Responsibilities

  • Build and operate the cloud infrastructure and Kubernetes clusters that support our production systems and engineering teams.
  • Design and develop production sandbox management and orchestration services, including APIs and distributed coordination for allocation, isolation, health monitoring, failure recovery, and resource lifecycle management.
  • Improve workload scheduling, autoscaling, and capacity management to support growing and variable demand.
  • Strengthen infrastructure security through workload isolation, access controls, network policies, and secure configuration.
  • Improve performance and cost efficiency by reducing startup latency, increasing resource utilization, and addressing system bottlenecks.
  • Build observability and operational tooling that help engineers understand system behavior and resolve problems quickly.
  • Debug production issues across service code, Kubernetes, Linux, networking, and cloud infrastructure, then implement durable fixes.
  • Improve infrastructure as code, deployment pipelines, and upgrade processes to make changes repeatable and reliable.

Qualifications

  • Experience developing distributed systems, including handling concurrency, retries, partial failures, and resource lifecycle management.
  • Solid understanding of Linux, containers, networking, and cloud security fundamentals.
  • Experience with infrastructure as code, CI/CD, and production observability.
  • Ability to reason about tradeoffs between reliability, security, performance, cost, and operational complexity.
  • Ownership from design and implementation through deployment and ongoing operation.
  • Strong communication skills and the ability to work through ambiguous problems with other engineers.
