Overview

DLH is seeking a highly skilled Senior Cyber Security Engineer to support a federal client in Bethesda, MD. This role focuses on strengthening enterprise cybersecurity posture through a combination of vulnerability management, secure engineering practices, DevSecOps integration, and advanced threat detection, while incorporating Zero Trust principles as part of a comprehensive defense strategy in multi-tenant cloud and on-premises environments.

The ideal candidate should be self-motivated and able to take ownership of workflows

They will bring experience identifying and prioritizing risk across enterprise systems, applying defense-in-depth principles across platforms, and leveraging security tools and threat intelligence (including CVE and CISA Known Exploited Vulnerabilities (KEV)) to proactively mitigate threats.

This role requires strong collaboration across security, infrastructure, and development teams, as well as the ability to communicate technical findings to both technical and non-technical stakeholders.

Responsibilities

• Integrate Zero Trust Architecture into enterprise environments through gap analysis, security maturity assessments, and risk-based control implementation
• Contribute to enterprise security architecture, including identity and access management and cloud security design
• Lead and support vulnerability management efforts, including identification, prioritization, and remediation of vulnerabilities based on risk, exploitability, and business impact
• Analyze and operationalize threat intelligence sources, including CVE databases and the 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 DevSecOps, infrastructure, and development teams to incorporate security controls and automated scanning (SCA, SAST, DAST) into CI/CD pipelines and SDLC practices
• Develop and maintain a 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.
• 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

Qualifications

• Bachelor’s degree in Computer Science, Cybersecurity, Software Engineering, or related field with a minimum of 10 years of experience; or Master’s degree in Computer Science, Cybersecurity, Software Engineering, or related field with a minimum of 6 years of experience; or High School Diploma with a minimum of 12 years of relevant experience.
• 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 DevSecOps 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 applications (ARO, Kubernetes)
• Experience with SIEM platforms such as Splunk for detection and analysis
• Strong understanding of security frameworks and compliance standards (NIST SP 800-53, 800-171, 800-37, FedRAMP, FISMA, ISO 27001, CIS Benchmarks, DISA STIGs)

• Working knowledge of AI security risk management frameworks and the ability to translate AI/ML use cases into security controls, review checkpoints, and governance decisions
• Strong analytical, problem-solving, and communication skills
• Active Public Trust Clearance walking through the door
