- Perform packet-level and protocol-level analysis to identify root causes of performance, availability, and connectivity issues.
- Lead or participate in network infrastructure projects such as office openings, site relocations, hardware refreshes, network migrations, circuit upgrades, and technology deployments.
- Coordinate circuit installations, upgrades, cross-connects, handoffs, testing, migrations, terminations, and outage remediation with carriers, local exchange carriers, and data-center providers.
- Develop implementation plans, test plans, rollback procedures, validation steps, and supporting documentation for network changes.
- Maintain accurate logical and physical network diagrams, IP address documentation, circuit inventories, configuration standards, and operational procedures.
- Monitor network availability, capacity, performance, and configuration compliance using SolarWinds Orion or similar network-management platforms.
- Review monitoring alerts and performance trends to identify recurring issues, capacity constraints, and opportunities for proactive improvement.
- Ensure network-device configurations are backed up, standardized, and maintained in accordance with organizational security and operational requirements.
- Perform root-cause analysis for significant incidents and recommend corrective and preventative actions.
- Provide technical guidance to service desk, infrastructure, security, application, and site-support teams for network-related issues.
