Platform Engineer II, Foundation

About the role

The Platform Engineering team at Chainalysis provides the shared infrastructure, tooling, and developer experience layer that powers every engineering team. We are moving away from team-owned infrastructure silos and consolidating onto shared, scalable platform patterns.

Responsibilities

• Build and maintain cloud infrastructure across AWS and GCP using Terraform — designing the modules and patterns that provision the substrate our services run on, and thinking beyond the immediate use case to how your work is consumed across the organization
• Operate and evolve multi-tenant Kubernetes clusters (EKS) serving the entire engineering organization — owning node lifecycle, upgrades, security contexts, and networking decisions that affect every team
• Own the operational side of our streaming infrastructure migration from managed Kafka (MSK) to WarpStream, building and maintaining the tooling that supports it
• Contribute to platform tooling and reconcilers that underpin our platform contract model — writing Go, working with the Kubernetes API, and building high-quality self-service primitives that engineering teams rely on to declare what their services need
• Design and maintain foundational networking and security infrastructure — transit gateways, GCP interconnect, ingress, security groups, IAM policies, and IRSA — getting the invisible plumbing right so nobody has to think about it
• Participate in on-call rotations and drive operational excellence — responding to infrastructure incidents, writing and improving runbooks, and feeding every incident pattern back into AI automation so the same class of issue never repeats

Requirements

• 3+ years of platform engineering experience
• Hands-on experience with AWS services (EC2, EKS, IAM, S3, VPC, or similar) — we're looking for people who have built and operated real infrastructure, not certifications
• Working knowledge of Kubernetes in production — you have operated or deployed workloads on K8s clusters beyond a local environment
• Experience with infrastructure-as-code (Terraform strongly preferred; Pulumi or CloudFormation acceptable)
• Proficiency in at least one of Go, Python, or shell scripting — Go is preferred because our reconciler work is in Go, but you should be ready to turn your hand to whatever the problem demands
• Comfort with CI/CD pipelines (GitHub Actions, Argo, Jenkins, or similar) and hands-on experience with on-call and incident response — you understand what it means to be accountable for production systems

Qualifications

• Experience building Kubernetes operators or controllers — CRDs, reconcilers, and the controller-runtime library
• Familiarity with streaming infrastructure (Kafka, WarpStream, or similar event-driven systems) or depth in networking (VPCs, transit gateways, ingress controllers, DNS, load balancing, and security groups)
• Experience in regulated environments (SOC 2, ISO-27001, or similar compliance frameworks) or familiarity with GitOps patterns (ArgoCD, Flux)
• A passion for platform engineering as leverage — you care about making other engineers more productive, and when you see toil, your instinct is to eliminate it

Skills

• Languages: Go, Python, Bash/Shell, HCL (Terraform)
• Cloud: AWS (EC2, EKS, IAM, S3, VPC, Lambda), GCP
• Infrastructure as Code: Terraform
• Kubernetes: EKS, Helm, CRDs, controller-runtime
• Streaming: Kafka, WarpStream (migrating from MSK)
• Networking: Transit Gateway, GCP Interconnect, Ingress Controllers, DNS, Security Groups
• Identity & Security: IAM, IRSA, Secrets Management
• CI/CD: GitHub Actions
• GitOps: ArgoCD, Flux
