Senior Android Kernel Engineer

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 would be with Tools for Humanity.

At all levels we consider ourselves builders and hackers. We are looking for someone who is versatile enough to work on the strategy of the entire subsystem all the way through to code implementation.

About the Orb:

The Orb is a secure biometric imaging system, designed to seamlessly prove humanness in a privacy-preserving way. It locally analyzes biometric images from its sensor suite and then transfers them to user devices, with no backend for image storage/processing. These Orb-authenticated images are used to verify World IDs, allowing users to prove they are unique humans without revealing any additional information. The Orb is designed to be easy to use, while still meeting exceptionally strong requirements for security and privacy.

About the Opportunity:

The Device Software team owns all software running on the Orb. This includes the biometric imaging system, on-device fraud detection, and a security-hardened operating system. Additionally, the team is responsible for supporting manufacturing, test automation, and hardware bring-up. All core software is written in Rust and runs in a custom GNU/Linux OS on the NVIDIA Jetson platform.
