About The Position

Cala Health is seeking a UI/UX Designer to own the design of Cala’s digital experiences, including web and mobile. This role will champion the creative vision and manage end-to-end visual and interaction design. The designer will collaborate closely with Product and Engineering teams to establish a cohesive design language across all platforms, translate requirements into user experience flows, and maintain related design documentation.

Requirements

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.

Nice To Haves

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.

Responsibilities

Own end-to-end design execution, including 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 transform complex data into actionable insights.
Create Cala’s visual and interaction design language and the system behind it, including a component library, design tokens, and versioning, to ensure scalability across form factors and accessibility modes, mapping directly to front-end implementation.
Conduct Voice of Customer (VOC) research, interviews, and usability testing with Product Management for early-stage discovery and post-design acceptance testing.
Partner with product and engineering to translate 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.
