Front End Engineer

Description

We are modernizing our product UI, replacing a legacy front-end with a modern React application. This effort is a full UI rewrite and redesign focused on improving usability, maintainability, and long-term scalability—rather than a screen-for-screen conversion.

We are seeking a 10+ years experienced React engineer who has architected and built enterprise React applications from scratch: defining front-end architecture, setting engineering standards, and delivering critical modules hands‑on with minimal oversight.

Preference for candidates who have led migrations from legacy UI stacks into modern SPA frameworks.

• Own the React application architecture, including project structure, component strategy, routing, and integration points.
• Establish and maintain UI engineering standards such as component patterns, naming conventions, linting/formatting rules, PR guidelines, and documentation.
• Make front‑end technology decisions with long‑term maintainability and ecosystem stability in mind.
• Build core UI elements like navigation, layouts, shared components, and deliver major product modules end to end.
• Develop UI components with strong accessibility practices (WCAG/ARIA/keyboard interactions).

• 10+ years of professional software development experience with a strong front‑end focus.
• Deep, hands‑on React experience building production‑grade single‑page applications.
• Proven experience leading and building applications from scratch.
• Ability to work independently with minimal direction.
• Bachelor's degree in Computer Science or a related field.
• Experience migrating or modernizing legacy UIs into modern React SPA frameworks.
• Expert‑level React and Type Script; experience delivering large‑scale SPAs and defining coding standards.
• Strong front‑end architecture skills, especially for modular applications.
• Proficiency with state management approaches (e.g., Redux) and maintaining consistent patterns across teams.
• Accessibility‑first development practice and familiarity with WCAG and ARIA.
• Experience with design systems and reusable component libraries.
• Knowledge of UI entitlements such as RBAC and feature toggles.
• Experience implementing SPA authentication and session management.
• Familiarity with API integration patterns like BFF or Graph
  
  QL‑style approaches.
• Experience delivering incremental modernization (POCs, phased rollouts).
• Strong ability to work with third‑party libraries (Redux, RxJS) and troubleshoot dependency issues.
