• Support detection and incident response by maintaining telemetry availability, retention and quality.
• Monitor platform health, capacity and performance, resolving bottlenecks and scalability issues.
• Maintain documentation, SOPs, data flow mappings and drive continuous improvement for cost, performance and detection coverage.
