Join GDIT as a Senior Cybersecurity Engineer and take ownership of mission-critical cybersecurity programs that protect Department of Defense (DoD) systems. You'll be the go-to technical authority, leading security design, risk assessments, and authorization strategies across diverse, high-impact environments.

As a senior team member, you’ll work independently and collaboratively, mentor junior engineers, and drive system accreditation from strategy through execution — delivering proactive security and continuous compliance in support of national defense.

What You’ll Do:

• Lead the development, assessment, and authorization (A&A) of complex DoD systems following RMF processes (including DAAPM 2.2, JSIG Rev 4, ICD-503).
• Own the creation and lifecycle management of RMF documentation (SSPs, POA&Ms, SCTMs, risk assessments, etc.).
• Guide teams through successful ATO/IATO achievement and ensure continuous monitoring and compliance across systems.
• Architect and implement advanced cybersecurity controls, ensuring resilience against evolving threats.
• Direct the deployment and administration of cyber tools (e.g., ACAS, SPLUNK, HBSS) and security platforms (e.g., eMASS).
• Lead vulnerability scanning and mitigation strategies while supporting incident response planning and readiness.
• Collaborate with technical leads, mission stakeholders, and leadership to develop secure, scalable solutions.
• Evaluate and enhance system hardening, configuration management, and patching processes.
• Act as a mentor to junior and mid-level engineers, cultivating a culture of knowledge sharing and technical growth.
• Track and integrate evolving cybersecurity trends, threat intelligence, and DoD security guidance.

Preferred Certifications (one or more):

• Security & Governance: CISSP, CCSP, CISM, CEH, CAP
• Cloud & Platforms: AWS SysOps Administrator, Cloud+, Linux Essentials, SPLUNK
• Tools & Management: ITILv4, Project+, eMASS, HBSS, ACAS

Required Skills & Qualifications:

• Demonstrated leadership in cybersecurity architecture, RMF compliance, and system accreditation.
• Strong technical experience with vulnerability assessment, risk mitigation, and ATO lifecycle management.
• Fluency with DoD cybersecurity tools, processes, and secure configuration practices.
• Ability to lead projects independently, communicate security posture to technical and executive stakeholders, and influence secure design decisions.
• Proven experience supporting mission-driven environments, handling complexity and urgency with confidence.

At GDIT, your expertise shapes national security outcomes. We empower you to:

• Lead with autonomy and authority.
• Tackle meaningful, mission-first challenges.
