The Problems You’ll Solve

At Carta, our employees set out on a mission to unlock the power of equity ownership for more people in more places. We believe that the problems we solve today unlock the opportunities of tomorrow.

• Architect and evolve the Ink component library: Build and maintain robust, production‑ready React components that blend rigorous design system standards, intuitive developer ergonomics, and extensible API design.
• Redefine the Design System for the Agentic Age: Lead the R&D on how our design system evolves to support AI‑driven interfaces, updating our definition of a design system to accommodate generative workflows, ensuring Ink is optimized for both human developers and AI agents.
• Bridge the gap between design and code: Act as a technical translator, taking concepts from Figma and turning them into performant UI code, ensuring that the polish of the design is never lost in translation.
• Elevate frontend quality and developer velocity: Drive cross‑functional projects to improve animation fluidity, CSS architecture, and system modularity, helping product teams solve 80% of their UI problems instantly so they can focus on the unique 20%.
• Coach and advocate for system adoption: Mentor engineers and designers across the organization, conducting code reviews and design reviews to ensure best practices are met, while gathering feedback to iteratively improve the system’s flexibility and ease of use.

Team You’ll Work With

You’ll be joining our Design System team Ink. Ink is where visual design, user experience best practices, and modern React architecture fuse together to create a beautiful set of tools that allow teams to create great products fast. Our ultimate purpose is to enable excellent design at scale, building foundational components, tooling, and documentation that empower hundreds of Carta engineers and designers to ship consistent, high‑quality, and accessible interfaces.

About You

• Systematic Thinker: Track record of replacing custom, one‑off UI with modular, reusable solutions, articulating trade‑offs of API design decisions to engineers and designers.
• React & CSS Expert: Deep knowledge of React (modern patterns, hooks, context), CSS (architecture, scalability), and animation technologies such as CSS Animations, Framer, and D3. Write code that is functional and a joy for other developers to use.
• Design Fluent: Comfortable working inside Figma, understanding interaction design nuances, and prototyping complex UI behaviors to validate concepts before production.
