Responsibilities

Social graph and identity. Build the graph: users, profiles, friends and follows, guilds, roles, permissions and moderation. It has to stay correct under concurrency and abuse, and fast as the graph grows

Financial and cosmetic economy. Take point on implementing currencies, balances, drops, crafting, cosmetics and entitlements, including reconciliation with on-chain assets and commerce. Every transaction must be idempotent, auditable and reversible

Social product. Chat, timelines, feeds and notifications, built as reusable backend capabilities rather than one-off features. rather than one-off features

API model. Implement contract-first, versioned APIs, and help evolve the contracts with the architect so frontends, mobile and third-party clients can build on them

Raise the bar. Bring hard-won experience to design reviews, testing and code review, and mentor others on the team
