Senior Product Designer — Mobile

About the job

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.
