Position Overview
We’re looking for a Principal Product Designer with deep expertise in designing complex systems to join our team. You’ll focus on internal tools and operational workflows that power our prescription fulfillment process. These tools are mission-critical to PHIL’s business, and your work will directly impact efficiency, scalability, and quality of care.

This is a high-ownership role reporting to the Head of Design, ideal for someone who thrives in ambiguous problem spaces and can independently drive end-to-end design work—from shaping the vision to executing pixel-perfect experiences. You’ll need advanced interaction design skills, fluency in user research methods, and a strong grasp of systems thinking.

Responsibilities

• Own the user experience for internal-facing operational tools—mapping complex workflows and designing scalable, intuitive interactions.

• Independently lead end-to-end design work: from discovery, research, and ideation to wireframes, prototypes, and final specs.

• Conduct user research (e.g. interviews, contextual inquiry, usability testing) to inform and validate design decisions.

• Deliver high-fidelity interaction designs with thoughtful motion, behavior, and responsiveness across breakpoints.

• Collaborate closely with product, engineering, and operations stakeholders to deeply understand business goals and operational constraints.

• Facilitate workshops and feedback sessions to align cross-functional teams and generate ideas.

• Evolve and scale our internal design systems to support growing product complexity and consistency.

• Be a design thought partner across the organization—mentoring peers, advocating for design quality, and helping shape team culture.
  

Qualifications

• 8+ years of product design experience, with at least 3+ years operating at a principal, lead, or staff level.

• Proven track record designing complex tools or platforms, ideally for internal users in operational or logistics-heavy domains.

• Portfolio that demonstrates sophisticated interaction design, systems thinking, and research-informed decisions.

• Advanced user research capabilities, with experience planning and executing studies that drive product direction.

• Experience owning ambiguous problem spaces with minimal guidance and delivering business-critical impact.

• Deep understanding of interaction design principles, information architecture, and UX writing best practices.

• Expertise with Figma and modern prototyping tools; ability to communicate designs clearly with engineers and PMs.

• Strong communication and storytelling skills—you can clearly explain the "why" behind your design decisions to any audience.
  

Benefits

• Ground-floor opportunity with one of the fastest-growing health-tech startups

• Fully remote working environment

• Competitive compensation (commensurate with experience)

• Full benefits (medical, dental, vision)

• 401(k) contribution opportunity
