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 reliability hardening over time, i
