This is a senior, hands-on role in a production environment where minutes of downtime translate directly into customer impact. You’ll take ownership of key parts of our platform, driving technical direction and making pragmatic trade-offs between reliability, cost, and developer experience. We build with self-service in mind, creating paved roads, abstractions, and guardrails that enable product teams to move fast without needing to understand the underlying complexity.## Your responsibilities will include* Design and manage core AWS infrastructure via Terraform and Terragrunt* Build and operate robust Kubernetes, GitOps and observability tooling* Shape how engineering teams ship to production, progressive rollouts, canary deploys and fast, safe rollbacks* Bake security into the SDLC, policy-as-code, OIDC-based cloud access, secret scanning and pre-merge controls, working closely with our Security team* Partner with engineering teams on infrastructure, database and deployment best practices* Provide and continuously improve CI/CD and developer tooling* Share an on-call rotation with the team, supported by the observability and tooling you help build* We make use of AI-assisted tooling (e.g. code generation, debugging, and platform operations). You’re either already comfortable working this way, or excited to adopt it.## Your experience* Production experience running Kubernetes at scale, not just deploying to it, but operating it.* Proven ability to improve developer experience and platform adoption across teams* Deep cloud experience, ideally on AWS.* Strong infrastructure-as-code skills with Terraform (Terragrunt a bonus).* Hands-on experience with a modern observability stack including Datadog, Prometheus, Grafana.* Modern CI/CD experience: GitHub Actions, ArgoCD, Flux.* Comfort scripting in at least one of the following: TypeScript/Node, Python or Go.* A solid grounding in Linux, networking, and security fundamentals.We don’t expect every box to be ticked.
