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.  Tools for Humanity (www.toolsforhumanity.com)  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.

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

The Orb Software team is a small group of industry experts, software generalists, and passionate hackers - collectively driven by Worldcoin’s ambitious mission. We're responsible for all software running on the Orb, plus software for manufacturing, automated testing, and fleet management. The multidisciplinary nature of the project requires us to work closely with Security, Backend, Hardware, and AI & Biometrics teams.

Our team embraces the challenges involved in bringing the Orb to life. In this pursuit, we value first principles thinking, pragmatism over perfection, and the sanctity of deep work. We empower each other to own large projects end-to-end, and strive for excellence as a team.

About the Opportunity

In this role, you will help build the Orb's core features, which include biometric image capture, advanced anti-fraud checks, and secure backend communication. You will use Rust to manage multiple real-time sensor streams and integrate tightly with custom neural networks. Along the way, you'll work closely with specialists in embedded systems, security, and machine learning.

Your work will be regularly deployed to our global fleet of thousands of Orbs. The correctness, performance, and security of your code will be a critical factor in enabling millions of people to participate in Worldcoin!

About You

We strongly encourage you to apply for this position if you are motivated by Worldcoin's mission, have exceptional software software engineering abilities, and thrive in a fast-paced environment.

We're especially interested if you have:

  • 5+ years experience in systems programming, robotics, IoT devices, or related fields.
  • Extensive experience using Rust in real-world applications.
  • Familiarity with GNU/Linux and device trees.
  • Experience building security-critical applications.
  • Excellent communication and project management skills.
  • A mission-driven and team-oriented mindset.

*Candidates with strong C/C++ experience instead of Rust are also encouraged to apply.
