Develop Ansible playbooks and reusable automation modules for configuration, orchestration, and provisioning.
Configure and integrate Cisco NSO and related orchestration tools to streamline network operations.
Build and maintain API-based integrations with systems such as Service Now, Net Box, and Git Hub.
Drive network configuration standardisation using YANG models for routers and switches.
Implement and maintain CI/CD pipelines (Git Hub Actions / Azure Dev Ops) for network code delivery.
Troubleshoot and optimise automation workflows across hybrid (on-prem and cloud) environments.
Collaborate with architects, service owners, and developers to translate requirements into scalable automated solutions.
Maintain documentation for designs, processes, and operational procedures.
Promote automation, standardisation, and best practices across global teams.

Experience & Requirements

Proven experience in network engineering or network automation (WAN, LAN, routing, switching, DNS, DHCP).
Hands-on experience developing automation using Ansible and Python.
Familiarity with Cisco NSO and YANG modelling or similar orchestration tools.
Understanding of network APIs (REST/NETCONF) and data formats (XML/JSON).
Experience integrating automation into CI/CD pipelines using Git-based workflows.
Comfortable working in Linux-based environments (Red Hat, CentOS, Ubuntu).
Knowledge of cloud networking (Azure / AWS VPCs, Transit Gateways, VPNs).
Excellent documentation, troubleshooting, and stakeholder communication skills.
Certifications such as Cisco CCNP / Dev Net Professional preferred; ITIL desirable.

What You’ll Work On

Standardising and automating global network configurations and connectivity services.
Integrating network provisioning with Service Now and Net Box.
Building the automation layer for hybrid cloud networks (Azure / AWS / on-prem).
Creating reusable playbooks, templates, and design artefacts for future deployments.
Supporting the organisation’s transition toward infrastructure-as-code and self-service provisioning.

Ideal Candidate
You’re an experienced Network Automation Engineer, Network Dev Ops Engineer, or Dev Net Specialist with hands-on expertise in both traditional networking and modern automation practices. You’re fluent in Python, think in APIs, and take pride in transforming manual configurations into efficient, repeatable code.
