We are seeking a forward-thinking Global Network Architect to design and lead the evolution of a next-generation, software-defined, and cloud-integrated global network. This role builds on strong enterprise networking fundamentals while advancing modern architectures such as SASE, Zero Trust, SD‑WAN, and cloud‑native networking, leveraging platforms including Cisco Catalyst, Cisco Meraki, and Zscaler. The incumbent will serve as a technical leader responsible for designing scalable, secure, and automated network solutions across corporate offices, venues (including arenas), and cloud environments, guiding the transition from legacy infrastructure to a fully software‑defined, policy-driven architecture.

• Lead the design and implementation of next‑generation enterprise network architecture, including LAN, WAN, cloud, edge connectivity, and smart spaces/venue intelligence network enablement.
• Drive transformation from traditional networking to SD‑WAN (Cisco Meraki / Catalyst SD‑WAN), SASE/Zero Trust (Zscaler ZIA/ZPA), and cloud‑native networking (AWS, Azure).
• Define standards for secure, scalable, and highly available network designs across global environments.
• Partner with business and technical stakeholders to ensure architecture aligns with company initiatives and growth.

• Oversee and maintain large‑scale enterprise networks including Cisco Catalyst, Cisco Meraki, internet connectivity, routing, and VPN solutions.
• Support venue wireless and in‑building wireless technologies (Wi‑Fi, BLE, DAS).
• Architect and support Layer 2/3 and Layer 4–7 services, including BGP, EIGRP, STP, load balancing, and traffic engineering.
• Design and optimize secure remote access and site connectivity using IPsec, SSL VPN, and Zero Trust approaches.

• Strong knowledge of Zero Trust Network Architecture using Zscaler and similar platforms.
• Integrate network security into architecture, including secure web gateways, cloud firewalling, and identity‑aware access controls.
• Ensure compliance with security best practices and enterprise policies, collaborating closely with data security teams.

• Drive network automation and infrastructure‑as‑code using Python, Ansible, APIs.
• Build and enhance monitoring, telemetry, and analytics platforms to track network performance, capacity, and utilization trends.
• Implement self‑healing and scalable operational processes.

• Act as a technical authority and mentor within the network engineering team.
• Provide hands‑on support, proof‑of‑concept development, and design validation.
• Collaborate cross‑functionally with cloud, security, and application teams.
• Promote innovation, continuous improvement, and knowledge sharing across teams.

• Core networking expertise in enterprise and broadcast (IP) network design and architecture.
• Strong experience with Cisco Catalyst (switching, routing, campus/core design) and Cisco Meraki (cloud‑managed networking, SD‑WAN, wireless).
• Advanced knowledge of BGP, EIGRP, STP, Layer 2–7 networking concepts, VPN technologies (IPsec, DMVPN, VTI, SSL VPN).
• Experience with wireless and smart‑venue technologies:
  Wi‑Fi, BLE, DAS.
• Modern networking & security experience with Zscaler (ZIA, ZPA) or equivalent SASE platforms.
• Strong understanding of Zero Trust architecture, SASE frameworks, secure access service edge design principles.
• Cloud & hybrid networking: working knowledge of AWS and/or Azure networking, integrating on‑prem networks with cloud environments.
• Automation & tooling proficiency in Python and/or Ansible, experience with network monitoring and observability tools, familiarity with APIs and infrastructure‑as‑code practices.
• Certifications (Preferred): CCNP/CCIE or equivalent; relevant cloud or security certifications (AWS, Azure, Zscaler).

• Strong problem‑solving and analytical thinking across complex systems.
