• Solid distributed-systems foundation: idempotency, backpressure, delivery semantics, and message queues

Nice to have

• multi-cloud a strong plus
• Experience operating systems at high scale (high QPS, large data volumes)
• Depth in auth and security: secrets management (Vault), mTLS, RBAC, OIDC/SAML, network policy
