Senior Product Designer — Mobile

Role overview Shape the mobile experience for a new retail trading product, treating iOS and Android as full product surfaces rather than extensions of a web app. You’ll own key mobile journeys from early design through implementation, working closely with engineers and the wider product design team as the experience and its patterns take form.

Responsibilities - Lead design across important mobile product areas, from user flows to interaction details. - Partner with iOS and Android engineers to take designs into production. - Build and evaluate prototypes in the product codebase with AI tools. - Bring mobile usability needs into the evolving design system and flag patterns that do not translate well to small screens. - Coordinate with designers working on web so the product feels coherent across platforms.

Requirements - Experience shipping mobile products on both iOS and Android, with a strong grasp of native conventions and gesture-based interaction. - Strong product design fundamentals and attention to the details that make mobile experiences feel polished. - Ability to prototype within a codebase using AI tooling. - A collaborative approach to engineering and comfort contributing directly to implementation discussions. - Independence, sound judgment, and willingness to adapt when new information changes the direction. - Some familiarity with investing or trading, or the ability to learn the domain quickly.

Nice to have - Experience shipping a consumer fintech app. - In-depth knowledge of trading products and workflows. - Experience designing for web and mobile within the same product.

Benefits and work setup The role is on a small, hands-on team where people build together, exchange feedback, and contribute across functional boundaries.
