UX/UI Engineer

Ruby Labs is a leading tech company that creates and operates innovative consumer products across health, education, and entertainment. One of RubyLabs’ portfolio companies is looking for a mid-level UI/UX Engineer to join our team and take full ownership of designing and implementing user interfaces using pre-built component libraries. This role is perfect for a frontend engineer who enjoys working within structured design systems and ensuring high-quality, data-driven user experiences. You will be responsible for both defining the UI structure using existing components and implementing it in code—without relying on a separate designer. If you thrive in a results-driven environment, value autonomy, and enjoy building intuitive, scalable UI without subjective design guesswork, this is the role for you.

• UI/UX design and implementation: Design web interfaces using pre-built components (NextUI, HeroUI, Tailwind).
• Ensure consistency, usability, and accessibility across designs.
• Create wireframes and layouts based on structured design principles.
• Frontend development: Implement designs using NextUI, HeroUI, and Tailwind CSS on top of Next.js and React.
• Develop and maintain scalable, maintainable, and performant UI and reusable components.
• Ensure cross-browser compatibility and responsiveness.
• Collaboration and process: Work with product managers to translate data-driven requirements into UI solutions.
• Ensure seamless handoff between design and development by owning both parts of the process.
• Maintain high coding standards and efficient workflows.

• 2+ years of frontend development experience (Next.js, React, TypeScript, Tailwind).
• Strong understanding of UI/UX principles and ability to work within structured design systems.
• Experience with UI component libraries (NextUI, HeroUI, or similar).
• Ability to design and structure UI without relying on a dedicated designer.
• Proficiency in HTML and CSS, writing clean, maintainable code.
• Familiarity with design tools (Figma, Visily) to work with assets.
• Experience with version control systems (Git).
• Portfolio showcasing at least 5 projects where you handled both UI design and frontend implementation.

• Experience working with design systems and component-based architecture.
• Background in D2C product development or performance marketing.
• Experience optimizing accessibility and usability.
