COMPENSATION:
Commensurate with Experience

As a Senior Network Engineer at ATG Entertainment, you will take end-to-end ownership of our network infrastructure — spanning design, deployment, and day-to-day operations across our multi-site estate of offices and entertainment venues. Our network is the backbone of everything we do, and this role is central to keeping it fast, secure, and resilient across every location.

This is a senior, hands‑on role that sits at the intersection of architecture and operations. You will design and improve our network environment while remaining deeply involved in its daily management — responding to issues, driving performance, and championing best practices. You will work closely with our IT, Infrastructure, and Security teams, contributing your expertise to cross‑functional projects and serving as the go‑to authority on all things networks.

The ideal candidate brings deep experience across Cisco hardware and Meraki‑managed environments, strong knowledge of Azure networking, and a track record of managing complex, multi‑site networks with high reliability standards. You are as comfortable drawing up a network design as you are troubleshooting a live issue on the floor of a venue.

• Own the design and continuous evolution of ATG Entertainment's network architecture across all office and venue locations — ensuring it is scalable, resilient, and aligned with business growth.
• Develop and maintain network standards, design patterns, and documentation that serve as the authoritative reference for how our network is built and operated.
• Evaluate new networking technologies, solutions, and vendors — making evidence‑based recommendations that improve capability, reduce complexity, or lower cost.
• Design and implement network segmentation strategies including VLANs, access control lists, and micro‑segmentation to support security and operational requirements.
• Lead network‑related planning for new venue openings, office buildouts, and major infrastructure changes — from initial design through to go‑live.

• Administer and maintain Cisco routing and switching infrastructure across all sites, ensuring consistent configuration, performance, and availability.
• Manage the Cisco Meraki platform — including switches, wireless access points, and security appliances — using the Meraki dashboard to monitor, configure, and troubleshoot the environment.
• Oversee Azure networking services including Virtual Networks (VNets), Express Route, Azure Firewall, Network Security Groups, and Azure DNS — maintaining alignment with our cloud infrastructure team.
• Manage Microsoft NPS (Network Policy Server) for RADIUS‑based authentication and network access control across wired and wireless environments.
• Respond to and resolve network incidents with urgency and precision — conducting root cause analysis and implementing preventative measures to reduce recurrence.

• Own firewall policy management across the estate — reviewing, updating, and auditing rules to ensure the network perimeter remains secure and well‑governed.
• Design and administer VPN infrastructure for site‑to‑site and remote access connectivity, ensuring secure and reliable access for users across all locations.
• Collaborate closely with the Security team to implement and enforce network security controls — including intrusion detection, traffic inspection, and zero‑trust network access principles where applicable.
• Conduct regular security reviews of network configurations, access controls, and firewall policies — proactively identifying and remediating risks.

• Manage and optimize WAN connectivity across all sites, including SD‑WAN configuration, link failover, and traffic prioritization to ensure consistent performance.
• Design, deploy, and maintain wireless infrastructure across offices and venues — ensuring reliable, high‑density Wi‑Fi coverage that meets the demands of staff and guests.
