About Quartz Quartz is reimagining wealth management through personalised intelligence. It's the first wealth platform that truly learns from you, understands your goals, and helps you make confident, informed decisions all in one secure platform. Get the experience of a personal banker that works with you 24/7, at a fraction of the cost. About The Role We're looking for a Frontend Developer to build the surface where Quartz users meet Charlie — the mobile and web apps that turn complex financial intelligence into something people can actually use. You'll write TypeScript and React Native day-to-day, collaborate closely with designers on interactions and motion, and make the early UX and engineering decisions that set the bar for how the product feels as it scales. Expect to partner with design on prototypes, and with backend and ML to shape how the product actually behaves. This role is for someone who excels at first principle thinking, cares about craft as much as code, and is comfortable owning features end-to-end — from wireframe to production.
