Responsibilities

• Assess business, application, security, compliance, and operational requirements; identify practical network solutions; and prepare recommendations supported by feasibility, risk, cost, benefit, CapEx, OpEx, lifecycle, and supportability analysis.
• Develop and execute design-to-deployment plans that meet scope, schedule, cost, quality, resiliency, change-control, implementation sequencing, rollback, compliance, and operational-readiness requirements.
• Assess, mitigate, troubleshoot, and resolve complex network issues using industry-standard tools and methods, including packet analysis, flow analysis, telemetry, configuration-drift reporting, monitoring dashboards, fault-domain isolation, RCA practices, and NetScout.
• Develop processes, standards, diagrams, and documentation that support design execution, operational readiness, troubleshooting, and knowledge transfer.
• Provide technical leadership for network design and delivery by guiding engineering decisions, coordinating implementation teams, resolving technical blockers, validating design assumptions, and ensuring solutions aligning with enterprise architecture, information security, audit, regulatory compliance, service reliability, vendor governance, and business objectives.
• Build strong partnerships across the organization and with vendor partners, collaborating with peers, leaders, managed services providers, IT Security, Technology Risk, and cross-functional stakeholders to drive alignment and execution.
• Mentor team members, build technical capability, foster a collaborative team environment, and communicate clearly through strong listening, writing, and verbal communication skills.
• Champion innovation lead change, and support continuous improvement across network design, delivery, operations, managed services, capacity planning, resiliency, service reliability, vendor performance, cost optimization, and operational controls.
• Manage multiple large, complex, and concurrent projects while applying agile delivery practices, project management fundamentals, attention to detail, research skills, and strong execution discipline.
• Lead small to mid-size technical delivery teams through design reviews, implementation planning, peer reviews, change preparation, testing, cutover coordination, operational acceptance, and post-implementation validation.
