What You'll Do

• Define and own service level objectives across Sintra's core platform services, and use error budgets to balance reliability investment against feature velocity.
• Build and maintain production observability - metrics, logging, distributed tracing - so failures are visible, debuggable, and actionable before users report them.
• Lead incident response: on-call rotation, structured postmortems, and systematic follow-through that actually closes the loop.
• Own the CI/CD pipeline and deployment process - safe rollouts, canary deployments, automated rollback, and release health checks.
• Automate toil: identify manual operational work and replace it with reliable, well-tested systems.
• Partner with product engineers to embed reliability requirements - SLOs, failure modes, graceful degradation - into new features from the design stage.
• Maintain runbooks, incident playbooks, and operational documentation to a standard that lets any engineer handle an alert at 3am.
• Capacity plan for growth: model traffic, identify bottlenecks, and scale infrastructure ahead of demand.

Who We're Looking For

• 4+ years in SRE, DevOps, or infrastructure engineering in a production environment
• Hands-on experience with AWS and container orchestration (Kubernetes, ECS, or equivalent) at scale.
• Infrastructure as code fluency - Terraform, Pulumi, or similar - treating infrastructure changes like software changes.
• Strong observability skills: you know how to instrument a service, build useful dashboards, and write alerts that fire when they should and stay quiet when they shouldn't.
• Experience owning incident response end-to-end: response, coordination, postmortem, and follow-up.
• Comfortable writing automation in Python, Go, or Bash; you reach for code before clicking through a UI.
• Solid understanding of distributed systems and how they fail - networking, storage, queuing, service dependencies.
• Clear communicator who can translate system behavior into plain language for product and engineering peers.
