Principal Design System Designer

Opportunity

At Twin Health, we are on a mission to leverage the power of AI and advanced technology for the ultimate good: fundamentally transforming human health and well-being. To scale this monumental impact, we need a visionary Principal Design System Designer to write the visual and interactive DNA of our future.

This is not a maintenance role—this is a defining new era for our company, and you are arriving at the inflection point. Reporting directly to the Head of Design, you will lay the architectural bedrock that dictates how fast we move, how beautifully we build, and how deeply we impact lives for years to come.

We operate in a fast-paced, high-stakes environment where speed, execution, and responsible innovation are paramount. You won't just be managing a library; you will be making rapid decisions and putting them to work immediately. By building a world-class, future-proof design system, you will empower our entire product and engineering organization to deliver life-changing experiences to the people who need them most. Whether you are building from 0 to 1 or architecting a massive 1 to 10 revamp, you will take the lead in driving the strategy that powers our mission.

Responsibilities

• Architect the Company's Future: Play a critical role in defining the long-term trajectory of Twin Health's product design system. You aren't just building a system for today; you are creating the strategic blueprint that will support our next decade of growth.
• Speed & Bias for Action: In our fast-paced environment, you will drive rapid iteration and deployment, expertly balancing high-velocity execution with long-term architectural integrity.
• Establish System Governance: Define and maintain clear contribution models, documentation standards, and version control processes so the broader design team can easily adopt, contribute to, and scale the system at a rapid pace without creating fragmentation.
• Exceptional Execution & Craft: Uphold an uncompromisingly high bar for visual design. You know how to craft pixel-perfect components, define coherent design tokens, and create a cohesive visual language that scales beautifully across platforms.
