• Define, implement, and refine SLOs/SLIs and operational health indicators for business-critical services.
• Automate infrastructure provisioning and application deployment workflows using Terraform, GitHub Actions, and ArgoCD.
• Drive observability and telemetry adoption using Datadog, including dashboards, alerts, custom metrics, and distributed tracing.
• Act as incident commander during critical production issues; conduct blameless postmortems and guide root cause remediation.
• Lead cross-team efforts in reducing mean time to detect (MTTD) and resolve (MTTR), and promoting self-healing systems.
• Partner with security and compliance teams to ensure that systems are secure, auditable, and operationally compliant.
• Enhance service resiliency through strategies including Kafka-based event-driven architecture, retries, rate limiting, and circuit breakers.

• 8+ years of experience in Site Reliability Engineering, DevOps, or Platform Engineering roles in large-scale production environments.
• Expertise in building and maintaining Java-based microservices using Spring Boot, Tomcat, and Redis in containerized deployments.
• Strong hands-on experience with Kubernetes, AKS, and ArgoCD for orchestration and GitOps deployment workflows.
• Proficiency in Python, Java, Bash, or Go for automation, scripting, and infrastructure tooling.
• Proven ability to implement observability platforms and practices using Datadog (metrics, logs, traces, dashboards, alerts).
• Advanced experience working with CI/CD pipelines using GitHub and GitHub Actions.
• Deep understanding of networking, Linux (especially Ubuntu), distributed systems, and container security.
• Experience operating message-driven architectures using Kafka, with an emphasis on throughput, retries, and resilience.
