Your Role You will independently execute defined infrastructure work that keeps Polygon's production systems reliable, secure, and operationally efficient. This role is hands-on and operational, with a focus on cloud infrastructure, Kubernetes, infrastructure as code, observability, incident response, and the secure lifecycle of secrets and configuration across services. You will work core hours overlapping with the EU business day and contribute as a trusted infrastructure partner, including reviewing and approving infrastructure changes and supporting production systems through incidents and continuous improvement. Your Responsibilities Operate production Kubernetes environments on GKE, including day-to-day cluster operations, troubleshooting, maintenance, and reliability improvements. Build and maintain infrastructure as code using Pulumi, including Pulumi ESC for environments, secrets, and configuration, primarily in TypeScript and Python. Manage GitOps workflows with ArgoCD and maintain reliable CI/CD pipelines, including diagnosing pipeline-level race conditions. Operate GCP infrastructure across IAM, Pub/Sub, Cloud SQL, VPC, and Secret Manager. Tune Pub/Sub subscriptions through settings such as acknowledgement deadlines, dead-letter queue redrive behavior, and backlog alerting. Manage Cloudflare entirely as code, including Workers and DNS, and maintain lifecycle cleanup for stale preview environments. Own the secrets and configuration lifecycle across services, including provisioning, rotation, naming conventions, and preventing cross-service authentication drift. Respond independently to production incidents through triage, escalation, documentation, runbooks, and incident.io workflows. Review and approve infrastructure pull requests, helping maintain a high standard for safety, correctness, and operational readiness. Build and maintain Grafana dashboards and alerts, with working knowledge of the underlying agent and collector layer, including Grafana Alloy. Execute SOC2-driven infrastructure and security work and maintain appropriate separation between regulated or sensitive-data environments. Read and contribute to systems involving Go, TypeScript, and Python.
