  • Own substantial parts of Buildkite’s AWS and multi-cluster Kubernetes platform from design through production operation.
  • Design reusable, self-service automation for provisioning and operating secure, consistent, and isolated platform environments.
  • Deliver regional architecture, request routing, disaster recovery, and tested failover capabilities.
  • Improve Kubernetes networking, upgrades, patching, scaling, observability, capacity management, and recovery.
  • Make infrastructure and deployments safer through secure defaults, progressive delivery, automated guardrails, clear health signals, and fast rollback.
  • Partner with product teams to diagnose distributed-system problems across service, datastore, network, and platform boundaries.
  • Turn incidents, capacity limits, and operational signals into durable engineering improvements.
  • Write well-tested, observable, documented, and operable systems; lead design discussions, review code, share context, and mentor other engineers.

  • Developer experience: Experience building CI/CD, internal-platform, or self-service capabilities that make the safe path easier for other engineers.
  • Experience owning production systems through growth, failures, migrations, and incidents.
  • Production AWS, Kubernetes, and infrastructure-as-code experience.
