Responsibilities

  • Operate EKS clusters across multiple environments using Karpenter, Cilium, and ArgoCD-driven deployments.

  • Maintain and evolve Terraform/Terragrunt infrastructure modules, state management, and plan/apply automation.
  • Improve tooling for deployments, schema changes, backups, restores, and incident response.
  • Identify recurring operational pain points and eliminate them through code and self-healing automation.
  • Optimize cloud spending and participate in on-call and incident response.
  • Build platform patterns and tooling that allow large-scale systems to grow without proportionally increasing human operational effort.

Requirements

  • Solid understanding of Linux systems, including disk, memory, networking, and failure modes.
  • Experience supporting stateful systems such as databases, queues, or storage systems.
  • Ability to diagnose and reason about production performance and reliability issues.
  • Comfort owning systems end-to-end, including on-call responsibilities.
  • Nice to have: experience with ArgoCD GitOps workflows, GitHub Actions pipelines, multi-region infrastructure, or AI agent-enabled infrastructure services.

Benefits

  • Fully remote work for candidates in the US Central or Eastern time zones.
  • Async-first work culture with Tuesdays and Thursdays free of meetings.
