- Use Arista CloudVision for orchestration, telemetry, and automated configuration management across global environments.
- Build and maintain network automation scripts using Python, Nornir, and Ansible, ensuring repeatability and alignment with infrastructure-as-code practices.
- Support large-scale hardware refreshes and migrations from Cisco to Arista, ensuring minimal downtime in production environments.
- Collaborate with global teams to align network delivery with broader CI/CD pipelines, and implement proactive monitoring and remediation frameworks.
- Provide senior-level L3 support, mentor junior engineers, and drive best practices in operational excellence.
- Strong hands-on experience with Arista EOS in complex enterprise or global data centre environments.
- Deep knowledge of routing protocols (BGP, OSPF, EVPN) and Multicast technologies.
- Demonstrated experience working with Arista CloudVision in both greenfield and brownfield deployments.
- Background in low-latency networks – ideally within financial services or other performance-critical environments.
- Proficiency in network automation using Python, Ansible, Nornir, and version control tools (Git).
