- You’ll independently drive frontend projects from problem definition through rollout, working closely with designers, product engineers, and other Sail engineers

- Your work will range from reusable components, themes, and documentation to agentic tooling, automated quality checks, and modernizing the foundations of Stripe’s Dashboard

- Take end-to-end ownership of software projects, independently scoping problems and carrying solutions through design, implementation, testing, and rollout

- Build and maintain accessible, performant, and well-tested components, themes, and frontend APIs used across Stripe

- Build tooling, documentation, and automated quality checks that help engineers and AI coding agents use Sail effectively and meet Stripe’s UI quality bar

- Partner with product designers and engineers to understand their needs and turn recurring UI patterns into reusable design-system capabilities

- Help evolve the visual language of Stripe’s Dashboard while modernizing its underlying codebase and migrating legacy UI patterns

- Improve the accessibility, internationalization, observability, performance, reliability, and developer experience of the design system
