About the role

Key responsibilities & impact

Design and build the server-side foundation that takes Castle Busters from a client-authoritative game to a competitive, server-validated one.
Build server-side validation for the metagame - currency, card upgrades, chest opens, and progression - staged by risk, replicating economy and reward logic on the server.
Move toward server authority for competitive features, where game state lives in one place and can be trusted.
