Senior Site Reliability Engineer (Azure)

Location: Remote, LATAM

Job Type: Full-Time, with benefits

OpsGenius is a boutique US-based cloud operations firm. We take over the operational side of large production platforms so engineering teams can get back to building.

We are hiring a Senior SRE to join a small, senior team standing up the operational foundation for a large multi-tenant SaaS platform on Azure, running at significant scale across many environments and a high-volume API surface.

The platform has scaled quickly, and you will be one of the people building the operational foundation alongside it: observability, on-call, and deployment practices. This is hands-on production ownership, not a ticket queue.

WHAT YOU WILL DO
- Build out observability: SLO definitions, alert rationalization, synthetic checks, and dashboards using Azure Monitor, Application Insights, and potentially Datadog
- Stand up and participate in an on-call rotation, including paging tooling, escalation paths, and incident documentation
- Modernize deployments:



blue/green or canary patterns with validated rollback, automated smoke tests, and Infrastructure as Code with Terraform
- Perform Azure SQL performance work: query optimization, indexing strategy, and execution plan analysis across a large multi-tenant estate
- Own backup and restore strategy for Azure SQL, including point-in-time recovery testing and periodic restore drills
- Tune elastic pool sizing and evaluate DTU versus vCore tradeoffs for cost and performance
- Optimize Cosmos DB RU consumption and partition key design for high-throughput workloads
- Operate containerized workloads on Azure Container Apps, alongside App Service and Service Bus
- Write operational runbooks (incident triage, rollback, backup restore, secret rotation, certificate renewal) that any on-call engineer can follow
- Contribute to Azure cost optimization: right-sizing, autoscaling tuning, tagging, and cost reporting
- Support security and reliabili
