At 3Box Labs we are on a mission to usher in a new era for the web, where data is secure, interactions are trustworthy, and relationships are the basis of connection. We're enabling online experiences that are delightful and integrated while also bolstering privacy and freeing innovation. Our first product, Ceramic, is the building block for composable data on the web and is powering thousands of the world's most ambitious applications.

We're backed by an incredible community and the best investors in the space (USV, Placeholder, Variant, Multicoin) who have deep conviction in our mission.  We are a lean, voraciously curious team from across the globe, with 5 years of expert remote work experience and frequent (and awesome) team retreats to spend time together. We have founded tech startups, written books, won product awards, authored patents, created Ethereum standards, and advised F100 CEOs.

Come help us tackle novel challenges and reinvent how data is managed online. Every one of our roles is remote first (retreat often!). We are committed to building a diverse and inclusive team because we cannot succeed in our mission without it. People that identify with groups traditionally underrepresented in tech are particularly encouraged to apply.
