About this role

This mid-career UI/UX Designer joins the Customer Product team responsible for PAY ID, a shopping service connected to BASE’s merchant ecosystem. The product supports consumer shopping while also creating value for shop owners, with work spanning discovery, payment, and buy-now-pay-later experiences.

The role covers user-problem definition, experience and user-flow design, wireframes, UI design, prototyping, requirements and specification discussions, and validation from the early stages of product development. The designer will use Figma, AI tools, and HTML, CSS, and JavaScript for prototypes and implementation-oriented outputs, working with engineers, product managers, and business teams. Responsibilities also include design-system and component improvements and promotional design.

Applicants must have UI/UX design experience for iOS or Android apps, or mobile-based web services or applications; experience leading UI improvements from user problems; practical Figma or equivalent UI design and prototyping experience; and experience collaborating with engineers or product managers on implementation-aware design. Experience using AI tools, creating simple UI implementations or prototypes with HTML, CSS, or JavaScript, and submitting a portfolio are also required.
