Sr React Developer

We have partnered with our client in their search for a Senior React Developer to work remotely.

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.

• React application architecture end‑to‑end: project structure, component strategy, routing approach, and front‑end integration boundaries.
• 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.

• React + Type Script expert; delivered large‑scale SPAs and set coding standards
• Front‑end architecture for modular apps (admin/settings/case management separation)
• React state management strategy and governance (consistent patterns across team)
• Accessibility‑first development (WCAG/ARIA/focus/keyboard; a11y testing)
• Design system / component library integration; reusable, consistent UI components
• UI entitlements: RBAC + feature toggles for module visibility and phased release
• SPA authentication/session integration (token handling; secure flows; timeouts)
• API integration patterns (BFF/aggregation/Graph
  
  QL‑style thinking to reduce coupling)
• Incremental modernization delivery (POCs, phased rollout, minimize disruption)
• Solid foundation in working with third‑party libraries (Redux, RxJS) and debugging dependency conflicts.

• 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.
