Responsibilities

Deliver great capacity and exceptional UX: Improve World Chain block execution throughput to 100M gas per second and shorten block confirmation time so transactions are executed in a few seconds on average at predictable low fees. Make AMPC production-ready so uniqueness checks stay fast and reliable under surge. Publish simple public SLOs and dashboards so developers see inclusion, backlog, and cost clearly
10-year architecture roadmap: Codify a durable plan from today’s OP Stack baseline to the end-state protocol at global scale. Make crisp calls on validity proof, data availability, state growth, and sequencer design/strategy, with the why captured in ADRs and a staged migration plan. Prove the path with a public testnet and a safe, reversible mainnet cutover plan
Decentralization: Design a credible decentralized sequencer strategy with automatic failover and a clear path to permissionless entry. Distribute AMPC and other critical services across independent operators with SLAs, telemetry, and third-party reviews. Align fees and incentives, including World ID Fees, so neutral parties can run core infrastructure sustainably
Interoperability and DevX: Ship SDKs for e.g. uniqueness and credential attestations that let developers integrate once and run across EVM, mobile, and at least one non-EVM stack. Keep APIs stable and deterministic so reads and writes behave the same under load. Provide reference apps and tests so first integrations land the same day and stay fast as usage ramps
Team and technical visibility: Build a senior, co-located SF team across protocol, ZK, security, and infra, and hire 8-12 exceptional ICs with clear bars. Lead hands on with specs, code reviews, on-call, and a cadence of capacity reviews, chaos drills, and postmortems. Publish research and standards work so the protocol’s direction is legible to partners and the community
