Responsible for delivering cybersecurity engineering services with a focus on email security and endpoint protection, including design, implementation, and continuous improvement across Proofpoint, Microsoft 365/O365, Microsoft Defender, and CrowdStrike:
• Plan, implement, configure, upgrade, and monitor security controls protecting enterprise networks, endpoints, and collaboration/email platforms (Proofpoint, O365, MS Defender, CrowdStrike).
• Engineer and maintain email security capabilities including anti-phishing, malware detonation/analysis, impersonation protection, URL/attachment defense, and policy tuning; support improvements to mail flow and authentication (e.g., SPF/DKIM/DMARC alignment as applicable).
• Engineer and maintain endpoint security (EDR/NGAV) capabilities including prevention policies, detection tuning, containment workflows, device isolation/quarantine procedures, and fleet-wide deployment/health monitoring.
• Assess vulnerabilities and security risks across email and endpoint ecosystems; propose, implement, and validate risk mitigation strategies (hardening, policy updates, rule tuning, and control coverage improvements).
• Ensure appropriate security controls and governance are in place to safeguard digital files and critical infrastructure, including configuration baselines, access controls, and monitoring/telemetry standards.
• Respond to security incidents (phishing, account compromise, malware, ransomware, endpoint outbreaks) by coordinating triage, containment, eradication, recovery, and lessons learned—leveraging Defender and CrowdStrike response actions and Proofpoint intelligence/workflows.
• Integrate and optimize tooling outputs (alerts, logs, and threat intelligence) across platforms to improve detection fidelity, reduce false positives, and enhance operational response (including workflow automation where applicable).
• Support year-round tracking, reporting, and guidance for POA&Ms and CMMC assessments, including control implementation evidence, remediation planning, and ongoing control effectiveness validation for email and endpoint security domains.
At Nightwing, we value collaboration and teamwork. You’ll have the opportunity to work alongside talented individuals who are passionate about what they do.
