Network Engineer - Public Trust

Network Engineer - Remote (U.S.)

Dunhill Government Solutions is hiring a Network Engineer to support a newly awarded federal program delivering enterprise identity and directory services. This is a full-time, fully remote role keeping the routing, switching and firewall layer healthy underneath authentication, authorization and directory replication traffic for a large federal user population.

Responsibilities:

• Configure, administer and maintain enterprise routers, switches, network segments and the supporting infrastructure behind identity and directory services.
• Implement and manage firewall rules, access control lists and network security controls that protect directory traffic without costing availability or performance.
• Troubleshoot connectivity issues affecting Active Directory replication, LDAP queries, DNS resolution and Kerberos authentication across distributed sites.
• Monitor network performance, availability, integrity and security; investigate alerts and carry out restoration and recovery for intermediate network issues.
• Work with directory services engineers to find root causes of authentication failures, replication delays and intermittent connectivity.
• Support capacity planning by evaluating peak authentication loads, replication demand and infrastructure growth.
• Keep network topology diagrams, VLAN structures, configuration records and security-zone documentation current for operational continuity and compliance audits.
• Take part in scheduled maintenance windows, change management, security assessments, testing and compliance validation.

Requirements:

• U.S. citizenship, and the ability to obtain and maintain a Public Trust (Tier 1 / NACI) background investigation.
• Bachelor's degree in computer science, information technology or a related field, or equivalent relevant experience.
• At least 3 years of hands-on network administration or network engineering experience; 2-5 years of network administration experience meets the standard minimum.
• Hands-on experience configuring and supporting enterprise routers, switches, LANs, WANs and related infrastructure.
• Working knowledge of TCP/IP, DNS, LDAP and Kerberos, including how network misconfiguration affects directory replication and authentication.
• Experience administering firewalls, access control lists and network security controls in an enterprise environment.
• Demonstrated ability to troubleshoot connectivity, performance and authentication issues with sound diagnostic practice.
• Preferred: CompTIA Network+ and/or Cisco CCNA or higher; experience supporting Microsoft Active Directory network environments; experience with security compliance validation in a federal or similarly regulated environment. Not holding a certification today does not stop you applying.
• Fully remote, day shift. Travel is not required.

Compensation: $90,000 to $108,000 per year, full time, 40 hours per week.
