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 s 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 , and we complete over 350,000 verifications each week. World App is already among the most used wallets globally. Developers are integrating World  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, Space

X, 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 Tech Crunch have all recognized our progress in identity, cryptography, AI, and global‑scale hardware deployment. Our leadership is also named to the Time AI 100.

We are a rapidly growing, highly cross‑functional team that strategically partners with industrial design, optics, software, market operations, and the finance teams to define new product concepts. Join our dynamic team as an Electrical Engineering Lead, and contribute to the development of our next generation proof of human devices. We offer competitive compensation, professional development opportunities, and a collaborative work environment.
