React User Interface (UI) Developer

Frontend (UI) React Developer

Location: West Palm Beach, FL (Onsite – 5 days/week)**

Type: Full-time

Salary: $80K – $110K base

OVERVIEW

We are seeking a Sr. Frontend React Developer to support the development of an AI-driven consumer platform.

This is a hands-on, product-focused role — you will be responsible for building and improving core user-facing features in a fast-moving, early-stage environment.

The ideal candidate is a strong React developer who can execute independently, integrate with backend systems, and has solid UI instincts — someone who can make clean, intuitive interface decisions without relying heavily on a separate design function.

WHAT YOU’LL DO

• Build and maintain React-based user interfaces for a live product
• Integrate with backend APIs and real-time data systems
• Develop responsive, functional UI components focused on usability and performance
• Make practical UI/UX improvements (layout, flow, usability) as you build
• Work closely with product and backend teams to ship features quickly
• Improve and optimize existing frontend code and application performance
• Debug issues and contribute to ongoing product iteration
• Write clean, maintainable code with minimal oversight

WHAT SUCCESS LOOKS LIKE

• Features are built and deployed quickly and reliably
• UI is clean, intuitive, and improves over time
• Product iteration moves forward without bottlenecks
• Strong collaboration with backend and product teams

REQUIREMENTS

• 3–5+ years of professional experience in React development
• Strong proficiency in JavaScript (ES6+), HTML, and CSS
• Experience integrating with REST APIs
• Solid understanding of React fundamentals (hooks, state, component architecture)
• Ability to work independently and ship features end-to-end
• Comfortable working in a fast-moving, early-stage environment
• Ability to make basic UI/UX decisions (layout, spacing, usability, flow)

NICE-TO-HAVE

• Experience with real-time data (WebSockets or similar)
• Familiarity with TypeScript
• Experience working on consumer-facing or app-based products
• Exposure to AI-driven or conversational interfaces

PORTFOLIO REQUIREMENT

Candidates must be able to share 2–3 examples of live products or applications they have built or contributed to.

We are looking for:

• Real, working applications
• Clean, usable UI
• Evidence of frontend ownership
