📋 Description

• Are you a Frontend Developer with a keen eye for design and a passion for innovation? Do you thrive on creating exceptional user experiences from concept to code, leveraging cutting-edge AI tools to bring your visions to life? Ruby Labs Ltd. is seeking a unique and talented UI/UX-oriented Frontend Developer to join our dynamic team in Ukraine. This is an extraordinary opportunity to redefine the role of a frontend developer, empowering you to be the architect and builder of interfaces, without the need for pre-defined design files or a dedicated designer.
• At Ruby Labs, we are at the forefront of creating and operating innovative consumer products across the health, education, and entertainment sectors. We foster a culture of rapid growth, ambition, and a relentless pursuit of excellence. We are not just building products; we are shaping the future of consumer-led experiences. As a UI/UX-oriented Frontend Developer, you will play a pivotal role in this mission, taking ownership of the entire UI lifecycle. You will be instrumental in translating abstract product ideas and high-level requirements into tangible, intuitive, and visually stunning interfaces.
• This role is distinctly different from a traditional designer-to-developer workflow. We are searching for an individual who possesses a deep understanding of design principles, UI/UX fundamentals, and has the practical ability to conceptualize, generate, and implement interface solutions independently. You will be empowered to explore creative directions, utilize modern AI tools to accelerate your design process, and then translate these concepts into production-ready code. Your primary focus will be on the creation and implementation of interfaces, ensuring they are not only aesthetically pleasing but also highly functional and user-friendly.
• Your responsibilities will span the entire spectrum of UI development. You will be tasked with creating UI concepts from the ground up, drawing inspiration from product requirements, market references, or innovative ideas. A key aspect of this role involves leveraging advanced AI-powered UI tools such as Hero UI Chat, Lovable, v0.dev, and Figma AI to rapidly explore design possibilities, generate prototypes, and iterate on solutions. You will be the bridge between conceptualization and execution, ensuring that every interface is structured logically, visually consistent, and adheres to the highest standards of usability.
• The technical foundation of your work will involve implementing these interfaces using modern web technologies. You will be working with Next.js (version 15 and above), React, TypeScript, and Tailwind CSS. A significant part of your contribution will be building robust, reusable, component-based UI structures that form the backbone of our user interfaces. This approach ensures scalability, maintainability, and a consistent user experience across all our products. You will be responsible for ensuring that all interfaces are fully responsive, accessible, and provide a seamless experience across various devices and screen sizes.
• We are looking for a developer who can take full ownership of UI delivery. This means you will be accountable for the entire process, from the initial spark of an idea or requirement to the final, polished implementation in production. Your ability to independently interpret complex requirements and translate them into effective UI solutions will be paramount. This is an opportunity to showcase your end-to-end development skills and make a tangible impact on our consumer products.
• We are not seeking an engineer with a heavy focus on complex architectural patterns. Instead, our ideal candidate is a UI-centric developer who thinks intrinsically in terms of interfaces, user flows, and visual design. You should be comfortable making design decisions, iterating quickly, and delivering high-quality, polished UI elements with minimal external guidance. If you are a proactive, self-motivated developer who is excited by the prospect of shaping user interfaces and leveraging AI to push the boundaries of design, then Ruby Labs is the place for you.
• Join us at Ruby Labs and become an integral part of a fast-growing team that values ambition, innovation, and impactful contributions. This role offers unparalleled opportunities for personal and professional growth, allowing you to develop your skills in a supportive and forward-thinking environment. We believe in empowering our team members to take initiative, drive results, and achieve their full potential.

🎯 Requirements

• Strong understanding of UI/UX fundamentals including layout, spacing, typography, visual hierarchy, and usability principles.
• Proven experience in creating and implementing user interfaces independently, without reliance on dedicated designers or pre-existing design files.
• Hands-on experience utilizing AI tools for UI generation, exploration, and prototyping (e.g., Hero UI Chat, Lovable, v0.dev, Figma AI, Banana AI).
• Basic but recent practical experience with Next.js (15+), React, TypeScript, and Tailwind CSS.
• Demonstrated ability to independently interpret product requirements and translate them into functional and visually appealing UI solutions.

🏖️ Benefits

• Fully Remote Work Environment: Enjoy the flexibility to work from anywhere, promoting a healthy work-life balance.
• Unlimited Paid Time Off (PTO): Take the time you need to rest and recharge, without worrying about tracking your days.
• Paid National Holidays: Enjoy paid time off for national holidays, allowing you to relax and celebrate.
• Company-Provided MacBook: Receive a high-quality Apple MacBook to ensure you have the best tools for productivity.
• Flexible Independent Contractor Agreement: Benefit from autonomy, potential tax advantages, and the freedom to manage your work arrangements.
