About the Role

As a UI/UX Designer, you will shape the visual and functional interface of our app and website, from the initial wireframe to the finished interface. You will think user-centrically, considering the feel of a flow, points of friction, and how an idea becomes an intuitive interface that aligns with the brand. You will collaborate closely with the CRM & Digital Experience Manager to align design decisions with real user data and conversion goals. You will also coordinate with the Brand & Graphic Design team to ensure a consistent visual language across marketing assets, landing pages, and product interfaces.

Collaborate with Tech/Development on design implementation (handoff, reviews).
Align with Brand & Communications (Graphic Design) for a consistent visual language between marketing and product.
Ensure UI consistency and error-freeness on the website & app (visual QA).
Maintain component libraries and design tokens.

Requirements
