Job Description

Faex Health is building clearer, calmer experiences for sensitive health information, and the UI/UX Engineer role sits at the intersection of design leadership and front-end implementation. This position will shape user journeys inside a Django application while partnering closely with the CTO and developers to deliver consistent experiences across iPhone, Android, and the web.

Working in a hybrid setup from Greenwood Vlg, CO, you will lead the design system on Bootstrap 5, redesign the path from sign-up to first scan, and help make complex clinical content easier to understand.

Responsibilities

Own the design for a continuing redesign on a new Bootstrap 5 foundation, guiding layout, navigation, typography, color, and components.
Own the design and front-end component library; developers handle implementation by connecting your components to application logic and data.
Translate research and product goals into user flows, wireframes, prototypes, and high-fidelity designs.
Write clean, responsive, accessible HTML, CSS, and JavaScript in Django templates, using Bootstrap 5 and a shared component library.
Create and maintain the Faex design system, including reusable components, tokens, and usage guidelines for consistent developer application.
Design for mobile app experiences that wrap the web app, aiming for native-feeling iPhone and Android interactions, including touch targets, gestures, and photo-upload flows.
Help make health information clearer and more measured across scan results, scores, trends over time, and Felix conversations, without overstating what results mean.
Design the clinician-facing Faex MD dashboard, improve live experiences including the GLP-1 gut-health journey and period tracker, and design new products such as Faex Infant and partner onboarding.
Ensure every screen meets WCAG accessibility standards and supports all 13 languages, including right-to-left Arabic and CJK scripts (Chinese, Japanese, and Hindi).
Run usability tests, analyze where users drop off using analytics, and improve the path from sign-up to first scan.
Work in a Git workflow with Azure Repos and Azure Boards, review front-end changes, and collaborate with developers on implementation.

Requirements

5+ years designing digital products, with at least 3 years writing production front-end code.
Expert HTML and CSS, including responsive layouts, Flexbox, Grid, and cross-browser testing.
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 (Chinese, Japanese, Korean).
Solid knowledge of accessibility standards (WCAG) and mobile-first design.
Comfort working with Git alongside developers in a shared codebase.
A portfolio showing both your design work and the front-end code you wrote.
Comfort working day to day with AI coding assistants such as Claude Code and Kiro, and the ability to pick up new tools as they evolve.
Ability to work in the Denver office three days per week.
