Responsibilities

• Lead the design, operation, and end-to-end platform experience of mission-critical distributed data services (such as Kafka, Redis, and others) running at massive scale across Kubernetes clusters (EKS, GKE) and multi-cloud environments.
• Manage the data & caching infrastructure supporting Petabytes/day ingestion, ensuring low-latency, high-throughput, cost-effective operation at global scale.
• Consolidate and optimize multi-tenant Kafka clusters to reduce cost, improve resilience, and streamline operations.
• Build highly automated, self-service infrastructure to enable complete cloud portability across AWS, GCP, and air-gapped on-prem environments.
• Drive lifecycle automation for owned distributed data services using GitOps principles and tools (GitHub Actions, ArgoCD, Terraform), reducing operational toil and minimizing pager fatigue.
• Define and implement standards for observability, high availability (HA), backup, and disaster recovery (DR) of workloads in Kubernetes.
• Partner with FinOps and engineering stakeholders to continuously optimize performance, cost, and operational overhead across data platform components.

Requirements

• Exposure to multi-cloud environments and strong expertise in at least one major cloud provider (AWS, GCP, or Azure).
• Experience with Infrastructure as Code (IaC) and GitOps practices and tools (Terraform, ArgoCD, etc.).
• Solid understanding of CI/CD pipelines and workflow automation (GitHub Actions, Argo Workflows, etc.).
• Familiarity with advanced deployment strategies (blue-green, canary, rolling).
• Strong scripting or development skills (e.g., Python, Go, or similar).
• Nice to have (or learn on the job): experience with self-hosted Kafka and/or Redis running in Kubernetes (performance tuning, scaling, partitioning, persistence, operator-based lifecycle management); experience with other messaging systems or data stores (e.g., Cassandra, ClickHouse); experience providing Database- or Messaging-as-a-Service (DBaaS/PaaS) for internal teams or customers.
