Core Responsibilities

Primary Functions

Develop and execute comprehensive network infrastructure plans, encompassing routing, switching, wireless, and data center architectures to support current and future business requirements.
Conduct in-depth capacity planning and performance analysis of the network, forecasting future needs and identifying potential bottlenecks before they impact service quality.
Design and architect scalable, resilient, and secure network solutions for LAN, WAN, SD-WAN, and cloud environments, ensuring high availability and optimal performance.
Create detailed network diagrams, implementation plans, and configuration templates for new network deployments and significant modifications to existing infrastructure.
Evaluate, recommend, and rigorously test new networking hardware, software, and emerging technologies to continuously enhance network capabilities and drive innovation.
Collaborate effectively with cross-functional teams, including systems administrators, security specialists, and application developers, to ensure network designs align with their technical requirements.
Lead network planning projects from conception through to completion, defining project scope, timelines, and resource allocation while managing stakeholder expectations.
Perform regular network assessments and audits to ensure strict compliance with industry standards, corporate security policies, and internal best practices.
Develop and maintain comprehensive, up-to-date documentation for all network designs, standards, configurations, and critical operational procedures.
Model and simulate network traffic patterns and potential failure scenarios using specialized software (e.g., OPNET, GNS3, EVE-NG) to validate design resilience and performance under stress.
Analyze and translate complex business requirements into tangible technical network specifications, ensuring all solutions are cost-effective and meet strategic objectives.
Plan and oversee the seamless integration of network services for corporate mergers, acquisitions, and new site deployments, ensuring uninterrupted connectivity and service transition.
Develop detailed cost analysis models and budget forecasts for network projects, accounting for hardware, software, licensing, and ongoing operational expenses.
Define, document, and maintain enterprise-wide network addressing schemes, including IPAM (IP Address Management), VLAN segmentation, and routing policies.
Proactively research and stay current with evolving industry trends, protocols (e.g., BGP, OSPF, MPLS, Segment Routing), and vendor-specific technologies to inform strategic planning.
Serve as the subject matter expert and a top-tier escalation point for complex network issues that require in-depth analysis and design-level troubleshooting.
Manage relationships with telecommunications carriers and technology vendors, evaluating service level agreements (SLAs) and participating in contract negotiations.
Develop and implement network automation strategies using scripting languages (e.g., Python, Ansible) to streamline provisioning, configuration, and monitoring tasks.
Plan, coordinate, and communicate network maintenance windows and system upgrades to minimize disruption to critical business operations.
Create and present detailed technical proposals and compelling business cases to senior management and other key stakeholders to justify significant network investments.
Develop robust network security plans in close collaboration with the cybersecurity team, integrating firewalls, IDS/IPS, and access control policies directly into the network architecture.
Oversee the complete lifecycle management of all network hardware and software, strategically planning for technology refreshes and end-of-life replacements.

Secondary Functions

Mentor and provide technical guidance to junior members of the network engineering and operations teams.
Participate in the development and refinement of the organization's IT disaster recovery and business continuity plans.
Assist in the financial planning process by providing input for the annual IT infrastructure budget.
Liaise with the project management office (PMO) to ensure network-related tasks are accurately tracked and reported within larger corporate initiatives.
