One of the RubyLabs’ portfolio companies is looking for a Mid 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.

• 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.

• Implement designs using NextUI, HeroUI, and Tailwind CSS on top of Next.js, React.

• Develop and maintain scalable, maintainable, and performant UI and reusable components.

• Ensure cross-browser compatibility and responsiveness.

• 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 & 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.
