UI/UX Designer

Summary

Cala Health develops non-invasive prescription therapies to help people manage chronic diseases. The UI/UX Designer will own the end-to-end visual and interaction design of Cala’s web and mobile digital experiences, including user flows, design systems, data visualizations, research validation, documentation, and collaboration with Product and Engineering in a regulated medical device environment.

Responsibilities

• Own visual design and user experience flows across web and mobile (iOS/Android) — from flows and wireframes through high-fidelity UI, interaction, and motion design — meeting accessibility standards (e.g., WCAG) throughout
• Design flows, dashboards, and data displays that turn complex data into actionable insights
• Create Cala’s visual and interaction design language and the system behind it — component library, design tokens, versioning — so it scales across form factors and accessibility modes and maps directly to front-end implementation
• With Product Management, conduct Voice of Customer (VOC) research, interviews, and usability testing for early-stage discovery and post-design acceptance testing
• Partner with product and engineering to turn concepts into high-fidelity design documents, including notification and feedback moments across connected devices
• Author and maintain UI/UX documentation, redlines, and specifications with rigorous version control for handoff to engineering
• Lead cross-functional design reviews from concept through implementation, and scale design operations to support Cala’s growth in a regulated medical device environment

Skills

• Bachelor's degree in Graphic Design, Human-Computer Interaction (HCI), Interaction Design, related disciplines, or equivalent practical experience
• 3+ years of digital UI/UX or product design experience with shipped web and mobile products, including healthcare platforms for patients and/or clinicians within HIPAA regulations and data privacy/Protected Health Information (PHI) constraints
• Deep understanding of native mobile design standards, including Apple Human Interface Guidelines (HIG) and Google Material Design
• Deep knowledge of accessibility standards (e.g., WCAG) and inclusive design, and direct experience developing accessibility-driven user interfaces
• Familiarity with medical device usability engineering standards (IEC 62366, FDA Human Factors guidance) and comfort with the documentation and version-control rigor a regulated environment requires
• Experience in Agile/Scrum environments, partnering closely with Product, Engineering, and QA
• A portfolio showing strong visual design sensibility and end-to-end UX work across connected platforms
• Proficiency in Figma, including components, auto layout, variables and modes, Dev Mode, prototypes, and design documentation practices
• Hands-on with AI-assisted design tooling for concept exploration, research synthesis, and prototyping, with sound judgment about its limits in a regulated context
• Proficiency in usability testing to validate design decisions
• Experience creating and scaling a design language or design system, including design tokens, plus enough front-end literacy (HTML/CSS, React or SwiftUI) to collaborate on feasibility
• Applicants must be authorized to work in the United States on a full-time basis, or eligible for work authorization through a sponsorship path that Cala Health is able to support
• Experience designing for wearable or embedded device displays
• Experience participating in Formative and Summative Usability Testing specifically for FDA submissions or CE marking
• Experience designing AI/ML-enabled or adaptive software in FDA-regulated products
• Comfort building interactive prototypes in code or with AI prototyping tools before handoff
