• Implement and manage cloud-native systems (AWS) using best-in-class tools and automation.
• Operate and enhance Kubernetes clusters, deployment pipelines, and service meshes to support rapid delivery cycles.
• Design, build, and maintain the infrastructure powering our multi-tenant SaaS platform with reliability, security, and scalability in mind.

• Build internal platform tools and automation to support provisioning, monitoring, and operational efficiency.
• Monitor infrastructure and applications ensuring high-quality user experiences.
• Participate in a shared on-call rotation, responding to incidents, troubleshooting outages, and driving timely resolution and communication.
• Act as an Incident Commander during the on-call duty and coordinate cross-team responses effectively to maintain an SLA.
• Drive and refine incident response processes, reducing Mean Time to Detect (MTTD) and Mean Time to Recovery (MTTR).
• Diagnose and resolve complex issues independently, minimizing the need for external escalation.
• Work closely with software engineers to embed observability, fault tolerance, and reliability principles into service design.
• Automate runbooks, health checks, and alerting to support reliable operations with minimal manual intervention.
• Support automated testing, canary deployments, and rollback strategies to ensure safe, fast, and reliable releases.
