DevOps Engineer

We are looking for a DevOps Engineer to join our infrastructure team and help scale the platform that runs millions of tests every day for our customers. This role is central to Primates' ability to deliver fast, reliable test execution at scale -- you will own the systems that provision ephemeral test environments, manage compute resources across multiple cloud regions, and ensure that our platform maintains the 99.95% uptime SLA that our enterprise customers depend on. Our infrastructure runs on AWS, orchestrated by Kubernetes (EKS) across three regions (us-east-1, us-west-2, eu-west-1). We use Terraform for infrastructure-as-code, ArgoCD for GitOps-based deployment, and Karpenter for intelligent node autoscaling. The platform's unique challenge is its burst workload pattern: test execution demand can spike by 10x within minutes as customers' CI pipelines trigger simultaneously, and our infrastructure needs to scale up instantly and scale down efficiently to manage costs. You will work on improving our deployment pipeline (currently achieving 15-minute deploy times, with a goal of under 5 minutes), enhancing our observability stack (Datadog for metrics, Loki for logs, Tempo for traces), and building the automation that keeps our multi-region infrastructure running smoothly. You will also be responsible for cost optimization -- with cloud infrastructure as our largest expense category, finding ways to deliver the same performance at lower cost has a direct impact on the company's bottom line. Security is a first-class concern in this role. Our customers send their source code and test results through our platform, and we take that trust seriously. You will work with our security team to implement and maintain SOC 2 Type II controls, manage secrets rotation, configure network policies, and ensure that our infrastructure meets the compliance requirements of our enterprise and healthcare customers. This is a fully remote role open to candidates in North American time zones. You will be part of a 4-person infrastructure team that operates with high autonomy and a strong culture of documentation. We believe that well-documented infrastructure is the foundation of reliability, and we invest significant time in maintaining runbooks, architecture decision records, and operational playbooks.
