About the Role
My client, within Financial Services, are looking for a Network Automation Engineer with deep, hands-on expertise across network automation, infrastructure-as-code and Python/Ansible-driven engineering. We're looking for a technical specialist to build and deliver production-grade automation across multi-vendor network environments, working directly in code, pipelines and playbooks.
You'll be hands-on building automation architectures, developing playbooks and scripts, and embedding validation into CI/CD pipelines. Working closely with the wider engineering team, you'll turn requirements into working automation, from initial design through to production deployment.
Key Responsibilities
- Design and build automation solutions across multi-vendor network environments (Cisco, Arista, Juniper).
- Develop and maintain Python scripts and Ansible playbooks/roles for configuration management and API-driven automation.
- Build and maintain infrastructure-as-code workflows using NetBox, Git and Jinja2 templating.
- Implement spec-driven development: write acceptance criteria before code, validate implementations against the spec.
- Embed pre- and post-change validation into CI/CD pipelines, using tools such as Robot Framework, pytest, pyATS/Genie or ANTA.
- Apply block/rescue/always and atomic-change patterns so rollback is always a first-class path.
- Integrate secrets management (Vault/CyberArk) so credentials are never hardcoded in code or inventory.
- Maintain documentation-as-code: runbooks, SOPs and architecture decisions version-controlled alongside the automation.
