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.

People spend fifteen seconds with an Orb, but a lifetime with the Worldcoin App. As such, the App team plays a critical role in fulfilling our mission. Using the App, people can join the Worldcoin network, participate in decentralized finance in a friendly and self-custodial manner, and use their WorldID to unlock services across the ecosystem.

The Wallet squad is the group of engineers, product managers, designers and data scientists responsible for imagining, building, and maintaining the foundational crypto wallet primitives, as well as the decentralized finance products people around the world access through the App.

  • Lead by example by contributing as an engineer in feature development, code reviews, and architecture design.
  • Help improve engineering processes and implement best practices.
  • Be involved in hiring a team of highly skilled engineers. (We expect to scale significantly in the coming months.)

About You:

  • Excellent communication, problem-solving, and conflict resolution skills.
  • 3+ years of experience as a software engineer and 1+ years of experience leading a team of engineers.
  • Experience in Mobile, Backend, and Blockchain development required. Prior experience specifically in Ethereum (or EVM compatible chains) and working on FinTech products required. Basic cryptography experience is preferred, but not required.
