Network Administrator

Careerscape is recruiting on behalf of our client, a growing enterprise IT organization in Dallas, for an experienced Network Administrator to keep their LAN/WAN infrastructure fast, secure, and reliable. This hybrid role puts you at the center of daily network operations, from firewalls and VPNs to switches, routers, and uptime monitoring, giving you real ownership over the systems the whole business depends on.

Day to day, you will split time between hands-on troubleshooting, proactive maintenance, and quiet stretches of monitoring dashboards for anomalies before they become outages. The person who thrives here is calm under pressure, methodical about documentation, and genuinely enjoys tracing a connectivity issue back to its root cause rather than just patching symptoms.

Responsibilities

• Maintain and monitor LAN and WAN infrastructure across all office and hybrid locations
• Configure, manage, and troubleshoot firewalls, VPNs, and remote access solutions
• Monitor network performance and uptime, proactively identifying and resolving bottlenecks
• Respond to and resolve network incidents and outages within defined SLAs
• Manage switches, routers, wireless access points, and related network hardware
• Implement and enforce network security best practices and access controls
• Document network configurations, topology diagrams, and standard operating procedures
• Coordinate with vendors and ISPs on circuit issues, upgrades, and installations
• Support patch management, firmware updates, and network capacity planning
• Provide escalated network troubleshooting support to the broader IT team

Requirements

• 3+ years of experience administering enterprise LAN/WAN environments
• Hands-on experience configuring and maintaining firewalls and VPN solutions
• Solid understanding of TCP/IP, DNS, DHCP, and routing and switching fundamentals
• Experience with network monitoring tools and incident response
• Ability to troubleshoot complex connectivity issues under time pressure
• Familiarity with network security principles and access control practices
• Strong documentation habits and clear written communication
• Certifications such as CompTIA Network+, Security+, or Cisco CCNA are a plus
• Availability for occasional after-hours maintenance windows or on-call support

Benefits

• Medical, dental, and vision insurance
• 401k with employer match
• Paid time off and paid holidays
• Hybrid work schedule
• Life and disability insurance
• Professional certification and training reimbursement
• Employee assistance program
• Collaborative, hands-on IT team environment
• Career growth into senior network or infrastructure roles
