This is a dual role. You will create the designs yourself, in Figma, and then bring them to life in React.js and React Native with Expo. You own the experience end to end, from the first wireframe to the shipped, responsive interface. We are not looking for someone who only implements other people's mockups. You will be the person deciding how a feature should look and behave: mapping the user flow, designing the screens, prototyping the interactions, and then writing the code that makes it real. That means strong design judgment matters as much as strong engineering skills here. You will work closely with product and backend engineers to ship features that feel fast, look right, and are genuinely easy to use. This role suits someone who is equally comfortable in a design file and a code editor, cares deeply about the details of the user experience, and wants full ownership of front end features from concept through production. ## Key Responsibilities - Design: - Own the UI/UX for front end features: take a problem or product idea and design the flow, screens, and interactions for it. - Create wireframes, mockups, and interactive prototypes in Figma, and iterate on them based on feedback. - Make the call on layout, visual hierarchy, typography, color, spacing, and interaction patterns so the result is clear and easy to use. - Define and maintain a consistent visual and interaction language across web and mobile. - Design the full picture, including the states that are easy to forget: loading, empty, error, edge cases, and responsive breakpoints. - Frontend Development: - Build and maintain web applications with React.js and React Native with Expo. - Collaborate with product and backend engineers to ship features that feel fast, look right, and are genuinely easy to use. - Ensure the user experience is consistent, intuitive, and responsive across all devices.
