SENIOR NETWORK ENGINEER

About the role

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.

Responsibilities

• 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), ExpressRoute, 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.
• Manage ISP and carrier relationships — including circuit procurement, SLA management, and fault escalation for connectivity issues.
• Maintain thorough, up-to-date network documentation including topology diagrams, IP address management (IPAM), configuration standards, and operational runbooks.
• Work closely with IT, Infrastructure, and Security teams on cross-functional projects, providing network expertise and ensuring dependencies are well-managed.
• Act as the senior technical authority on networking — mentoring junior team members, reviewing proposed changes, and setting the standard for how network work is planned and executed.
• Contribute to technology roadmap discussions, helping shape the long-term direction of ATG Entertainment's network strategy.

Qualifications

• 5–8 years of experience in a network engineering role, with a proven track record of managing complex, multi-site network environments.
• Deep expertise with Cisco routing and switching — including configuration, troubleshooting, and lifecycle management of Cisco hardware in enterprise environments.
• Hands-on experience administering Cisco Meraki — including switches, wireless access points, and security appliances via the Meraki dashboard.
• Strong working knowledge of Microsoft Azure networking — including VNets, ExpressRoute, Azure Firewall, NSGs, and Azure DNS.
• Experience managing Microsoft NPS for RADIUS authentication and network access control.
• Proven experience with SD-WAN design and operations — including traffic policy, link failover, and performance optimization across multiple sites.
• In-depth knowledge of networking protocols and technologies: BGP, OSPF, EIGRP, STP, VLANs, QoS, MPLS, and IPsec.
• Strong firewall management experience — policy design, auditing, and ongoing governance across a multi-site estate.
• Experience designing and managing enterprise wireless infrastructure for high-density, multi-site environments.
• Solid understanding of network security principles — including segmentation, access control, VPN architecture, and zero-trust concepts.
• Excellent documentation skills — able to produce clear topology diagrams, runbooks, and technical standards.
• Strong communicator — able to translate complex network concepts for non-technical stakeholders and collaborate effectively across teams.
