About the role

Key responsibilities & impact

Own the long-term technical direction of Roo's frontend platform, including the systems, tooling, and architecture that power development across web and mobile.
Partner with Product and Design to evolve our design system as a foundational platform rather than a standalone library.
Make our design system effortless to consume by engineers, designers, and AI agents through thoughtful integrations, documentation, tooling, and developer workflows.
Lead platform initiatives like framework upgrades, React Native modernization, Expo adoption, and shared library evolution.
Own the migration of legacy components to our v2 design system — including the tooling and documentation that let the rest of the team complete the migration themselves.
Establish patterns that let engineers ship new pages and flows quickly from a component library that's built for how people actually build in 2026.
Improve developer experience through shared tooling, automation, documentation, templates, and workflows that increase engineering velocity.
Identify and eliminate the friction points that slow builders down — missing tokens, undocumented patterns, inconsistencies that force one-off decisions — and fix them systematically.

Requirements

What you’ll need

Significant experience building production software, including a focus on frontend systems
Strong full-stack engineering fundamentals with deep expertise in React and TypeScript. You're equally comfortable building frontend experiences, backend services, developer tooling, and platform infrastructure when the problem calls for it.
React Native or mobile experience.
Experience working closely with designers and modern design systems. You're comfortable working in Figma and understand how design decisions translate into scalable frontend architecture.
Hands-on experience with AI-assisted development: Cursor, Claude, or similar. You're already building meaningfully faster with these tools, and you think about how to extend that leverage to everyone around you.
You've connected design systems to prototyping tools, AI coding environments, or engineering pipelines — and you understand what makes those integrations actually get adopted vs. ignored.
You operate well in an eng org — you understand how to get work prioritized, you don't need a PM to run interference, and you're comfortable owning a technical roadmap.
