Cape Town, Western Cape, South Africa EXL Full time US$70 000 - US$130 000 per year
Description

We are seeking an experienced Network Manager to lead the design, development, and deployment of next-generation network solutions. This role requires strong expertise in infrastructure automation, SDWAN technologies, and secure cloud networking frameworks such as SASE and ZTNA. The ideal candidate will integrate networking workflows into DevOps practices while collaborating across engineering, security, and business teams.
 

Responsibilities

1) Network Automation & Orchestration: Develop low-level automation using Ansible, Terraform, Python, and Puppet to configure routers, switches, firewalls (Cisco, Arista, Palo Alto), and enforce policy-driven changes across hybrid environments.

2) Core Network Engineering: Hands-on expertise in Layer 2/3 protocols (MPLS, BGP, OSPF, VRRP, STP, VLANs) and physical/logical infrastructure design for large-scale, multi-region enterprise networks.

3) Infrastructure as Code (IaC): Implement version-controlled, repeatable network provisioning using Terraform modules, YAML-based configs, and Git workflows to manage complete network lifecycles.

4) Cloud Network Provisioning: Automate and manage cloud-native networking (VPCs, subnets, route tables, VPNs, Direct Connect, Transit Gateway, firewalls, NACLs, Security Groups) in AWS, Azure, and GCP.

5) CI/CD for Network Ops: Integrate network changes into CI/CD pipelines (Jenkins, GitLab CI) for test-driven deployments with linting, validation, rollback, and minimal operational downtime.

6) Internet & Perimeter Security: Configure and manage internet-edge security layers (firewall policies, DDoS protection, IPS/IDS, web proxies) and ensure secure ingress/egress traffic flows.

7) Monitoring, Telemetry & Auto-Remediation: Deploy NMS/telemetry tools (SolarWinds, Prometheus, InfluxDB) and write custom scripts for real-time alerting, anomaly detection, and event-driven remediation.

8) Troubleshooting & Packet Analysis: Perform low-level debugging using packet captures (Wireshark/tcpdump), flow telemetry, syslog, and routing table state analysis to resolve incidents in multi-vendor networks.

9) Cross-Functional Collaboration & Documentation: Collaborate with CloudOps, DevOps, Security, and platform teams to align network architecture with application needs. Maintain up-to-date HLD/LLD, runbooks, topology maps, and compliance records.

10) Innovation & Optimization: Evaluate SDN, SASE, Zero Trust, and AI-based networking solutions to continuously improve agility, reliability, and performance of the network ecosystem.
