Worldcoin is hiring a

Web3 Fraud Prevention Team Lead

About the Team:

The Orb Software team writes software and firmware using Rust, C, and Python. Frequent collaborators include the Hardware (bring-up, manufacturing, adding new sensors, etc.), AI (neural networks controlling the autofocus, etc.), and Cloud teams. Orb Software team members are primarily located in Berlin and San Francisco, although some work remotely.

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 Opportunity:

Worldcoin is currently building up its vitally important fraud-monitoring team as we head towards mass production and the global launch of the Orb. As team lead on the fraud prevention team, you will manage the feature roadmap for everything related to fraud prevention in collaboration with cross functional teams. Such systems include CNN based presentation attack detection as well as anomaly detection. You will be involved in deploying our hardware device to unsecured environments while maintaining the system’s overall integrity. The challenge is to develop scalable strategies for preventing fraud while creating a positive user experience. Since system integrity is essential for Worldcoin’s mission, this role is critical for the company.

You will coordinate cross-functionally to design and implement systems to monitor devices in the field for fraudulent activity of any kind. You will interact closely with the AI, on-device software, backend, economics and growth teams. Given that one can always take further preventative measures to make attacks more difficult—ultimately preventing fraud—this role effectively provides unlimited opportunity.

In this role you will:

• Build the fraud prevention team
• Architect supervised and unsupervised systems to detect potentially fraudulent activity and deactivate devices.
• Coordinate cross-functional work streams with the On-Device Software, AI and Backend teams
• Develop key indicators to serve as early warning risk indicators for potentially fraudulent activity
• Set policies on when potential fraud should be reviewed vs automatically blocked
• Work with engineers across the company to collect better metrics that improve fraud detection
• Balance user privacy with fraud risk
• Develop preventative measures to reduce the number of fraudulent activities

About You:

• 3+ years of relevant professional experience
• You enjoy to do occasional hands-on development work
• You have lead an engineering team before
• Experienced with infrastructure, data science and dashboard development
• Thrive in a fast-paced environment that is continuously evolving
• Decisive, yet open to learning: you will make many critical decisions every day impacting large numbers of users. You are willing to make difficult decisions in an ambiguous environment and quickly learn and iterate from your experiences.
• Analytical and skilled at using data to drive decisions.
• Creative yet pragmatic and solutions oriented
• Care about the user and are making thoughtful balanced decisions weighing user experience and privacy vs the risk of fraud
• Deeply curious and creative
• Bonus
• Knowledge about IoT devices
• Knowledge about on-device Software & Hardware security
• You have scaled a team before
