About the role

Lead deployment and optimisation of SD-WAN solutions across global infrastructure to enhance WAN performance and reduce costs.
Architect and implement SDN solutions to drive network automation, centralised control, and scalability.
Design, deploy, and manage a high-performance global IP backbone ensuring interconnections with Mobile Network Operators (MNOs) and cross-continental data center connectivity.
Optimise network traffic using SD-WAN for intelligent routing and latency minimisation; leverage SDN for overall network efficiency.
Integrate modern solutions with cloud environments (e.g., AWS, OCI) to ensure high availability and low-latency connectivity.
Implement security policies for SD-WAN, Zero Trust models, VPNs, and firewalls ensuring compliance with industry standards.
Collaborate with business units and cross-functional teams to deliver network solutions and ensure seamless service delivery.
Leverage automation tools (Terraform, Ansible, SD-WAN controllers) to streamline deployment and optimise configurations.
Monitor, analyse, and improve network performance using SD-WAN analytics and SDN monitoring tools.
Maintain thorough and up-to-date network documentation and report on performance, scalability, and security to stakeholders.
