Senior Network Architect

MetroSys is seeking a highly skilled Senior Network Engineer to lead the implementation and delivery of a multi-phase network transformation initiative. This role is responsible for executing against a defined Statement of Work, including design validation, staging, migration, integration, and cutover activities for a next-generation network architecture.

The ideal candidate is hands-on, detail-oriented, and experienced in data center networking, routing, security, and large-scale migrations, with the ability to drive execution while maintaining alignment with architectural standards.

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

Required Qualifications

• 5–8+ years of experience in enterprise networking and infrastructure implementation
• Strong hands-on expertise with:
  • Arista EOS (EVPN/VXLAN, MLAG, BGP)
  • Palo Alto firewalls (policy, NAT, Panorama)
• Deep understanding of:
  • Routing protocols (BGP, OSPF)
  • Data center networking and segmentation (VRFs, VLANs)
  • High availability design (ECMP, BFD, clustering)
• Experience with network migrations, cutovers, and large-scale infrastructure transitions
• Ability to translate architecture into real-world configurations and execution plans
• Strong troubleshooting and validation skills across routing, security, and connectivity layers
• Experience working in client-facing or professional services environments
