Network Automation Engineer (Private Cloud)
Job Overview:
This is a fantastic opportunity to join a newly formed Private Cloud team. We are responsible for the design, deployment and operations of a new greenfield on-prem private cloud based on OpenStack. The Private Cloud Network Automation Engineer will develop the software, automation and Infrastructure as Code that will act as the glue to seamlessly provision networking capabilities within the OpenStack platform and integration with the underlying fabric. The role sits at the intersection of networking and software engineering and will help ensure day one operations are fully automated, scalable and consistent.
Responsibilities:
- Help establish zero-touch provisioning and automated network lifecycle by building reusable automation modules using Python, Ansible, APIs and Terraform tooling to automate the provisioning, configuration and integration of OpenStack networking services Neutron, OVN and ML2 with the network fabric.
- Develop CI/CD pipelines for network configuration and changes. Implementing automated testing and validation of network changes to ensure changes are version controlled, peer reviewed, tested and auditable.
- Integrate network automation with source control, IPAM, inventory and other platform systems, developing automated configuration compliance and drift detection.
- Develop telemetry and observability integrations and dashboards to enable easy debugging, solving and tuning opportunities.
- Work with Compute, Storage and Kubernetes engineers to automate end-to-end network workflows.
