About the Role

We are seeking a highly experienced Senior UX/UI Developer who combines strong visual design skills with hands-on front-end development expertise to build next-generation, AI-enabled applications.

This is a hybrid design-and-build role for someone who can translate complex product requirements into intuitive, polished user experiences and implement those designs using production-ready front-end code.

You will help design and develop AI-powered legal technology applications, including interfaces for document review, source-linked findings, high-density data tables, approval workflows, and document management.

The technology stack emphasizes lightweight, server-rendered web applications built with HTML, Tailwind CSS, vanilla JavaScript, and modern hypermedia frameworks such as HTMX or Datastar.

This role is ideal for a senior professional who enjoys both designing exceptional user interfaces and building them from the ground up.

• Build reusable UI components, interaction patterns, and shared component libraries.
• Design workflows for AI-generated findings, source citations, document review, approval checkpoints, and long-running processes.
• Maintain consistent design systems and visual standards across multiple applications.
• Collaborate closely with product managers, software engineers, and other stakeholders.
• Integrate front-end code into existing applications while following established Git, code review, and CI/CD practices.
• Ensure accessibility, usability, cross-browser compatibility, and responsive design.
• Optimize interfaces for performance, maintainability, and scalability.

Required Qualifications

• Extensive professional experience in both UI/UX design and hands-on front-end development.
• Strong proficiency in HTML5, Tailwind CSS, and vanilla JavaScript.
• Demonstrated experience designing and delivering production-ready web applications.
• Experience developing interfaces for server-rendered web applications and template-based component systems.
• Strong understanding of responsive design, accessibility standards, usability principles, and interaction design.
• Experience creating reusable components, design systems, and style guides.
• Proficiency with Git, code review workflows, and CI/CD pipelines.
• Excellent collaboration and communication skills.
• A portfolio demonstrating both design expertise and practical front-end implementation.
• Ability to work full-time from day one.

Preferred Qualifications

• Experience with AI-enabled applications, generative AI products, or LLM-powered workflows.
• Familiarity with HTMX, Datastar, or other hypermedia and server-driven UI frameworks.
• Experience with server-sent events and reactive user interfaces.
• Familiarity with Azure DevOps and automated deployment workflows.
• Experience with front-end testing, WCAG accessibility validation, and cross-browser debugging.
