Core Responsibilities

Primary Functions

Lead end-to-end network implementation projects: develop detailed implementation plans, cutover strategies, rollback plans, acceptance criteria, and runbooks to deploy campus, data center, and WAN solutions that meet business availability, latency, and security targets.
Architect and design complex multi-vendor network solutions (Cisco, Juniper, Arista, Palo Alto, Fortinet, Huawei) including routing/switching, EVPN-VXLAN data center fabrics, MPLS, DMVPN, and large-scale BGP environments to support application SLAs.
Define solution blueprints and network reference architectures for hybrid and multi-cloud connectivity (AWS Direct Connect, Azure ExpressRoute, GCP Interconnect), ensuring secure, high-throughput, and low-latency connections.
Build detailed logical, physical, and protocol-level designs (IP addressing, VLANs, VRFs, route-reflection, BGP policy, route-maps, ACLs) and produce implementation-ready configuration templates and standardized design patterns.
Own migration strategy and phased cutover plans for technology refreshes, data center relocations, WAN transformations, or SD-WAN rollouts; coordinate pilot, validation, and staged production migration to minimize business disruption.
Lead network automation and orchestration initiatives: design and implement Ansible playbooks, Python scripts, NetConf/REST APIs, and IaC with Terraform to automate provisioning, configuration drift detection, and day-2 operations.
Design and validate security and segmentation models (micro-segmentation, firewall insertion, NAC integration), ensure compliance with corporate security controls, and collaborate with security architects on secure-by-design implementations.
Define capacity planning, performance baselining, and scalability strategies; analyze traffic patterns, growth forecasts, and QoS policy requirements to right-size infrastructure and avoid saturation.
Create and execute comprehensive test plans (functional, interoperability, failover, performance, security testing) in lab and pre-production environments; lead test validation and document results against acceptance criteria.
Produce and maintain high-quality documentation: network diagrams, configuration standards, runbooks, change requests, test reports, and knowledge transfer materials for operations and NOC teams.
Manage vendor and partner relationships during procurement, implementation, and support phases; evaluate vendor solutions, negotiate deliverables, and drive vendor performance against SLAs.
Serve as the technical lead for cross-functional implementation teams (project managers, systems, security, storage, cloud, and application owners); facilitate design reviews, status meetings, and decision tracking.
Implement observability and monitoring frameworks: select and configure network telemetry, SNMP, sFlow, NetFlow/IPFIX, streaming telemetry, and integration with APM and NMS tools for proactive fault detection.
Ensure change control and governance: author RFCs, coordinate CAB schedules, run capacity and risk assessments, and oversee post-change validation and remediation steps.
Drive cost optimization and total cost of ownership (TCO) analysis for WAN and cloud networking solutions, recommending trade-offs between capex, opex, and performance.
Provide hands-on configuration and troubleshooting for complex incidents during implementation windows; lead root cause analysis and define corrective actions to prevent recurrence.
Champion standardization: create reusable configuration templates, naming conventions, and operational runbooks to reduce variability and accelerate future deployments.
Implement QoS designs to prioritize critical application traffic across WAN and data center interconnects; validate behavior under congestion and failover conditions.
Prepare and deliver executive and technical presentations: implementation status, risks and mitigations, architecture decisions, and post-implementation review findings.
Mentor and train network engineers and operations staff on new technologies, architectures, and automated workflows; establish a knowledge transfer plan for sustained operations.
Design disaster recovery and business continuity networking strategies: ensure redundancy, multi-path routing, automated failover, and documented recovery procedures for critical sites and services.
Ensure regulatory and compliance alignment (PCI, HIPAA, GDPR where applicable) for network architectures that handle sensitive or regulated traffic, coordinating with compliance teams.
Evaluate and pilot new technologies (SDN controllers, network telemetry platforms, intent-based networking, 5G private networks) and recommend adoption roadmaps based on business value and maturity.
Collaborate with cloud and application teams to design secure, low-latency connectivity patterns (microservices East-West traffic, VPC/VNet peering, transit gateways) that optimize cost and performance.
Coordinate handover to operations: define support models, escalation matrices, runbook walkthroughs, and ensure successful transition to NOC/SRE teams with measurable service level agreements.

Secondary Functions

Support incident post-mortems and continuous improvement initiatives; feed lessons learned into architecture standards and automation playbooks.
Participate in procurement activities by preparing technical evaluations, proof-of-concept criteria, and scoring vendor solutions against architecture requirements.
Assist pre-sales and solutioning teams with technical scoping, estimates, and risk identification for network-related offerings.
Maintain professional certifications and continuous learning to stay current with evolving networking technologies and best practices.
