About the role

Key responsibilities & impact

Own the end-to-end radiologist experience of Mosaic Reporting, developing a deep understanding of user experience and radiologist satisfaction as the product rolls out more broadly.
Design a system that adapts to the different ways radiologists have learned to interact with technology, rather than forcing a single workflow.
Balance innovation and familiarity: introduce new interactions while preserving enough of what radiologists already know to keep them confident and efficient.
Define how we prioritize next steps to improve radiologist satisfaction, identifying the signal in user feedback that should drive design decisions.
Contribute to product strategy and roadmap alongside the product lead, using insight into radiologist needs to help shape what we build and how we sequence it.
Plan and conduct user research (surveys, interviews, and usability studies with practicing radiologists) and synthesize findings into design direction.
Produce mockups, prototypes, and interaction flows in Figma, and partner with engineering to bring them to production.
Collaborate closely with radiologists and clinicians to understand what it takes to design Mosaic Reporting as a scalable product used by radiologists and patients around the world.
Create the standardized product manuals, documentation, and design language that will support customers across Radiology Partners and beyond.
Establish and own the design system and interaction patterns that keep the product consistent as it grows across surfaces, teams, and customers.
