Corporate Resources

Unlike traditional ISSO positions that are primarily compliance and documentation focused, this role is backed by a broader cybersecurity and engineering organization. You will have access to a large cybersecurity laboratory environment, engineering resources, and reach-back subject matter experts across cloud, networking, identity, systems engineering, application security, vulnerability management, security operations, and federal cybersecurity compliance.

You will be able to use these resources to investigate technical issues, validate security approaches, reproduce and assess configurations, evaluate emerging technologies, and develop practical solutions to security and compliance challenges. The position offers an opportunity to lead not only the execution of RMF activities, but also to help shape the technical approaches, processes, tools, and practices used by the cybersecurity team.

Technical Environment and Professional Resources

You will be supported by capabilities beyond those normally available to an embedded ISSO team, including:

• Access to a dedicated cybersecurity and engineering laboratory for testing, validation, prototyping, and technical investigation
• Reach-back access to experienced cybersecurity, cloud, network, systems, identity, application, and infrastructure SMEs
• Opportunities to work directly with engineers to translate security findings and control requirements into implementable technical solutions
• Ability to evaluate and test security tools, configurations, architectures, and remediation approaches outside of the production environment
• Access to organizational lessons learned, technical expertise, reusable engineering approaches, and cybersecurity research developed across other federal programs
• Opportunity to help mature the team's RMF, continuous monitoring, vulnerability management, security engineering, and automation practices
• Ability to influence the technical direction and operating model of a growing federal cybersecurity team
