Core Responsibilities

Primary Functions

  • Lead end‑to‑end network architecture and design projects for enterprise customers, producing technical designs, detailed network diagrams, bill of materials, migration plans, and estimated project timelines while ensuring alignment with business objectives and compliance requirements.
  • Assess existing network environments through comprehensive discovery, traffic analysis, configuration review, and risk assessments to identify bottlenecks, single points of failure, security gaps, and opportunities for consolidation or cost optimization.
  • Design and implement routing and switching solutions using protocols such as BGP, OSPF, EIGRP, VLANs, VXLAN, and MPLS to support multi‑site enterprise connectivity and scalable data center fabrics.
  • Plan and execute SD‑WAN evaluations, pilots, and rollouts, including vendor selection support, policy design for traffic steering, QoS mapping, and integration with existing WAN services and security stacks.
  • Architect and deploy robust network security controls including next‑generation firewalls, IDS/IPS, segmentation, VPN design (site‑to‑site and remote access), and centralized policy management to meet regulatory and industry standards such as PCI, HIPAA, and SOC2.
  • Design cloud networking solutions for AWS, Azure, and GCP including VPC/VNet architecture, transit architectures (Transit Gateway, VNet peering), hybrid VPN/Direct Connect/ExpressRoute integration, and cloud security groups and routing automation.
  • Troubleshoot complex, intermittent network incidents across WAN, LAN, and data center environments using packet capture, flow analysis (NetFlow/sFlow), latency and jitter investigation, and root cause analysis to restore service and prevent recurrence.
  • Develop and implement network performance optimization strategies—capacity planning, QoS, traffic engineering, load balancing, and caching—to deliver measurable improvements in application response times and resiliency.
  • Create and maintain detailed network documentation, runbooks, change records, and standard operating procedures that support repeatable deployments, audits, and knowledge transfer to operations teams.
  • Provide technical leadership during network upgrades and migrations, coordinating cross‑functional teams, scheduling cutovers, creating rollback plans, and managing vendor escalations to minimize downtime and business impact.
  • Implement and integrate network monitoring, observability, and alerting platforms (e.g., SolarWinds, Nagios, Prometheus, ThousandEyes) to proactively detect anomalies, track SLAs, and provide actionable telemetry to stakeholders.
  • Lead security hardening efforts for network devices and services, applying best practices for device configuration, patch management, key/certificate lifecycle, and access control to reduce the attack surface.
  • Drive vendor and partner management activities, including RFP/RFI responses, technical evaluation of vendor solutions (Cisco, Juniper, Arista, Palo Alto, Fortinet, VMware), and negotiation of support and licensing agreements.
  • Build and deliver actionable network migration plans (e.g., IPv4 to IPv6, legacy MPLS to SD‑WAN, on‑prem to cloud) with clear timelines, risk assessments, test plans, and cutover verification steps.
  • Provide hands‑on mentoring and knowledge transfer to internal engineering teams and client staff, enabling sustainable operational support post‑engagement through workshops, training sessions, and shadowing.
  • Work with security, compliance, and application teams to define network segmentation, micro‑segmentation, identity integration (RADIUS/AAA), and policy enforcement that protect sensitive data and support zero‑trust principles.
  • Drive automation initiatives using IaC and scripting (Ansible, Python, Terraform) for repeatable configuration management, provisioning, and network lifecycle tasks to reduce manual errors and accelerate delivery.
  • Lead incident response and post‑incident reviews for major network outages, synthesizing timelines, technical findings, corrective actions, and recommendations for long‑term resilience improvements.
  • Collaborate with project managers and stakeholders to prepare technical bids, statements of work (SOWs), and resource estimates, ensuring projects are delivered on scope, budget, and schedule.
  • Evaluate, prototype, and recommend emerging networking technologies (e.g., intent‑based networking, segment routing, 5G private networks, network virtualization) to enhance client capabilities and future‑proof infrastructure.
  • Ensure compliance with enterprise governance, change control, and risk policies while proposing practical mitigations that balance security, performance, and cost across the network estate.
  • Conduct periodic network health reviews and roadmap sessions with clients to align technical refresh cycles, capacity forecasts, and transformation initiatives with business priorities.

Secondary Functions

  • Support ad‑hoc technical advisory sessions, proof‑of‑concepts, and executive briefings that translate complex network concepts into business value and ROI for stakeholders.
  • Assist operations teams in developing runbooks, on‑call support rotations, and escalation matrices to improve mean time to repair (MTTR) and operational maturity.
  • Contribute to cross‑discipline initiatives including cloud migration, application modernization, and security posture improvement by providing network impact assessments and mitigation strategies.
  • Participate in R&D and lab validation of new network devices and software releases, creating test plans, performance baselines, and compatibility matrices to inform production rollouts.
  • Help prepare technical input and artifacts for security audits and compliance assessments, including configuration audits, access logs, and change history relevant to network controls.
