• Build dashboards and telemetry using:
• Grafana
• ELK Stack
• CloudWatch
• Splunk (preferred)
• Improve application and infrastructure observability using logs, metrics, and distributed tracing.

Incident Response & Reliability Engineering

• Participate in 24x7 on-call rotations.
• Lead production incident response and service restoration.
• Drive post-incident reviews and continuous improvement initiatives.
• Reduce Mean Time to Detect (MTTD) and Mean Time to Recover (MTTR).
• Manage cloud infrastructure across:
• AWS
• Support hybrid environments including:
• VMware
• Nutanix
• Deploy and manage highly available infrastructure services.
• Deploy and manage Kubernetes clusters.
• Support:
