• Lead architectural reviews for new services and ensure reliability non-functionals (availability targets, RTO/RPO) are embedded from design through to production.
• Champion and implement chaos engineering practices using Azure Chaos Studio and custom fault injection frameworks to proactively surface reliability risks.
• Drive Disaster Recovery (DR) design and conduct quarterly DR drills across Azure paired regions. Incident Management & On-Call
• Serve as Incident Commander for P1/P2 major incidents, own end-to-end incident lifecycle from detection through resolution and Post-Incident Review (PIR).
• Participate in a structured On-Call rotation with follow-the-sun global coverage; maintain response SLAs of <5 minutes for Tier-0 services.
• Drive blameless post-mortem culture and ensure all action items from PIRs are tracked and delivered within agreed SLA.

Observability & Platform Engineering

• Design and operate the enterprise observability stack: Azure Monitor, Log Analytics Workspaces, Application Insights, and Azure Managed Grafana; ensure full MELT (Metrics, Events, Logs, Traces) coverage.
• Build and maintain alerting frameworks using Azure Monitor Alert Rules and Azure Action Groups integrated with PagerDuty and ServiceNow.
• Develop and operate platform automation, runbooks, and self-healing capabilities using Azure Automation, Logic Apps, and Python/PowerShell scripting.

CI/CD & Infrastructure Reliability

• Collaborate with DevOps and development teams to embed reliability gates into Azure DevOps pipelines ; automated performance testing, synthetic monitoring, and progressive deployment (canary/blue-green) strategies.
• Manage reliability of AKS clusters across multiple Azure regions, own node pool scaling, upgrade strategy and cluster hardening in alignment with CIS Benchmarks.
• Contribute to infrastructure-as-code reliability reviews using Terraform/Bicep to enforce standards across Azure Landing Zones.
