Slack enterprise key management: Senior to staff lessons
summary
Built a working Slack Enterprise Key Management system that integrates with AWS KMS, prototypes the end-to-end flow, and actually ships. Concrete tradeoffs: caching keys with a cache TTL five minutes reduces latency but causes frequent KMS calls and a surprising KMS bill for large orgs; backfill, search, and immutable audit logs add complexity. Teaming and automation matter — shared components and generated interfaces cut repeated work — and the project ultimately shipped on time.
