About the role
Testlify runs a multi-tenant talent assessment platform serving customers across four AWS regions (US, EU, Australia, Middle East). Every region carries its own EKS cluster, its own data plane, and its own data- residency obligations. That means the platform is not one workplace you can hold in your head — it is four, kept in step by Terraform and GitOps.

You will own that platform end to end: the Terraform that provisions it, the ArgoCD repos that deploy into it, the observability that tells us when it is unhealthy, and the on-call response when it is not. This is a hands-on infrastructure role, not a ticket-queue role. You will be trusted with production and expected to leave it more boring than you found it.

What you will actually work on
Multi-region Kubernetes. Four production EKS clusters plus staging, node lifecycle on Karpenter,
autoscaling via KEDA and metrics-server, ingress through nginx-ingress and the AWS Load Balancer
Controller.

GitOps as the single source of truth. All cluster state lives in a Git repo rendered by ArgoCD per region.



Live kubectl changes get reverted by self-heal, by design. You will keep that invariant honest and make sure deletions cascade properly.

Terraform at scale. ~30 in-house modules (VPC, EKS, RDS, DocumentDB, ECS, OpenReplay, Metabase, OTel collectors, Vercel projects) composed into per-region live stacks and executed through Terraform Cloud. You will keep drift near zero and treat unapplied branches as a defect, not a state.

Secrets and identity. External Secrets Operator against AWS Secrets Manager, IRSA and OIDC federation for passwordless access to MongoDB Atlas and AWS APIs, plus scheduled credential rotation. Getting trust policies and per-environment overrides exactly right is a large part of the job.

Observability. A regional OpenTelemetry collector fleet relaying into Grafana Cloud, self-hosted
OpenReplay for session replay, and Metabase on EKS + RDS for analytics. You will improve signal,
not
