Senior UI/UX Developer (AI-focused)

Ruby Labs is a tech company with a portfolio of consumer products in health, education, and entertainment (100M+ annual users). We seek energetic professionals who love their work and are ready to push forward proactively to achieve exceptional results. We are seeking a Senior AI UI/UX Developer, who combines strong design taste with frontend engineering skills and treats AI-assisted workflows (code generation, design-to-code pipelines, prompt-driven prototyping) as the default operating mode, not an add-on.

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 — 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 English languages.

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).

We offer:

• Fully remote work (within ±4h of CET).

• Unlimited PTO + paid national holidays.

• Company-provided MacBook.

• Flexible Independent Contractor agreement with tax advantages.
