Hello Heart is on a mission to make heart attacks a thing of the past.

We’re an AI company focused exclusively on heart health, building a platform that predicts and prevents cardiac events before they happen—identifying risk up to 10 days in advance versus 10 years in traditional clinical models. 

This is already working at scale. Hello Heart has been shown to reduce inpatient hospital days by 47% and deliver ~$1,800 in annual savings per member. Hello Heart is the cardiac prevention partner to over 80% of large U.S. health plans and serves hundreds of public and private employers.

We’re defining how the #1 cause of death—heart disease—is managed in the AI era. Join us.

• Own the design system end-to-end: visual language (typography, color, iconography), component architecture, interaction patterns, documentation, and contribution model.
• Build and maintain design-to-code pipelines that reduce friction between design and engineering, automate repetitive workflows, and let components ship with higher fidelity and less overhead.
• Conduct ongoing UI & Design System audits across live mobile products to identify UI debt, visual inconsistencies, and opportunities to elevate the overall quality.
• Champion accessibility and inclusive design across every component and pattern, from contrast ratios to assistive technology behavior.
• Lead cross-functional design initiatives beyond the system, including product experience work on IA, navigation, and core product strategy.
• Partner closely with engineering, product, and brand to drive system adoption, resolve cross-team pattern conflicts, prioritize initiatives, and ensure technical feasibility and component quality in production.
• Evangelize and scale the design system: present direction, establish rituals/processes, facilitate contribution, and build the culture and team enablement that keeps it alive as the product scales.

• 8+ years in product design, interaction design, information architecture, or systems design, with deep experience launching native mobile products (iOS and Android).
• A strong portfolio that demonstrates design systems you built, maintained, or significantly elevated, with clear evidence of impact at scale.
• Hands-on AI fluency: you've used AI tools/agents to automate workflows, accelerate documentation, build design-to-code pipelines, or generate production-ready components—not just for quick Figma work.
• Strong product design range & systems strategy: you can lead IA and experience strategy work on complex initiatives while connecting day-to-day decisions to broader system strategy.
• Practical accessibility mastery: WCAG, contrast, assistive technology patterns, inclusive design, applied in real shipped products.
• Sharp communication and cross-functional instincts: highly organized, strong alignment skills across engineering, product, and brand, with high standards for thorough and maintained documentation.
