Job Description

Senior UI Developer (React)

Environment: On-Prem Enterprise (.NET / C# Backend)

Level: Senior / Lead Contributor

Greenfield Modernization Initiative

Overview

We are hiring a Senior UI Developer to lead the design and development of modern, enterprise-grade React applications. This role is heavily front-end focused (60–70% React) with 30–40% hands-on C#/.NET backend contribution.

This is a true greenfield opportunity — rebuilding legacy applications from scratch using modern technologies and best practices. The ideal candidate is a senior-level engineer who can architect front-end solutions, establish reusable libraries, and work directly with business stakeholders to deliver clean, intuitive user experiences. This is not a maintenance role and not a pure backend position. We are looking for a senior React expert who can lead from the front technically.

Responsibilities

  • Design and build scalable React applications from the ground up
  • Architect front-end structure, state management, and component libraries
  • Lead modernization efforts replacing legacy systems
  • Own UI standards, patterns, and reusable components
  • Translate business requirements directly into functional and polished UI solutions
  • Work directly with stakeholders to understand workflows and user needs
  • Develop and integrate REST APIs using C#/.NET
  • Contribute to backend services where needed (30–40%)
  • Mentor developers and provide technical direction on UI best practices
  • Ensure performance, maintainability, and scalability of solutions

Required Qualifications

  • 7+ years of software development experience
  • 4+ years deep hands-on experience with React (SPA architecture)
  • Strong understanding of modern JavaScript / TypeScript
  • Experience architecting front-end solutions — not just building features
  • Experience building reusable component libraries
  • Solid experience with C# and .NET (API development, integration)
  • Experience working directly with business stakeholders
  • Strong communication skills and ability to lead technical discussions
  • Experience modernizing or rebuilding legacy systems

What This Role Is

  • Senior-level, hands-on builder
  • Front-end owner and technical leader
  • Design-minded engineer without reliance on a UX team
  • Comfortable operating in an on-prem enterprise environment
