• Implements and refines post-incident validation methods, integrating break-fix outcomes and lessons learned into continuous test improvements.

• Reviews and approves L1 and L2 network changes, and presents high-impact changes to cross-team change management boards, ensuring risks are understood and mitigated.

• Partners with cross-functional teams to drive pre-production validation efforts, ensuring systems and environments meet compliance and deployment-readiness criteria.

• Prepares and delivers audit documentation and test evidence to support internal Governance, Risk, and Compliance (GRC) processes, maintaining alignment with security and policy requirements.

Monitoring and Reliability:

• Works with others (e.g. monitoring teams) to customize dashboards, telemetry pipelines, and alerting systems, defining service level objectives (SLOs) based thresholds and metrics to monitor network health.

• Partners with monitoring and Site Reliability Engineering (SRE) teams to refine alerting systems and enhance early detection of network anomalies and degradation.

• Leads incident response during support rotations, driving root cause analysis and coordinating cross-team resolution for escalated issues.

• Builds and improves internal tools that enable frontline support teams to efficiently respond to network failures and recurring operational issues.

Cross-Team Collaboration and Leadership:

• Drives test and deployment milestones in collaboration with project/program managers, adapting plans to address risks and ensure cross-team alignment.

• Mentors junior engineers and acts as a technical SME, providing hands-on guidance in resolving complex issues.

• Leads customer engagements on technical escalations and delivers clear, actionable root cause analysis (RCA) documentation.

• Influences team-level roadmap and architecture decisions, contributing solutions that align with broader engineering goals.

• Coordinates with vendors and internal teams to resolve standards misalignment, ensuring integration meets technical and operational expectations.

Performance and Capacity Management:

• Leads analysis of network performance metrics (e.g., latency, throughput, packet loss) to identify systemic inefficiencies and drive scalable improvements.

• Forecasts infrastructure needs using performance and capacity data, ensuring systems are prepared for anticipated traffic and service growth.

Planning & Execution:

• Manages and coordinates moderately complex tasks, monitoring timelines and deliverables to ensure timely completion and adherence to requirements for a moderately-sized project or initiative.
