Roles & 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 & Compli ance
- 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.
