Senior Site Reliability Engineer (Azure)

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, and Application Insights.
• 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, including IAM reviews, backup restore drills, and DR exercises
• Collaborate daily with a US-based team during overlapping hours

WHAT WE ARE LOOKING FOR

• Required 7+ years in SRE, DevOps, or cloud infrastructure roles, including direct ownership of production systems under an on-call rotation
• Deep, hands-on Azure experience. AWS-primary backgrounds with light Azure exposure will not be a fit
• Hands-on Azure SQL DBA experience: indexing, query tuning, HA/DR (failover groups, geo-replication), and backup/restore. This is not a generalist SRE role; real database ownership is expected
• Comfort reading query execution plans and diagnosing performance regressions at the database level, not just infrastructure monitoring
• Terraform or equivalent IaC in production
• Experience with observability tooling: Application Insights, Azure Monitor, Datadog, or similar
• Strong written and spoken English; daily communication with a US team and occasional client stakeholders
• Work schedule overlapping US Eastern hours (roughly 9 to 5 Eastern is ideal)
• Nice to HaveExperience in HIPAA, PHI, or other regulated environments. A background check to healthcare-industry standards is required prior to production access
• Cosmos DB RU optimization and partition key design at high throughput
• Kubernetes experience
• Prior work in a multi-tenant SaaS environment

ON-CALL EXPECTATIONS

This role includes a pager-based on-call rotation covering SEV-1 and SEV-2 incidents, shared with the rest of the SRE team. On-call is a core part of the role. Expect it to be light at first and ramp as the team takes over production responsibility.

COMPLIANCE AND ACCESS

• All personnel are named and approved by the client before any access is provisioned
• Background checks to healthcare-industry standards are completed prior to production access
• Production access is provisioned through the client identity provider with MFA and time-bound elevation

BENEFITS

• Full-time employment
• Paid time off
• Supplemental health insurance
• Learning credits for training and certification
• Performance incentives
• Regular one on ones and ongoing career support
• Fully remote

WHY THIS ROLE

• You are building the observability, on-call, and deployment practices, not inheriting someone else's
• Small senior team, direct access to senior engineers, no layers of process
• Interesting scale problems: multi-tenant data at volume and real performance challenges, in an environment that has to stay up while you harden it
