Role Overview:We are seeking a Network Architect with deep expertise in datacenter design, multi-availability zone architectures, and enterprise-grade fabrics. This role requires specialization in Juniper Networks and Aruba (HPE) latest product portfolios, with proven ability to design, scale, and secure next-generation infrastructures supporting high availability, low-latency replication, and hybrid cloud workloads.
Key Responsibilities:- 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.
- 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.
- Automate provisioning and operations using JunOS automation (PyEZ, Ansible, REST APIs).
- Architect Aruba CX 10000 with Pensando DPUs for distributed firewalling, service insertion, and micro segmentation.
- Deploy Aruba CX 9300/8400 for campus and datacenter spine-leaf roles.
- Leverage Aruba Fabric Composer for automated network virtualization and multi-tenant segmentation.
- Integrate Aruba Central for cloud-based operations, AI-driven assurance, and policy enforcement.
- Align solutions with Zero Trust Networking (ClearPass, NAC, Dynamic Segmentation).
- Design WAN edge leveraging Juniper Contrail SD-WAN and Aruba EdgeConnect 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.
- Deploy telemetry-based observability (gNMI, streaming telemetry, Netconf/YANG).
- Implement network observability stacks with Apstra, Aruba Central AIOps, NetEdit.
- Build IaC pipelines with Terraform, Ansible, and Python for repeatable deployments.
Required Skills:- Expert knowledge of Juniper QFX/PTX/SRX platforms and Apstra automation.
- Expert knowledge of Aruba CX 10000, CX 9300, CX 8400, Fabric Composer, and Central.
- Deep expertise in EVPN-VXLAN, BGP, IS-IS, OSPF, Segment Routing, and DWDM.
- Strong understanding of multi-AZ architectures, synchronous/asynchronous replication, and DR topologies.
- Proven skills in network security, including AppSecure, IDP, and Zero Trust principles.
- Experience with JunOS automation using PyEZ, Ansible, and REST APIs.
- Proficiency in building IaC pipelines with Terraform, Ansible, and Python.
- Familiarity with telemetry-based observability using gNMI, streaming telemetry, Netconf/YANG.
Qualifications:- 10+ years designing and deploying enterprise-scale datacenter networks.
