UI/UX Engineer

Faex Health is hiring a UI/UX Engineer to design and build user experiences inside a Django application. This hybrid role is based in Greenwood Vlg, CO, and includes leading the Faex design system on Bootstrap 5 while improving key product journeys across iPhone, Android, and the web.

Role Overview

You will take ownership of interface and interaction design while partnering with developers to implement reusable front-end components. The work spans the redesign of the product’s path from sign-up to the first scan, mobile-first experience details for wrapped web apps, and clinician-facing workflows such as dashboards and tracking tools.

Responsibilities

• Own design as the product redesign continues on a new Bootstrap 5 foundation, defining layout, navigation, typography, color, and components.
• Own design and the front-end component library; developers implement by connecting components to application logic and data.
• Translate research findings and product goals into user flows, wireframes, prototypes, and high-fidelity designs.
• Write clean, responsive, and accessible HTML, CSS, and JavaScript in Django templates, using Bootstrap 5 and a shared component library.
• Create and maintain a Faex design system with reusable components, tokens, and usage guidelines for consistent developer adoption.
• Design for mobile apps that wrap the web app so screens feel native on iPhone and Android, including touch targets, gestures, and photo-upload flows.
• Make complex health information clear and calm for scan results, scores, trends over time, and Felix conversations, without overstating what results mean.
• Design the clinician-facing Faex MD dashboard, including improvements to live experiences such as the GLP-1 gut-health journey and period tracker, plus new products such as Faex Infant and partner onboarding.
• Meet WCAG accessibility standards and ensure screens work in all 13 languages, including right-to-left Arabic and CJK scripts such as Japanese, Chinese, and Hindi.
• Run usability tests, review analytics on drop-off points, and improve the path from sign-up to first scan.
• Work in the Git workflow using Azure Repos and Azure Boards, review front-end changes, and collaborate with developers on implementation.

Requirements

• 5+ years designing digital products, including at least 3 years writing production front-end code.
• Expert HTML and CSS, including responsive layouts and cross-browser testing using Flexbox and Grid.
• Strong Bootstrap experience, ideally Bootstrap 5.
• Working JavaScript skills for interactive components and front-end behavior.
• Proficiency in a modern design and prototyping tool such as Figma.
• Experience building or maintaining a design system or component library.
• Experience designing and building multilingual interfaces, including RTL layouts and CJK text.
• Solid knowledge of accessibility standards (WCAG) and mobile-first design.
• Comfort working with Git and collaborating in a shared codebase with developers.
• A portfolio that demonstrates both design work and front-end code you wrote.
• Comfort working day to day with AI coding assistants such as Claude Code and Kiro, with the ability to pick up new tools as they change.
• Ability to work in the Denver office three days per week.

Preferred Qualifications

• Familiarity with the Faex app, or experience designing health, wellness, or medical products.
• Experience with Django templates or other server-rendered web frameworks.
• Experience designing data visualizations, dashboards, or clinical interfaces.
• Experience with web apps delivered inside native mobile wrappers.
• Experience with user research, usability testing, and product analytics.
