Responsibilities
Essential Duties and Responsibilities:
Architecture & Design
- Define target-state network architectures (LAN/WAN, data center, campus, branch, edge, SD-WAN, SASE, Zero Trust, Wi Fi).
- Produce HLD/LLD (High-/Low-Level Designs), reference architectures, bill of materials, and network diagrams.
- Architect cloud networking across AWS/Azure/GCP (VPC/VNet, transit, private link, routing, DNS, FW, load balancing, service mesh integration).
- Design resiliency and performance: HA, ECMP, QoS, traffic engineering, capacity planning, multi-region patterns.
- Define standards, policies, and patterns (naming, IPAM, routing, segmentation, encryption, observability).
Implementation & Delivery
- Lead proofs-of-concept and pilots for new technologies (SD WAN/SASE/NAC/automation frameworks).
- Guide implementation teams; review configuration templates, change plans, and cutover runbooks.
- Establish automation-first workflows for provisioning, configuration, compliance, and drift remediation.
Security & Compliance
- Embed Zero Trust principles: micro/macro segmentation, identity-aware networking, secure access.
- Partner with Security to integrate NAC, IDS/IPS, FWaaS, DLP, CASB/SSE/SASE, and logging pipelines.
- Ensure compliance with ISO 27001, SOC 2, PCI-DSS, and data residency/regulatory requirements.
Operations & Reliability
- Define SLOs/SLAs, capacity thresholds, and monitoring KPIs (availability, latency, loss, jitter).
- Build observability: NetFlow/IPFIX, SNMP, streaming telemetry, syslog, packet brokers, NPM/APM.
- Drive problem management: root-cause analysis (RCA), post-incident reviews, and prevention plans.
Automation and Network Management:
- Scripting and automation with Python, Ansible, Terraform, or similar tools for network provisioning and configuration management.
- Familiarity with Infrastructure as Code (IaC) principles.
- Integration with network management and monitoring platforms (SolarWinds, NetBrain, Cisco DNA Center).
Governance & Leadership
- Own the network technology roadmap and multi year investment plan (TCO/ROI).
- Lead vendor selection, bake offs, and contract/SKU optimization.
- Mentor engineers, uplift standards, and evangelize best practices across teams.
- Communicate complex topics to both executive and engineering audiences.
