User Interface Engineer (Remote)

Role Overview

You will be a contract UI Engineer working remotely to design, develop, and maintain user interfaces that support the training and evaluation of next-generation AI systems. The UI you build helps deliver high-quality, real-world input across domains like finance, healthcare, and engineering.

Responsibilities

• Build and maintain scalable UI components using React and TypeScript.
• Collaborate with product managers, designers, and backend engineers to deliver seamless, user-centric solutions.
• Convert complex technical/business requirements into responsive, accessible, high-performance UI.
• Maintain high standards for UI design, code quality, and performance, including code reviews.
• Identify and fix UI/UX issues to improve usability for global users.
• Mentor peers on front-end engineering standards and contribute to a culture of technical excellence.

Requirements

• 3+ years of professional front-end experience with a strong focus on React + TypeScript (component-based architecture, state management).
• Proficiency in HTML and CSS, plus modern CSS frameworks such as Tailwind CSS or Material-UI.
• Experience implementing wireframes/mockups into pixel-perfect UI using tools like Figma or Adobe XD.
• Strong understanding of front-end performance optimization (e.g., bundle analysis, code splitting, lazy loading).
• Familiarity with Git and CI/CD pipelines and collaborative team workflows.
• Ability to work independently in a remote, async-first environment with clear communication and documentation.

Nice to Have (Not Required)

• Domain experience in AI/machine learning/data labeling is not required; focus is on front-end engineering.
