Systems and Network Administrator

Responsibilities

• Design, deploy, and maintain a Cisco Meraki environment spanning MX security appliances, MS switches, MR wireless access points, and MV cameras — and keep it performing flawlessly as we grow.
• Own network health end-to-end: proactively monitor throughput and availability via the Meraki Dashboard, and hunt down bottlenecks and security events before they become problems.
• Architect and manage VLANs, DHCP, DNS, firewall rules, site-to-site VPNs, and traffic-shaping policies across both production and office environments.
• Build and maintain resilient cloud networking across Microsoft Azure (VNets, NSGs, ExpressRoute/VPN Gateways, Azure Firewall, Private Endpoints) and AWS (VPCs, Transit Gateway, Security Groups).
• Lead network expansions, office buildouts, and infrastructure refreshes — from whiteboard to production.
• Administer and harden Windows and Linux servers, owning patching, performance monitoring, and backup/recovery.
• Manage a diverse endpoint fleet across macOS, Windows, and Linux via Jamf Pro, Microsoft Intune, and supplemental Linux tooling — including configuration profiles, OS patching, compliance policies, and app deployment.
• Administer endpoint security tooling, including ThreatLocker and CrowdStrike, collaborating closely with IT Support on imaging, provisioning, and compliance enforcement.
• Manage physical security and AV systems, including Kisi access control and Envoy visitor management.
• Operate and optimize Zscaler ZPA and ZIA for zero-trust network access — tuning policies, monitoring connector health, and resolving client issues.
• Own IT asset tracking, network documentation, cloud topology diagrams, and MDM runbooks in Confluence — leaving things better than you found them.
• Write clean, maintainable automation in Bash, PowerShell, and Python to streamline operations, reduce toil, and improve visibility.
• Champion compliance efforts tied to Vanta, ITAR, NIST 800-171, and GCC-High — particularly around network segmentation, endpoint posture, and cloud security.
• Lead special projects from kickoff to completion, with full accountability for outcomes.

Qualifications

• Associate’s or Bachelor’s degree in IT, Network Engineering, Computer Science, or a related field — or equivalent experience that speaks for itself.
• 3+ years in network or systems administration with a meaningful networking focus.
• Demonstrated Cisco Meraki proficiency: security appliance policies, switch port configuration, SSID management, and client troubleshooting.
• Strong networking fundamentals: TCP/IP, DNS, DHCP, VLANs, 802.1X, spanning tree, routing, and Wi-Fi (802.11ax).
• Solid Azure networking knowledge (VNets, subnets, NSGs, VPN Gateways) and working familiarity with AWS (VPCs, Security Groups).
• MDM experience across macOS, Windows, and Linux — enrollment, configuration profiles, compliance, and patch management.
• Solid Windows and Linux server administration: patching, hardening, and service management.
• Self-directed and composed under pressure, with a track record of managing competing priorities without dropping the ball.
• Clear communicator who can translate technical complexity for any audience.
