Senior Product Designer — Mobile

Clear Street · New York · Posted 2026-09-30

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.
