UI Developer III

The UI Developer III role is primarily focused on leading the implementation and delivery of clean, usable, modern user interfaces that improve our platforms while setting a high standard for front-end engineering quality.

This position involves building new features in React, maintaining and modernizing existing platform features, and helping establish style guides, reusable patterns, modular components, and interface standards for modern UI development.

Effective communication is important because the role works closely with developers, designers, product owners, project managers, and other stakeholders to understand requirements, technical constraints, user experience goals, and long-term platform direction. As a senior position, the UI Developer III is expected to guide practical technical decisions, push design capabilities forward, mentor less experienced developers, and help the broader team deliver maintainable, accessible, and high-quality user experiences.

• Help establish, evolve, and promote style guides, reusable patterns, modular components, and standards for modern UI development
• Lead prototyping, solution exploration, and technical feasibility discussions for complex interface problems
• Lead on architectural and system design decisions that affect front-end maintainability, performance, scalability, and user experience
• Effectively communicate technical and practical design considerations, trade-offs, risks, and limitations throughout the design and delivery process
• Provide guidance, mentorship, and constructive feedback to other developers through code reviews, pairing, and day-to-day collaboration
• Implement unit tests and improve front-end test coverage for new and existing features
• Apply strong attention to detail in code quality, performance, usability, accessibility, maintainability, and long-term platform consistency
• Model responsible use of AI-powered development tools to accelerate delivery, improve problem solving, and support team learning while maintaining strong accountability for code quality, security, maintainability, and technical understanding
• Other duties as assigned

Required

• 10+ years of production-ready software development experience building and shipping user interfaces
• 4+ years of production experience shipping applications with modern front-end frameworks such as React, Angular, Vue, or similar; React preferred
• Strong ability to implement attractive, usable interfaces with excellent attention to visual detail, usability, and accessibility
• Advanced understanding of HTML, CSS, JavaScript or TypeScript, and modern front-end development practices
• Ability to innovate and creatively implement practical, maintainable solutions to uncommon or complex interface challenges
• Highly proficient with version control using Git and experienced with collaborative development workflows
• Ability to mentor other developers, incorporate feedback, and collaborate effectively with senior developers, designers, product owners, and cross-functional partners

Preferred

• Knowledge of accessible UX best practices
• Experience with GitHub
• Experience with or knowledge of server-side rendered front-end applications
• Exposure to older JavaScript frameworks such as MooTools or jQuery
• Production experience with Amazon Web Services or Microsoft Azure
• Familiarity with server-side NodeJS or other languages like C#, PHP, or similar
