Governance, Risk & Compliance at the Core of Security

Security isn't just about defenses, it's about governance, risk, and compliance (GRC) as the foundation of mission success. As an ISSE, you will architect, implement, and maintain security controls that ensure compliance while strengthening the security posture of highly regulated, mission-critical environments. You'll navigate complex risk landscapes, driving the Authorization to Operate (ATO) process and securing systems against evolving threats.

The Role:

• Lead ATO efforts, ensuring compliance with NIST, RMF, FedRAMP, and other frameworks.
• Design and implement risk-based security controls across infrastructure, networks, and applications.
• Develop and maintain GRC documentation, including SSPs, risk assessments, and compliance reports.
• Serve as a trusted security authority, guiding teams through audits, risk mitigation, and regulatory assessments.
• Optimize security and compliance workflows, balancing strict requirements with operational agility.

What You Bring:

• Expertise in Governance, Risk & Compliance (GRC) as a core security function.
• Active TS/SCI with Polygraph clearance
• 5+ years in security engineering, compliance, or risk management.
• Deep knowledge of NIST 800-53, RMF, FedRAMP, and secure system accreditation.
• Hands-on experience with AWS, Azure, Kubernetes, Terraform, and security automation.
• Strong grasp of authentication, encryption, vulnerability management, and audit logging.
• Ability to translate complex security and compliance requirements into actionable solutions.
