About the Team

Scale is at Worldcoin’s core. The Protocol team is responsible for fulfilling this mission in a decentralized way by imagining, building, and maintaining trustless systems that can scale to billions of people. One of the ways we do this is through a privacy-preserving protocol that powers WorldID using state-of-the art cryptography. We are active in the Ethereum ecosystem, and work with the wider community to solve limitations around blockchain scalability. Our team builds Rust services deployed on Kubernetes clusters that generate and verify zero-knowledge proofs and interact with the Ethereum Blockchain and various Layer 2 solutions.

• Work primarily in Rust, with some exposure to smart contracts in Solidity, TypeScript and Go.
• Work on the latest technologies and developments in blockchain and cryptography.
• Contribute to feature development and code reviews.
• Work closely with and learn from experts in domains like AI, cryptography, blockchain all the way to hardware manufacturing.
• Guide and mentor the Protocol team and improve engineering best practices through leading by example
• Take ownership over deployed services that power our scalability solutions.

About You
