• Analyze and operationalize threat intelligence sources, including CVE databases and CISA KEV catalog, to prioritize remediation and strengthen defenses against actively exploited vulnerabilities
• Perform vulnerability assessments using tools such as Tenable Nessus and web application scanners, and triage findings to reduce false positives/negatives
• Utilize Microsoft Defender Antivirus (MDAV) and endpoint detection tools to monitor, detect, and respond to threats across endpoints
• Collaborate with Dev Sec Ops , infrastructure, and development teams to incorporate security controls and automated scanning (SCA, SAST, DAST) into CI/CD pipelines and SDLC practices
• Develop and maintain SIEM solution, such as Splunk, for queries, dashboards, and reports to identify trends, detect anomalies, and highlight control gaps
• Support continuous monitoring and improve detection capabilities across hybrid enterprise environments, including on‑premises, cloud, and containers.
• Contribute to enterprise security architecture, including identity and access management and cloud security design
• Develop clear technical documentation, including assessment reports, mitigation strategies, and implementation guidance
• Stay current on emerging threats, vulnerabilities, federal cybersecurity directives, and industry best practices

• Bachelor's degree in Computer Science, Cybersecurity, Software Engineering, or related field (or equivalent experience)
• 4+ years of experience in cybersecurity, vulnerability management, systems engineering, or related fields
• Strong experience with vulnerability management programs, including risk prioritization using CVSS, threat intelligence, and exploit data (e.g., CVEs, CISA KEV)
• Working knowledge of Dev Sec Ops  practices and integrating security into CI/CD pipelines
• Hands‑on experience with Microsoft Defender Antivirus (MDAV) and endpoint security solutions
• Experience with vulnerability scanning and assessment tools (e.g., Tenable Nessus, web application scanners)
• Familiarity with cloud environments (AWS, Azure, or GCP) and containerized…
