Whether we are [e.g., simplifying cross-border payments, democratizing investment, or building the next generation of credit], you will be solving high-stakes challenges around security, trust, and financial inclusion.

We’re seeking a talented developer to help build our platform from the ground up. As a critical member of a dynamic and highly-motivated team, you will take a critical developers role, and will be responsible for designing & coding new functionality from scratch.
