We are looking for a Senior Data Platform Engineer to run the PostgreSQL and Apache Kafka platform behind k0rdent-ai — our multi-tenant control plane for enterprise GPU infrastructure. Every cluster provisioned, every GPU‑hour consumed, and every tenant action is recorded on this platform, so it must be reliable, secure, and recoverable.

This is a hands‑on Dev Ops / SRE role for stateful systems. You will deploy and operate PostgreSQL (CloudNative PG) and Kafka (Strimzi) on Kubernetes using operators, Helm, and Git Ops — across cloud and bare‑metal clusters, in a global control plane and multiple regions. You will own automation, upgrades, observability, backups, and disaster recovery, and give product teams self‑service access to databases and topics through code.

• Run PostgreSQL and Kafka on Kubernetes:
  Deploy, upgrade, scale, and operate Cloud
  
  NativePG and Strimzi clusters with Helm charts and operator custom resources, across cloud and bare‑metal Kubernetes.
• Git Ops & Infrastructure as Code:
  Manage everything declaratively with Argo CD (or Flux), Helm, and Terraform; build CI/CD pipelines for database and Kafka changes, schema migrations, and operator upgrades.
• High Availability & Disaster Recovery:
  Design and operate high availability within each region and cross‑region disaster recovery — PostgreSQL replica clusters, backups and point‑in‑time recovery, Kafka Mirror Maker 2 — with defined RPO/RTO targets and regular failover drills.
• Self‑Service Platform:
  Give product teams self‑service provisioning of databases, users, topics, and ACLs through code, with secure defaults and guardrails.
• Observability & Operations:
  Build monitoring and alerting (Prometheus, Grafana, Open Telemetry) for replication lag, backups, consumer lag, and capacity; participate in on‑call and lead incident reviews.
• Security & Multi‑Tenancy:
  Implement TLS/mTLS, secrets management (Vault/Open Bao), network policies, Kafka ACLs, and per‑tenant isolation; integrate database and Kafka access with our identity platform (Keycloak / OIDC).
• Data Movement & CDC:
  Operate the outbox and change‑data‑capture pipelines (Debezium, Kafka Connect) that keep databases and event streams consistent between the global control plane and regions.
• Automation & Tooling:
  Write automation and small services in Go or Python to remove manual work, and partner with application teams on schema standards and performance troubleshooting.

Must Have

• Experience:
  
  8+ years in Dev Ops, SRE, platform, or infrastructure engineering, including 3+ years running stateful systems (databases or message streaming) in production.
• Kubernetes:
  Strong hands‑on Kubernetes operations — Stateful Sets, persistent volumes and storage classes, pod disruption budgets, scheduling and affinity, network policies, and cluster upgrades — on cloud…
