My client is seeking a Fully Remote Sr. Network Security Engineer SME to lead a high‑impact Zero Trust transformation for the FBI CJIS division, driving the shift from legacy network security to a modern, cloud‑first architecture powered by Zscaler.

• Configure and optimize Zscaler policies (URL filtering, SSL inspection, DLP, access controls) to meet security requirements
• Integrate Zscaler with enterprise identity providers (e.g., Active Directory, Azure AD) to enforce identity-based access
• Collaborate with cross-functional teams (network, security, cloud) to support Zero Trust and TIC 3.0-aligned architectures
• Manage and resolve complex network security issues, including traffic flow, access, and policy enforcement troubleshooting
• Support Operations & Maintenance (O&M) activities such as service ticket resolution, vulnerability remediation, and system sustainment
• Develop and maintain technical documentation, including architecture diagrams, implementation plans, and operational procedures

Required Qualifications:

• Hands-on experience with Zscaler (ZIA/ZPA) or comparable cloud security / SWG / ZTNA platforms strongly preferred
• 12+ years of network security or cybersecurity engineering experience required
• Education: A degree may substitute for a portion of the required experience
• Proven experience as a technical lead / SME on enterprise network or security projects
• Experience supporting large-scale network security migrations (e.g., proxy/VPN to cloud-based or Zero Trust architectures)
• Experience supporting Zero Trust architecture or modern secure access solutions
• Experience integrating with identity providers (Active Directory, Azure AD, SAML/OIDC)
• Strong background in enterprise networking and security, including firewalls (Palo Alto, Cisco, etc.), routing, DNS, and proxy architectures
• Experience with SIEM/logging platforms (Splunk preferred)
• Experience troubleshooting complex network and security issues in enterprise environments
• Day Shift 8am - 5pm
• Willingness to travel to Clarksburg, WV when required
• US citizenship Required

• Experience replacing on-prem forward proxies and/or VPNs with cloud-delivered security solutions
