Senior Product Designer — Mobile

Clear Street Active is a new retail trading product and mobile is a first-class surface. A lot of our users will spend most of their time there, and the experience has to hold up on its own terms, not as a scaled-down version of the web app. We're looking for a Senior Product Designer who thinks mobile-first and has shipped on iOS and Android. We're early enough that you'll be defining the mobile experience before it exists. What you'll do * Own mobile product design across key surfaces * Work closely with iOS and Android engineering to ship * Prototype in the real codebase using AI tooling * Bring a mobile perspective to design system work. Patterns that don't hold up on a small screen need to be caught early. * Keep the mobile and web experiences cohesive alongside the rest of the design team What we're looking for * Deep mobile craft: iOS and Android native patterns, gesture interactions, the details that separate a good mobile product from a great one * Some familiarity with investing or trading, from work or personal use. Not a hard requirement, but you'll need to get up to speed quickly. * Strong product design fundamentals * Can prototype in the real codebase using AI tooling * Works closely with engineering, not around it * High autonomy, no ego Nice to have * Has shipped a consumer fintech mobile product * Deep trading domain expertise * Experience designing across web and mobile in the same product This is a small team. Everyone is building, giving feedback, and in the work together, not siloed by function.
