SeniorAdministrator - Wireless Networking

Job Summary

1. Core Networking Fundamentals TCP/IP stack (L2–L7 understanding) Routing & Switching Protocols: OSPF, BGP, EIGRP, IS‑IS VLANs, STP, EVPN, VXLAN WAN technologies MPLS, SD‑WAN, Internet VPNs IP addressing & design IPv4/IPv6, CIDR, summarization High availability & resiliency HSRP/VRRP, ECMP, load balancing QoS & traffic engineering 2. Network Design & Architecture Skills (Architect Core) Enterprise network design. Campus, Data Center, WAN, Cloud Reference architectures = Spine‑Leaf, 3‑tier, Clos Scalability planning, Capacity planning & growth modeling Redundancy & fault tolerance, Active‑active, DR, multi‑region Technology evaluation, Vendor comparison & design tradeoffs Documentation HLD (High‑Level Design), LLD (Low‑Level Design) Network diagrams (logical & physical). 3. Data Center & Cloud Networking Modern architects must be hybrid‑focused. Data Center - Spine‑Leaf architectures, VXLAN/EVPN, DC interconnect (DCI) Storage networking basics (iSCSI, FC – conceptual), Cloud Networking (AWS / Azure / GCP) VPC / VNet design, Subnets, routing tables, IGW, NAT, Hybrid connectivity. Site‑to‑Site VPN, ExpressRoute / Direct Connect, Cloud security groups & NACLs, Multi‑region & multi‑cloud design 4. Network Security Architecture: Architects design security by default, not as an add‑on. Perimeter & internal security Firewalls (NGFW), DMZ design, Zero Trust principles, Segmentation, VRFs, micro‑segmentation, Secure access, NAC (802.1X), VPN (Remote & Site‑to‑Site) DDoS mitigation concepts, Compliance awareness, ISO 27001, PCI‑DSS, SOC2 (design implications). 5. Automation & Programmability (Increasingly Essential) Not deep coding but designing for automation, Network automation concepts APIs & REST basics Tools & languages (working knowledge) Python, Ansible, Terraform (especially for cloud) SDN & controllers - Cisco ACI, VMware NSX, infrastructure as Code (IaC) mindset. 6. Tools & Technologies Hands‑on familiarity is expected. Network vendors Cisco, Juniper, and Arista. Monitoring & observability - SNMP, NetFlow, Telemetry, SolarWinds, PRTG, Grafana Diagramming & documentation - Visio, Draw.io, Lucid chart Troubleshooting - Wireshark, packet analysis (conceptual depth) 7. Soft Skills & Business Alignment (Critical) Architects operate at technical + executive levels. Stakeholder communication (IT & business) Translating business needs into technical design Risk analysis & trade‑off decisions, Vendor negotiation & RFP evaluation Presentation & design justification, Mentoring engineers 8. Governance, Standards & Operations Network standards & best practices Change management & ITIL awareness, Lifecycle management (design → build → operate → retire), Cost optimization (CapEx vs OpEx), SLA & availability modeling.
