React UI Architect

Role Summary
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.
Key Responsibilities
• Own the React application architecture end-to-end: project structure, component strategy, routing approach,
and front-end integration boundaries.
• Define and implement engineering standards for the UI codebase: reusable component patterns, conventions,
linting/formatting, PR quality bars, and documentation to keep the system maintainable and scalable.
• Drive front-end decisions considering maintainability and ecosystem health (e.g., community support and update
cadence were part of internal evaluation discussions).
• Implement foundational UI building blocks (navigation, layout, shared components) and deliver one or more key
product modules end-to-end.
• Build UI components with strong accessibility practices in mind; internal discussion highlighted accessibility as a
key consideration in framework choice and implementation approach.
Required Qualifications
• 10+ years of professional software development experience with significant front-end focus.
• Deep, hands-on React experience building production-grade SPAs.
• Proven experience as a hands-on technical Sr. Engineer/lead who has built an application from
scratch (greenfield foundations + delivery).
• Demonstrated ability to work independently with minimal oversight while driving architecture and delivery
outcomes.
• Preferred: Experience modernizing or migrating legacy UI stacks (e.g., older server-rendered UIs) into a modern
React SPA.
• Bachelor's Degree in Computer Science or Related Major
