Responsibilities:
Network Operations & Engineering
  • Own day-to-day operations, monitoring, and troubleshooting of on-premises and cloud-connected network infrastructure across global offices and data centers.
  • Lead incident response for complex network issues, performing root cause analysis and driving resolution with minimal supervision.
  • Manage global carrier services and connectivity across EMEA, APAC, and the Americas.
  • Maintain and improve operational documentation, including network diagrams, runbooks, and change records.
  • Participate in an after-hours/on-call rotation for critical incidents.

  • Lead network hardware and software lifecycle management, including capacity planning, patching, and firmware upgrades.
  • Evaluate new technologies and provide recommendations to senior architects.
Cloud & Hybrid Connectivity
  • Implement and support hybrid connectivity between on-premises environments and AWS/Azure, including AWS Direct Connect, Azure ExpressRoute, and VPN configurations.
  • Apply cloud networking concepts (VPCs, VNets, routing, security groups) to support both operational and project-level needs.
  • Collaborate with cloud and systems teams to ensure consistent and secure network integration across environments.
Automation & IaC
  • Actively develop and maintain Infrastructure as Code using Terraform and Git for network provisioning and configuration management.
  • Write and maintain scripts (Python, Shell, or PowerShell) to automate repetitive tasks and improve operational efficiency.
  • Contribute to CI/CD pipeline development and support the team's broader IaC adoption goals.
  • Serve as a practitioner-level resource for automation tooling within the network team.
Firewall & Security
  • Administer Check Point firewalls, including rulebase management, policy optimization, and VPN configuration.
  • Manage Aruba ClearPass NAC policies for network access control, authentication, and segmentation.
  • Ensure adherence to our network security standards across all environments and assist in driving compliance across the broader infrastructure.
Mentorship & Collaboration
  • Provide technical guidance and day-to-day mentorship to Network Engineers on the team.
  • Participate in design and architecture discussions, contributing operational insight and engineering perspective.
  • Collaborate cross-functionally with infrastructure, security, and cloud teams on shared initiatives.
Qualifications:
Required
  • Experience: Minimum of 6 years of enterprise networking experience in a hands-on engineering or operations role.
  • Networking Expertise:
    • Strong hands-on experience with Aruba and/or Cisco LAN, WAN, and wireless infrastructure.
    • Solid understanding of dynamic routing protocols (BGP, OSPF) and Layer 2 technologies (VLANs, STP, QoS).
    • Experience administering Check Point firewalls, including policy management and VPN troubleshooting.
    • Working knowledge of AWS and/or Azure networking (VPCs/VNets, routing, Direct Connect/ExpressRoute, VPN connectivity).
  • Automation & IaC:
