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.
