Responsibilities

• Define and own reliability goals for network services and critical paths, including SLIs, SLOs, availability targets, and error budgets where appropriate.
• Drive reliability improvements across the network, including services, site readiness, inter-site connectivity, data center interconnectivity, and operational standards.
• Own incident response for assigned areas, lead investigations and postmortems, and turn failures into durable fixes.
• Build and evolve observability through actionable metrics, logs, traces, alerting, and faster debugging workflows.
• Design safer change workflows using automation, CI/CD, test and staging environments, canarying, rollbacks, and auditability for network changes.
• Collaborate with network engineers and platform teams to embed operability into designs and keep operations practical and efficient.

Requirements
