About the Company:

World is building a real human network designed to accelerate people in the age of AI. As bots and autonomous agents reshape the internet, people, institutions, and applications need a trusted way to confirm who is a real human while preserving privacy. Our products make this possible: the Orb verifies real people, World ID proves it privately, and World App enables and distributes the new applications made possible by this technology. Together, they form a new layer for AI internet.

We’re one of the fastest-growing networks in tech. More than 17 million people across 160 countries have verified with World ID, and we complete over 350,000 verifications each week. World App is already among the most used wallets globally. Developers are integrating World ID to build safer online experiences and create spaces where real people can participate, earn, and be recognized in ways AI simply can’t replicate.

World was founded in 2019 and launched globally in 2023. We are more than 400 people across hardware, software, AI, cryptography, mobile engineering, and global operations. Our teams come from OpenAI, Tesla, SpaceX, Apple, Google, Stripe, Meta, Coinbase, Palantir and MIT Media Lab. We’re backed by leading investors, including a16z, Khosla Ventures, Bain Capital Crypto, Blockchain Capital, Variant, Tiger Global, and Coinbase Ventures, as well as prominent operators and founders across fintech and AI.

World has been featured on the cover of TIME Magazine, highlighted in Fast Company’s Next 5 in Fintech, and explored in a Bloomberg deep dive. The New York Times, Bankless and TechCrunch have all recognized our progress in identity, cryptography, AI, and global-scale hardware deployment. Our leadership is also named to the Time AI 100.

This opportunity is with Tools for Humanity.

The Opportunity

You’ll work on face authentication, our newest verification method that runs entirely on-device. This technology enables users to verify their humanity using just their phone’s camera, expanding World ID access beyond Orb locations.

• Expand: Drive the growth of World ID and World App by building and improving face authentication on iOS, enhancing existing verification methods, simplifying enrollment, and enabling seamless account management to reduce churn.

• Engage: Work closely with our internal ML team to further develop and productionize our face authentication engine, this includes both research tooling and production features.

• Excel: Build core technologies and infrastructure to optimize security, privacy, compliance, reliability, and development velocity for World.

• Extend: Advance an open and decentralized platform for empowering third-party developers to integrate World without relying on proprietary technologies and single points of failure.

You’ll take ownership of key software components; designing, building, debugging, scaling and maintaining them to meet high standards and team objectives.

About You

• You have been designing and developing natively for iOS for some time.

• You have a track record of writing exceptional software, tackling hard problems, and coming up with elegant solutions.

• Experience with camera APIs, integrating native libraries (Rust/C++ via Swift), or on-device ML is a plus.

• Others consistently vouch for your collaboration, prioritization and organization skills, ability to operate in ambiguous and changing conditions, and getting things done.

• You have a demonstrable history of picking up, mastering and applying new knowledge and skills.

• You express yourself clearly, crisply and simply, in writing and in speech.
