Responsibilities

Datacenter & Availability Zone Architecture

• Architect spine-leaf fabrics leveraging EVPN-VXLAN for scalable L2/L3 segmentation.
• Design multi-AZ topologies enabling 3ms synchronous replication, active/active distribution, and clean-room isolation for critical workloads.
• Engineer 100/400GbE connectivity with DWDM integration for metro and regional datacenter interconnects.
• Produce end-to-end design packages: logical/physical topologies, routing policy, security zoning, and DR strategy.

Juniper Specialization

• Lead fabric automation and lifecycle operations using Juniper Apstra.
• Deploy Juniper QFX series for EVPN/VXLAN overlays and PTX series for DC interconnect and WAN edge.
• Integrate SRX firewalls with AppSecure, IDP, and Zero Trust for north-south and east-west security.

• Integrate Aruba Central for cloud-based operations, AI-driven assurance, and policy enforcement.
• Align solutions with Zero Trust Networking (ClearPass, NAC, Dynamic Segmentation).

Resiliency, DR, and Multi-Cloud

• Design WAN edge leveraging Juniper Contrail SD-WAN and Aruba Edge Connect SD-WAN for hybrid/multi-cloud access.
• Implement business continuity topologies with active/active and active/passive designs across AZs and DCs.
• Define clean-room strategies isolating critical workloads for ransomware-resilient DR.

Automation & Observability

• Deploy telemetry-based observability (gNMI, streaming telemetry, NETCONF/YANG).
• Implement network observability stacks with Apstra, Aruba Central AIOps, and NetEdit.
• Build IaC pipelines with Terraform, Ansible, and Python for repeatable deployments.

Required Skills & Experience

• 10+ years designing and deploying enterprise-scale datacenter networks.
• Expert knowledge of Juniper QFX/PTX/SRX platforms and Apstra automation.
