UX Engineer Job Description Template

The UX engineer sits between design and engineering, building the front end implementation of design work and often owning the coded design system. The role exists because the gap between a design file and a working interface is where quality is usually lost, and someone fluent in both disciplines closes it far more effectively than a handover document.

Typical Duties and Responsibilities

• Implement design system components in code
• Build high fidelity prototypes for testing complex interactions
• Bridge design and engineering on feasibility and implementation detail
• Ensure implemented interfaces match the design intent
• Implement accessibility correctly at the component level
• Build tooling that connects design tokens to code
• Review front end implementation for design accuracy
• Contribute to design system documentation
• Prototype interactions that are difficult to convey in static design
• Advocate for implementation quality in both directions

Education

• Bachelor’s degree in computer science, design or equivalent experience

Required Skills and Experience

• 3+ years of front end development with strong design sensibility
• Expert HTML, CSS and JavaScript, and a modern framework
• Experience building and maintaining design systems in code
• Deep understanding of accessibility implementation
• Ability to work fluently with designers in their tools
• Attention to visual and interaction detail
• Experience with design tokens and theming
• Good communication across both disciplines

Preferred Qualifications

• Experience with animation and transition implementation
• Contributions to an open source design system
