Position: Senior Staff/Principal Embedded Software Engineer, Orb
About the Company

World is a network of real humans, built on privacy-preserving proof-of-human technology, and powered by a globally inclusive financial network that enables the free flow of digital assets for all. It is built to connect, empower, and be owned by everyone.

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.

In this role, you will play a key role in advancing the Orb’s software to reach new levels of scale, decentralization, and performance. This includes projects like porting software to Android‑based systems, optimizing image capture/processing code, and supporting software verifiability.

Your work will be regularly deployed to our global fleet of Orbs used by millions of people worldwide, and will play a critical role in scaling the World network to billions.

We strongly encourage you to apply for this position if you are motivated by World’s mission, have exceptional software engineering abilities, and thrive in a fast‑paced environment.
