Job description

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

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
• 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)
• Experience architecting front‑end solutions — not just building features
• 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
