We are the Cloud Platform Engineering team, responsible for the infrastructure systems that give the entire organization visibility and control over its cloud resources. We build two critical platforms:
Cloud Cost Management Platform â a billing and cost attribution system that tracks GCP spend across all departments, enables cross-department chargeback, and provides the data foundation for cost optimization across $30M+ in annual cloud spend.
Security & Access Platform â a zero-trust access control system covering Just-In-Time (JIT) access, Attribute-Based Access Control (ABAC), and self-service credential management for all production GCP environments and CI/CD pipelines.
Our work directly impacts engineering productivity, cost governance, and the security posture of the entire company.
