Job 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.

Job Responsibility:

  • 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)

Requirements:

  • 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 TypeScript
  • 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 GraphQL-style approaches
  • Experience delivering incremental modernization (POCs, phased rollouts)
  • Strong ability to work with third‑party libraries (Redux, RxJS) and troubleshoot dependency issues
What we offer:
  • medical
  • vision
  • dental
  • life and disability insurance
  • company 401(k) plan
