• Tackle complex challenges at the intersection of AI, healthcare, and human experience

The Role

We’re looking for a Principal Product Designer (Head of Design) to define and build our design function from the ground up. This is a pivotal, high-impact role at a critical moment in Limbic’s journey as we transition from a B2B platform to a consumer-facing product. You will lead the design of experiences used by patients in vulnerable moments, where trust, safety, and emotional nuance are essential. You’ll own the end-to-end patient experience, shape our product and brand, and establish design as a strategic capability across the company. This is a highly visible role, working closely with our CEO, CTO, and cross-functional leadership across product, machine learning, and clinical teams.

What You’ll Do

• Own and build the design function from 0 → 1, setting standards, processes, and culture
• Lead product design across the entire patient journey, from onboarding to ongoing care
• Design experiences that are clinically safe, emotionally intelligent, and effective
• Shape Limbic’s product, brand, and experience in parallel
• Partner closely with product, ML, clinical, and growth teams to deliver high-impact outcomes
• Translate complex AI and clinical systems into clear, intuitive user experiences
• Establish a high bar for craft, including interaction design, motion, and visual quality
• Use research, data, and insight to drive measurable improvements in patient outcomes
• Contribute to company strategy, not just design execution
