Own the database platform behind Robinhood's brokerage — no downtime during market hours
Robinhood's Storage Platform team runs the relational (Postgres/Aurora), key-value (DynamoDB), and caching systems that thousands of databases and hundreds of caching clusters depend on. This interview probes whether you can design connection pooling, query routing, and automation that hold up under strict brokerage uptime targets, and whether you've actually carried the on-call pager for systems like this.
