Key Responsibilities- Execute delivery of a multi-phase Network 2.0 transformation, including design validation, staging, migration, integration, and service cutover
- Implement and support Arista-based data center fabric architectures, including EVPN/VXLAN, MLAG, and BGP-based designs
- Configure and integrate Palo Alto firewalls, including NAT migration, policy design, and Panorama management
- Support datacenter consolidation and interconnect design, including redundant circuits and VPN failover strategies
- Deploy and validate core, edge, and management network components aligned to defined architecture standards
- Implement:
- eBGP/iBGP routing at the edge
- OSPF underlay with MP-BGP EVPN overlay
- VRF segmentation across multiple security zones
- Lead staging and proof-of-concept validation, including failover testing, interoperability, and performance validation
- Migrate legacy configurations (e.g., Juniper) into new Arista and Palo Alto environments
- Execute phased integration and cutover activities with minimal service disruption
- Develop and execute service migration plans, including rollback strategies and validation procedures
- Perform post-cutover validation, ensuring routing convergence, security enforcement, and service availability
- Collaborate with client and ISP teams to coordinate change windows and integration activities
- Produce and maintain detailed technical documentation, runbooks, and validation reports
