Senior Product Designer – Mobile

InCommon is hiring on behalf of a US-based Series-B funded Healthcare Startup.

Role Overview

We are building a net-new, patient-facing mobile app and are looking for a senior product designer to lead the experience from zero to one. This is a foundational role where you will shape how patients interact with care, services, and health journeys through a mobile-first experience.

You will work at the intersection of product, engineering, and real users, owning early concept definition, UX architecture, and research-driven design decisions. This is not a polish-only UI role. The core of this job is problem framing, user understanding, and end-to-end experience design .

What Youll Work On

• Design the second mobile app in our ecosystem, this time patient-facing (the first app is provider-facing)
• Help define the product from early concepts to production-ready flows
• Contribute to a zero-to-one native mobile experience , built on a React Native stack
• Play a key role in shaping how in-house product and design capabilities are built

Key Responsibilities

• Lead end-to-end UX design for a patient-facing B2C mobile application
• Conduct and drive user research , including:
• Direct calls with patients for concept validation
• Usability testing and early prototype feedback
• Applying structured research methodologies to inform design decisions
• Design core user journeys, flows, and interaction patterns for complex, real-world healthcare scenarios
• Work closely with product, engineering, and clinical/operations stakeholders to translate needs into usable experiences
• Contribute to system-level thinking around mobile architecture, scalability of flows, and cross-feature consistency
• Leverage existing design system components while defining new patterns where needed
• Operate with high autonomy while collaborating cross-functionally

What Were Looking For

Must-Haves

• Strong experience designing B2C mobile apps
• Proven track record working on early-stage / zero-to-one products
• Deep strength in UX flows, information architecture, and interaction design
• Hands-on experience running user research (not just consuming research from others)
• Comfort speaking directly with users (patients) to test and refine concepts
• Ability to work independently and drive clarity in ambiguous problem spaces

Good to Have

• Healthcare or health-tech experience
• Experience designing for sensitive, high-trust user contexts
• Familiarity with React Native product environments
• Experience contributing to or working within design systems
