Role Overview

We’re looking for a Principal UI / Interaction Designer to lead the UI strategy, interaction design, and design system foundations for our next-generation native mobile app. In this role, you will define the standards for best-in-class mobile design, build and scale the mobile design system, and establish the interaction models and principles that guide our product design teams. You will partner closely with product, engineering, research, and design leadership to set vision, drive execution, and elevate design craft across the organization.

This is a highly impactful, strategic role for a designer who blends deep mobile expertise with systems thinking, craftsmanship, and leadership.

What you’ll be doing Lead the UI Vision

• Own the end-to-end UI design direction for our next-generation native mobile experience across iOS and Android.
• Define and document mobile UI principles, interaction guidelines, motion patterns, and design philosophies that anchor the product.

Establish & Evolve the Mobile Design System Architect robust mobile design system-components, patterns, tokens, interaction models‑and partner with engineering to ensure scalable implementation.

Drive system governance, maintain visual coherence across journeys, and proactively evolve the system based on product needs.

Ensure accessibility compliance, system-wide consistency, and performance considerations in component and pattern design.

Design High‑Fidelity, Beautiful, and Functional UI

• Create refined UI screens, flows, and prototypes with exceptional attention to detail, craftsmanship, and platform‑specific conventions.
• Translate user and business needs into intuitive, polished mobile interfaces that simplify complex financial and healthcare journeys.

Influence Design Direction Through Craft & Thought Leadership

• Shape product strategy by advocating for clarity, usability, and interaction efficiency.
• Partner with product managers and engineering leaders to ensure UI decisions are grounded in feasibility, system architecture, and long‑term scalability.
• Identify experience gaps and advocate for improvements that deliver measurable impact across key journeys (claims, contributions, spending, investments, card management, onboarding, etc.).

Collaborate, Mentor, & Elevate the Team

• Mentor product designers and UI designers, raising the bar for craft, visual quality, motion design, and systems thinking.
