Principal Design System Designer

Role Overview

• 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 exactly how design patterns impact the broader UX, ensuring that our system is as beautiful, accessible, and inclusive as it is functional. You can independently generate and land on a compelling visual direction from scratch.
• Drive & Measure Adoption: Partner with engineering and product leaders to champion system adoption across the organization. You will be responsible for metrics to measure the system's impact on product quality, engineering velocity, and overall user experience to ensure design translates to real-world results.
• Bridge Design, Code, & AI: Seize the chance to reinvent the bridge between our design and engineering teams. You will be empowered to forge entirely new operational flows, standing at the forefront of industry innovation by safely leveraging AI and Model Context Protocols (MCP) to automate and translate Figma environments directly into production code.
• Strategic Collaboration & Trade-offs: Be a relentlessly open and communicative partner. While you are highly autonomous in driving visual direction and moving quickly, you also know how to collaborate deeply, when to pull back, and how to make the necessary architectural trade-offs to keep cross-functional projects moving forward.
• Other duties as assigned

Requirements

• 8-10 years of experience as a system designer.
• Experience: A proven track record as a Principal Designer who has successfully built a 0–1 design system or led a massive overhaul of an existing one at scale within a top-tier, fast-paced tech environment.
• Visual & Systems Excellence: An outstanding portfolio that demonstrates exceptional execution and visual craft, inextricably linked with deep, scalable, and systematic thinking.
• Multi-Platform Architecture: Experience designing scalable systems that translate seamlessly across Web desktop, native iOS and Android, understanding the unique technical constraints and native interaction patterns of each.
• Deep Accessibility Expertise: Thorough knowledge of WCAG standards and a proven track record of baking accessibility and inclusive design principles into the core of a design system from day one—because building for the good of human beings means building for everyone.
• Rapid Prioritization & Decisiveness: The ability to navigate ambiguity, weigh complex architectural trade-offs quickly, and prioritize roadmap items that deliver the most immediate, scalable value to the broader team without slowing down momentum.
• Technical Fluency: Deep understanding of front-end constraints and modern tooling. You have developed seamless handoff flows with engineering and have hands-on experience using AI-driven design ops (like Figma MCP servers or AI IDEs) to tweak code, manage variables, and automate documentation directly.
• Mission-Driven Leadership: A history of proactively taking the lead on complex initiatives, making the team around you stronger, and guiding projects across the finish line with speed, low ego, and a passion for building technology that genuinely helps people.
