• Design, build, and maintain automation solutions for network and infrastructure systems.
• 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 ServiceNow, NetBox, and GitHub.
• Drive network configuration standardisation using YANG models for routers and switches.
• Implement and maintain CI/CD pipelines (GitHub Actions / Azure DevOps) 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.

Core Technologies

• Automation & Orchestration: Ansible, Cisco NSO, Terraform, GitOps (GitHub / GitLab / Azure DevOps)
• Networking & Modelling: YANG, RESTCONF, NETCONF, XML, JSON, Jinja2, NetBox
• Cloud & Platform: Azure, AWS, RedHat Enterprise Linux, VMware, OpenStack
• Scripting & Languages: Python, Bash, YAML (Go / PowerShell desirable)
• CI/CD & Tooling: GitHub Actions, Azure Pipelines, Jenkins, Terraform, ServiceNow

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 (RedHat, CentOS, Ubuntu).
• Knowledge of cloud networking (Azure / AWS VPCs, Transit Gateways, VPNs).
• Excellent documentation, troubleshooting, and stakeholder communication skills.
• Certifications such as Cisco CCNP / DevNet Professional preferred; ITIL desirable.

What You’ll Work On

• Standardising and automating global network configurations and connectivity services.
• Integrating network provisioning with ServiceNow and NetBox.
• 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 DevOps Engineer, or DevNet 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.If you're interested and keen to find out more, please apply now with your updated CV and reach out to Tom Johnson at Certain Advantage - Ref: 79585
