• Implement progressive delivery strategies such as blue/green and canary deployments.
• Advance Infrastructure as Code with Terraform, Helm, and Argo CD, defining reusable patterns for the org.
• Operate and optimize streaming and analytics infrastructure: Kafka, Flink, and ClickHouse.
• Build automated testing into the CI/CD lifecycle.
• Improve system observability — define SLOs, alerts, and dashboards.

• Mentor engineers across teams on Kubernetes, CI/CD, and cloud infrastructure.

Required Qualifications:

• 6+ years in SRE, DevOps, or Infrastructure roles, with significant production Kubernetes experience.
• Hands-on experience integrating AI/LLM tooling into engineering or operational workflows (e.g., MCP servers, AI agents acting on infrastructure), and a clear grasp of the security and governance considerations of giving AI access to production.
• Proven success building CI/CD pipelines (GitHub Actions, Jenkins, GitLab CI, or similar).
• Strong with Kubernetes internals and managed services like EKS, GKE, or AKS.
• Expertise with Infrastructure as Code (Terraform, Helm, Pulumi) and GitOps.
• Proficient in Python, Bash, or Go.
• Knowledge of observability tooling (Prometheus, Grafana, Datadog, OpenTelemetry).
• Production experience with Kafka, Flink, and ClickHouse.
• Strong communication and cross-team collaboration skills.

Preferred Qualifications:

• Multi-region or multi-cluster Kubernetes experience.
• Chaos engineering or resilience testing.
