Roles & Responsibilities

Reliability & Availability Engineering

- Define, own, and enforce enterprise-wide SLOs, SLIs, and Error Budgets across all Tier-0 and Tier-1 Azure-hosted services; report SLA compliance to executive stakeholders monthly.
- 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

- 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.
