- Experience building production applications on cloud platforms (AWS, Azure, GCP) using Docker and Kubernetes
- Experience building multi-tenant SaaS platforms with strong tenant isolation - particularly around access controls, data scoping, and account hierarchy
- Hands-on experience with RBAC, authorization, authentication, or SSO systems, and the patterns that make them consistent and auditable at scale
- Experience with licensing, subscription, entitlement, usage metering, or billing-adjacent systems - especially where correctness and consistency across services matter
