Senior Application Security Engineer at Worldcoin

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 will generate a hash of each user's iris and submit it to Worldcoin's trustless backend (built on Ethereum). For more details on how the Orb is part of Worldcoin's privacy-preserving approach to Proof-of-Personhood, see How the Launch Works.

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

For Worldcoin to launch successfully on a global scale, we need to both ensure fairness and build trust with our users. Therefore, it is essential to prevent fraud, protect privacy, and ensure availability.

Beyond regular company security the goal of security at Worldcoin is to deploy an edge device to unsecured environments. We consider a wide range of threats that span tampering with the device, spoofing the device as well as backend attacks.
