About the Company:
Worldcoin (www.worldcoin.org) 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 (www.worldcoin.foundation) is the protocol’s steward and will support and grow the Worldcoin community until it becomes self-sufficient.

It helped launch Worldcoin and continues to provide support to the Foundation, in addition to operating the World App.
This opportunity would be with Tools for Humanity.
About the Orb:
Worldcoin's launch requires a "Proof-of-Personhood": a way to determine someone is human (not a bot) and hasn't already claimed their free share of Worldcoin. This is why we developed the Orb.
The Orb is an advanced biometric imaging device, custom-designed for Worldcoin's launch. Orbs are deployed to a global network of operators, who use the device to onboard new Worldcoin users. During this onboarding, the Orb generates an encoding of each user's iris and submits it to Worldcoin's backend. For more details on how the Orb is part of Worldcoin's privacy-preserving approach to Proof-of-Personhood, see the Worldcoin whitepaper.
The Orb solves a fierce combination of engineering and UX challenges, centered around image quality, security, and ease-of-use. Each device has an advanced iris imaging system, designed to work consistently across real-world lighting conditions. An additional suite of sensors feeds into an onboard fraud detection system, enabling use in unsecured environments. These systems are combined in a sleek industrial design with a simple, minimalist user interface.
About the Team:
The Cloud team strives to build secure, low-latency systems that operate on a billion-plus user scale, incorporating data science, AI, crypto, fraud-prevention and many other components to power everything from Orbs to user wallets.
