About the Company:

Worldcoin is an open-source protocol, supported by a global community of developers, individuals, economists and technologists committed to expanding participation in, and access to, the global economy. Its community is united around core beliefs in the inherent worth and equality of every individual, the right to personal privacy, and open and public collaboration. These beliefs are reflected in what the community is building: a public utility to connect everyone to the global economy.

​

The Worldcoin Foundation is the protocol’s steward and will support and grow the Worldcoin community until it becomes self-sufficient. Tools for Humanity is a global hardware and software development company. It helped launch Worldcoin and continues to provide support to the Foundation, in addition to operating the World App.

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.

About the Opportunity

This is a unique opportunity to lead the development and roadmap of a significant component of our Protocol, which allows for privacy at-scale. This is the first step in our roadmap towards a privacy-preserving digital identity ecosystem.

We are looking for Senior Rust Engineers at varying levels.

In this role, you will:

• 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

• An advocate for always delivering high-quality code.
• Deep expertise developing services in Rust.
• Prior experience with Ethereum, Layer 2 scalability or zero-knowledge applications are nice-to-haves, but not required.
• A curiosity and passion for Web3, open-source code, privacy and digital identity.
• A bias towards action and willingness to roll up your sleeves to get things done.
• Self-driven - you’re not afraid to take risks and make big bets.
