What you'll do
- Lead technical implementation across Zero Trust, IAM, SIEM/EDR/XDR, vulnerability management, cloud security, network segmentation, security baselines, and incident response.
- Implement and maintain enterprise security controls aligned to NIST SP 800-53 and NIST SP 800-207 — access control, configuration management, system and communications protection, audit and accountability, incident response, and system and information integrity.
- Drive Zero Trust enforcement, continuous verification of users and devices, identity-centric security, and least-privilege access (RBAC, PAM, MFA).
- Oversee centralized logging and SIEM integration, vulnerability assessment, RMF-aligned risk analysis, system hardening, and AWS/Azure cloud security.
- Support incident response, forensic data collection, root cause analysis (RCA), change management, and automated patching.
- Produce SOPs, security impact analyses, implementation plans, validation criteria, rollback steps, and audit-ready control evidence.
- Collaborate with network, cloud, application, and service desk teams to remediate risk and strengthen posture.
- 10 years of hands-on enterprise cybersecurity experience, including federal or highly regulated environments.
- Demonstrated experience as a senior cybersecurity engineer or security architect leading technical implementation across multiple security domains.
- Proven track record configuring IAM and least-privilege controls; tuning SIEM/EDR/XDR alerts; conducting incident triage and containment; coordinating vulnerability remediation; and hardening cloud or hybrid environments.
- Strong technical writing — recommendations, implementation plans, validation criteria, and control evidence.
