You've been the person others go to when correctness or scale gets hard. * You've built something where correctness around value mattered: payments, ledgers, marketplaces, virtual economies, entitlements * You've built social systems: graphs, permissions, feeds, chat, moderation * Strong relational data modeling: schema design, indexing, query design, migrations on live data * You write clearly. Specs and design docs are part of the job. Good to have * In-game economies or live-ops: drop tables, sinks and faucets, exploit response * Real-time systems (WebSockets, SSE) * Web3 identity and assets: wallet signatures, on-chain indexing * Founding-engineer or 0 1 experience * Systems programming (C/C++/Rust/Zig) ## Description * Social graph and identity.

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.
