KIBO Commerce - Senior User Interface Developer - React.js/TypeScript

About This Role :

As an early career UI engineer, you will join KIBO at the forefront of the modular commerce revolution where you will orchestrate AI tools to build high-performance interfaces. You are an AI-native developer who leverages modern agents to rapidly prototype, style, and test React components while maintaining production standards. Your work will ensure that AI-generated UI code meets strict requirements for accessibility and pixel-perfect design across our global commerce platform.

What You'll Do :

• Build responsive web components using React, TypeScript, and Tailwind CSS.
• Accelerate the creation of UI layouts and design system components using AI coding tools.
• Provide AI tools with specific context like style guides and JSON schemas to generate high-quality UI code.
• Generate comprehensive unit tests using Jest and Playwright to ensure stability across browsers.
• Transform Figma designs into functional React code through AI-assisted workflows.
• Audit frontend performance to optimize Core Web Vitals and efficient rendering.

What You'll Need :

• 5+ years of professional experience in frontend development with a strong focus on React.
• Proven experience owning features end-to-end, from design through deployment.
• Deep fluency with AI-assisted development tools (Claude Code, Cursor, Copilot, or similar) as a core part of your daily workflow.
• Strong proficiency in React, JavaScript, TypeScript, and utility-first frameworks like Tailwind CSS.
• Demonstrated experience architecting component libraries or design systems, not just building individual components.
• Solid grounding in design principles - typography, layout, accessibility (WCAG), and interaction design.
• A track record as a strong problem solver who can debug ambiguous issues and make sound architectural trade-offs independently.
• Experience writing frontend tests with Jest, React Testing Library, or Playwright.
• Solid understanding of Git and collaborative workflows including code reviews.
• Excellent communication skills, with experience giving technical direction to other engineers.
• Familiarity with Claude Design or similar AI-native design/prototyping tools.
