About the role

Ruby Labs is seeking an AI UI/UX Developer — a designer-turned-developer who leverages AI tools as a force multiplier to ship exceptional interfaces at startup speed. You combine strong design taste with frontend engineering skills and treat AI-assisted workflows (code generation, design-to-code pipelines, prompt-driven prototyping) as your default operating mode, not an add-on.
This role requires someone who can take strategic direction, rapidly explore multiple design directions using AI, and independently deliver production-ready interfaces — owning the full loop from concept to deployed code. You'll be responsible for both designing exceptional UI experiences and implementing them, ensuring every detail meets our excellence standards while moving significantly faster than traditional workflows allow.

Key Responsibilities

• AI-accelerated design & implementation — Design and build exceptional interfaces using Figma, AI design tools (v0.dev, same.new, Hero UI Chat, Bolt, Lovable), and AI code assistants (Cursor, Claude Code, GitHub Copilot). Start from high-level references and autonomously deliver polished results.

• Production-ready frontend development — Develop and ship code using Next.js 14+, React, TypeScript, and Tailwind CSS with meticulous attention to detail. You own quality end-to-end — there is no QA layer between you and production.

• Scalable component architecture — Build and maintain structured design systems (HeroUI, shadcn/ui) ensuring consistency, accessibility, and cross-browser compatibility. Use AI to scaffold components rapidly, then refine manually where AI output falls short.

• Prompt engineering for design & code — Write effective prompts for design and code generation tools. Know when AI output is production-ready and when it requires manual intervention. Continuously refine prompt strategies to improve output quality and speed.

• Autonomous interface delivery — Translate strategic requirements into intuitive user interfaces. Collaborate efficiently with product teams while maintaining design autonomy and making sound UX decisions independently.

• AI workflow optimization — Continuously evaluate and integrate emerging AI tools into your workflow. Establish repeatable AI-assisted patterns that the team can adopt to increase overall velocity.

Qualifications

• Designer-to-developer background — Started as a UI/UX designer with advanced Figma expertise before transitioning to frontend development. Strong visual taste and layout instincts are crucial.

• AI-native workflow — Demonstrated experience using AI design and code generation tools daily (v0, Cursor, Claude Code, Copilot, Bolt, or similar). You don't just "know about" these tools — they are integral to how you work.

• Frontend proficiency — 3+ years of hands-on experience with Next.js, React, TypeScript, and Tailwind CSS. You can read, debug, and refactor AI-generated code confidently.

• Critical AI output evaluation — Ability to quickly assess AI-generated designs and code for quality, accessibility, and production-readiness. You know where AI hallucinations and pattern failures typically occur and catch them before they ship.

• Autonomous execution — Proven ability to create complete interfaces from high-level references with exceptional attention to detail, working without constant guidance or QA oversight.

• Fluency in Russian and/or Ukrainian language.

Nice to have

• Experience building and maintaining design systems and component libraries at scale.

• Experience with AI-assisted testing and visual regression workflows.

• Familiarity with motion design and micro-interactions (Framer Motion, CSS animations).
