems.

• Demonstrated experience, whether professional, internship, or academic, identifying and applying information security or cybersecurity requirements.
• Working knowledge of NIST SP 800-53 and the NIST Risk Management Framework, including how security controls are implemented and evidenced.
• Ability to read technical evidence, such as configuration screenshots, audit logs, and policy documents, and judge whether a control requirement has been met.
• Familiarity with common technologies that drive compliance questions, including cloud services, multifactor authentication, encryption, operating systems, and network devices.
• Strong technical writing skills, with the ability to produce clear, consistent, and well-supported written determinations.
• Proficiency with Microsoft Word and Excel; experience with VBA macros is preferred.
• Detail-oriented self-starter who takes ownership of assignments, manages competing priorities, and drives work to completion with minimal supervision.
• Preferred Certifications (not required):
