Principal Product Designer

Radiology Partners is the largest radiology practice in the U.S., and they are seeking a Principal Product Designer for their AI business unit, Cognita. In this role, you will own the radiologist experience for a groundbreaking radiology reporting product, shaping its design and product strategy while ensuring user satisfaction.

Responsibilities:

• 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
• Mastery of Figma and modern prototyping tools, with a portfolio that demonstrates both craft and systems thinking
• Fluency in interaction and visual design, information architecture, and design systems
• The judgment to balance ambitious, novel interactions against the familiarity and reliability that expert users depend on
• Comfort operating in a fast-moving, ambiguous environment and owning the design of a product end-to-end
• Strong written and verbal communication, with the ability to articulate design rationale to engineers, clinicians, and leadership
• Strong ownership mindset and good product judgment
• Up to 20% travel or more as needed
• Performs other duties as assigned

• Experience designing for clinical, medical, or other expert and high-stakes professional users
• Experience designing real-time, low-latency, or voice- and dictation-driven interfaces
• Familiarity with LLM- or AI-powered products and designing for probabilistic, model-driven outputs
• Experience working in healthcare or other regulated environments, and handling PHI / building to HIPAA requirements
• Radiology or medical imaging domain knowledge (modalities, reporting workflows, structured reporting)
• Experience building and maintaining design systems and product documentation at scale across global customers
• Familiarity with React / Next.js and close, hands-on collaboration with frontend engineers
