Senior Product Designer (Mobile)

As a Senior Product Designer, you will own the end-to-end problem space - from early discovery to implementation-ready delivery - across both investing and savings products. You will work in ambiguous problem spaces, especially as we expand into savings, helping define problems, uncover user needs, and shape new product experiences from the ground up. You will explore solution directions and translate them into clear, testable designs. Through rapid prototyping - including AI-assisted tools - you will efficiently explore, validate, and refine ideas, moving from early concepts to strong design direction. You will collaborate closely with Product and Engineering to ensure solutions are both user-centered and technically sound. This includes contributing to product copy where needed, clearly communicating design intent, and making trade-offs explicit and intentional. Your work will go beyond individual screens - you will think in systems, patterns, and scalability, shaping consistent and maintainable solutions across the app as we expand into new domains.

Deliver high-fidelity designs, including components, variants, states, edge cases, empty states, and error states Ensure designs are clear, unambiguous, and ready for engineering implementation Design scalable patterns and systems that work across both investing and savings experiences Apply strong interaction design, usability, and accessibility principles Rapidly prototype and validate ideas through usability testing and iteration Collaborate early with engineers (iOS & Android) to validate flows and reduce rework Clearly communicate design intent, trade-offs, and rationale Use prototypes and concise documentation to support decision-making What you need to succeed 5+ years of experience and strong understanding of mobile constraints (iOS and Android patterns, responsiveness, performance, state handling, and platform differences) A proven track record of designing and scaling B2C products Ability to design with technical awareness, not just visual polish Experience working on complex product domains (e.g., fintech, banking, or similarly structured products) Experience working closely with mobile engineering teams in complex product environments Excellent communication skills - able to explain both what you designed and why it works Comfort working in ambiguity and shaping new product areas from early stages

Experience designing for savings, investing, or financial management products Experience using AI in design and development workflows (e.g., UI generation, component exploration, Figma-to-code, prototyping, documentation) Familiarity with mobile tech stacks and design systems (SwiftUI, Kotlin, Jetpack Compose, design tokens, etc.) Experience in regulated environments and understanding of compliance considerations in product design How we hire To learn more about our approach to hiring and how to prepare for your interviews, check out our How we hire section.
