UX/UI Designer

This is a core user experience and user interface design position. You will work day-to-day alongside product managers, project leads and developers - developing user knowledge, identifying platform needs, and designing low-fidelity wireframes and high-fidelity mockups. You will review developed products for design accuracy and conduct user testing of new features.

You will own user experience as an area of practice within the team. That means being in the conversation early, pushing back when an idea goes against UX/UI best practices, and making human-centered design central to our product philosophy.

What You Will Be Doing

Conduct user research through interviews, surveys, and user testing to identify needs and pain points

Translate research findings into personas, user journeys, and experience maps

Design wireframes, mockups, and interactive prototypes at varying levels of fidelity

Build and maintain design systems and component libraries for consistency at scale

Deliver detailed design specs and assets for developer use

Collaborate with product managers and developers to align on requirements and technical feasibility

Ensure all designs meet accessibility standards (WCAG 2.1 AA and Section 508)

Review developer output for design consistency and user friendliness

Do you have experience in Wireframing?, An investigative mindset - the ability to independently examine, gather information, and synthesize findings about user needs and preferences

Strong design skills - as adept at typography, color, layout, and iconography as they are at determining interaction patterns, interface states, and managing platform design consistency

Experience with interface design tools such as Figma, Penpot, or Sketch expected

Accessibility credentials and coursework from the likes of IAAP and Deque University a major plus

Clear written communication - ability to draft documentation

Experience in a healthcare, clinical research, or academic software environment is a strong advantage
