Job Summary

We are seeking a highly skilled Senior UI Engineer to focus on building scalable, reusable, and generic UI libraries. The ideal candidate will think in terms of platforms and design systems, enabling multiple applications and teams through well‑designed, well‑documented UI components. This role requires strong problem‑solving skills, deep expertise in React, and experience with design systems such as Carbon, Material UI, or similar frameworks.

Responsibilities

• Design, build, and maintain reusable UI component libraries and design systems used across multiple applications.
• Develop generic, configurable, and extensible components instead of application‑specific implementations.
• Collaborate with UX designers to translate design tokens, patterns, and guidelines into scalable UI components.
• Ensure consistency in theming, accessibility (WCAG), responsiveness, and performance across all components.
• Architect and implement solutions that support multiple consuming applications.
• Review code and mentor junior engineers on best practices and design system principles.
• Identify performance, usability, and maintainability issues and propose robust solutions.

Mandatory Skills

• Strong expertise in React (hooks, context, composition patterns, performance optimization).
• Hands‑on experience with design systems such as Carbon, Material UI, or similar (Chakra, AntD, etc.).
• Strong knowledge of HTML5, CSS3, modern CSS (Flexbox/Grid), and component‑level styling.

Preferred Skills

• Experience with Storybook, documentation sites, or design system tooling.
• Knowledge of monorepos, build tools, and package publishing (npm, internal registries).
• Familiarity with accessibility standards (ARIA, WCAG).

Qualifications

• Excellent problem‑solving and analytical skills.
• Ability to break down complex UI and architectural problems into clean, reusable solutions.
• Strong ownership mindset and attention to detail.
• Good communication skills and ability to collaborate with cross‑functional teams.
