This role sits at the core of a regulated, API-driven brokerage platform, where you will own a critical part of the accounts infrastructure powering millions of brokerage accounts globally. You will focus deeply on one domain within the accounts stack—such as KYC and identity verification, account structures, or multi-account systems—while shaping the developer experience for partners who build directly on top of these APIs. Working at the intersection of product, engineering, compliance, and legal, you will define and ship scalable account capabilities that must meet strict regulatory standards while remaining simple for developers to integrate. Your impact will be measured by real-world adoption, partner success, and production usage rather than feature output alone. This is a high-ownership role in a fast-paced, globally distributed environment where product decisions directly influence financial infrastructure at scale.
