This opportunity is in anticipation of a future contract award!

What you’ll be doing:

• Protect organization's critical systems, data, and networks from advanced cyber threats.

• Lead security operations center (SOC) teams or incident response efforts, ensuring effective coordination and communication across stakeholders. 
• Conduct in-depth analysis of advanced persistent threats (APTs), zero-day vulnerabilities, and nation-state actors, providing actionable intelligence to leadership. 
• Develop and refine threat hunting strategies to proactively detect and mitigate potential attacks. 
• Oversee the end-to-end lifecycle of incident response efforts for high-severity security incidents, including containment, eradication, recovery, and post-incident analysis. 
• Lead forensic investigations to determine the root cause of incidents, identify Indicators of Compromise (IOCs), and assess the broader impact on systems. 
• Develop and maintain cybersecurity policies, playbooks, and incident response procedures in alignment with organizational and regulatory requirements. 
• Provide strategic recommendations to enhance the organization's overall cybersecurity posture and minimize risk. 
• Prioritize and assess vulnerabilities based on potential impact, criticality, and exploitability, and recommend remediation strategies to stakeholders. 
• Work closely with system architects and engineers to assess risks associated with new projects, technologies, or configurations. 
• Act as a liaison between the organization and external threat intelligence providers, law enforcement, and government agencies (e.g., FBI, DHS, or DoD counterparts). 
• Integrate threat intelligence into the organization's monitoring, detection, and response processes, ensuring proactive defenses. 
• Lead efforts to ensure compliance with frameworks like RMF, NIST SP 800-53, and FISMA for audits and system accreditations. 
• Prepare detailed reports and presentations for executive leadership, summarizing security events, metrics, and trends. 
• Evaluate and recommend new security tools and technologies to enhance detection, analysis, and response capabilities. 
• Develop custom scripts or tools (e.g., Python, PowerShell) for automating threat detection, log analysis, or incident response workflows. 
• Work with system architects, DevSecOps teams, and software developers to incorporate security requirements into system designs and software pipelines. 

What does Leidos need from me?
