Job description

Overview

Own our Google Cloud infrastructure: GKE clusters, Cloud SQL, PubSub, Cloud Logging, Cloud Monitoring, and the services that run on top of them.

Lead our logging infrastructure rebuild — moving from a high-cost, high-convenience setup toward a tiered architecture that balances cost and debuggability.

Drive infra cost optimization as an ongoing owned responsibility, not a one-time project.

Manage and improve our CI/CD pipelines (GitHub Actions) and deployment automation.

Own our observability stack: Prometheus, Grafana, alerting, SLOs.

Review our security posture in Google Security Command Center, implement improvements, and own our response to security audits and customer security reviews.

Configure and maintain IAM, GCP Secret Manager, VPC firewall rules, Kubernetes network policies, and namespace isolation across our private GKE cluster.

Design and practice disaster recovery procedures.

Automate away operational toil - if something happens more than twice, it should not happen manually a third time.

Write documentation and playbooks; we prefer collaborative problem-solving over working in silos.

Requirements

• 5+ years of experience as an infrastructure, platform, or DevOps engineer in a production environment
• Solid experience building and maintaining CI/CD pipelines (GitHub Actions or equivalent)
• Strong working knowledge of Kubernetes and container orchestration
• Experience with infrastructure-as-code, preferably Terraform
• Proficiency in Python and Bash for automation and scripting
• Hands-on experience with GCP or a comparable cloud platform
• Experience with monitoring and observability tools (Prometheus, Grafana or equivalent)
• Cloud security fundamentals: IAM, least-privilege access, GCP Secret Manager, audit logging, network controls, private cluster configuration
• Strong written and verbal communication — you will work across teams and document what you build.
