Perform root cause analysis for recurring or high-impact network incidents and implement permanent corrective actions to reduce repeat issues.
Program Development and Implementation – Plan, test, and deploy network changes, upgrades, patches, firmware updates, configuration changes, and security improvements in alignment with approved change management processes. Prepare technical input for change requests, including impact assessments, implementation plans, back-out plans, validation steps, and post-implementation review. Monitor network availability, performance, capacity, and security using approved tools; identify trends, risks, and opportunities for proactive improvement.
Reporting and Documentation – Maintain accurate network documentation, diagrams, configuration baselines, inventory records, procedures, knowledge articles, and support artifacts for troubleshooting and audit readiness.
Team Leadership and Vendor Management – Mentor and provide technical guidance to Tier 1 and Tier 2 staff; contribute to standards, escalation procedures, and improved ticket handling for network-related issues. Engage and manage vendor escalations by collecting evidence, reviewing logs, coordinating repairs or replacements, and validating service restoration.
Perform other related duties as assigned by management.
