About the Company:

Worldcoin is a new, collectively owned global currency that will be distributed fairly to as many people as possible. Worldcoin will launch by giving a free share to everyone on Earth. We believe that this is an essential step to accelerate the transition towards a more inclusive global economy, providing new ways for everyone to share future prosperity. We hope you’ll join us on our ambitious journey.

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

Controlling hardware like motors and current supplies by writing C for microcontrollers on top of an RTOS is a delight for embedded programmers.  Worldcoin's Orb takes this delight to the next level by providing novel hardware—in a device that will interact with billions of people!  There are the usual beautifully executed user interface LEDs that tastefully ebb and flow.  However, a stepper motor-driven gimbal system aims a fully custom optical system that incorporates a liquid lens element that can change focus in milliseconds—and this is fun to program.  There are many other notable hardware components inside an Orb and firmware is needed for multiple scenarios ranging from factory bring up through regular field operation.  The Orb presents a wide variety of engineering challenges that can be very rewarding to work on.

About You

  • Deep knowledge of C, including a detailed understanding of C’s “undefined behaviors”
  • Love of IoT devices like the Orb and delight in collaboratively working with hardware people
  • A good understanding of security, or at least a strong desire to develop a "security mindset"
  • Enjoyment of a fast-paced environment with a lot of action
  • Excellent transparency, where you love to share details of what you're working on that range from architecture to implementation
  • Admiration for team effort with ambition to take the lead on your own projects
  • Excitement for the unknown—you’re always ready to learn something new.
