Founding Product Designer

About The Role

This is a first-ever design hire at a seed-stage neurotechnology startup building a cognitive fitness tracker — think of it as Strava for the brain. The product surfaces trends and insights on mental clarity, cognitive load, stress, and more, with a mission to make brain health accessible, measurable, and actionable. There is no design system to inherit, no style guide to reference, and no established design language for this ambient product category — because nothing quite like it exists yet. You'll build everything from the ground up, working directly with the Founder to own the full design surface from early concept through shipped product. We're looking for a bit of a mad artist: someone who takes risks, challenges conventions, brings a multidisciplinary perspective, stays deeply curious, and pushes back when something feels wrong.

What You'll Do

• Rapidly generate and iterate on design directions, testing ideas with early users to drive engagement
• Build and maintain the company's design system entirely from scratch
• Lead user research to surface unmet needs and validate product hypotheses
• Collaborate closely with engineers to ship implementable, high-quality interfaces
• Define the visual and interaction language for a voice-first, ambient product category
• Partner with the Founder on product strategy — shaping what gets built, not just how it looks

Requirements

• 2+ years of design experience at an early-stage consumer startup
• Proven track record shipping full-scale consumer apps end-to-end — from concept to production, not just components or marketing sites
• Experience building and maintaining a design system (not just handing off Figma files)
• Authorized to work in the United States without visa sponsorship
• Proficiency with Figma and strong design systems tooling
• Hands-on experience with user research and rapid prototyping to validate hypotheses
• Product thinker first — you shape what gets built, not just how it looks
• Comfortable working directly with a founder and influencing product direction
• Core contributor to a team that built something people genuinely love from the ground up

Nice to haves

• Experience with voice-first, ambient, or AI-assisted product design
• Background in consumer health, fitness, wearables, or related domains

Compensation & Benefits

• Salary: $150,000 – $200,000 USD annually
• Meaningful equity package
• Health benefits
• Flexible PTO
