- Write clean, reusable, maintainable and testable TypeScript/React code.
- Participate in code reviews and contribute to frontend engineering standards.

Important

This is a product engineering role focused on frontend and full-stack development, not simply a UI implementation role.

We are looking for a developer with strong fundamentals in React, TypeScript, frontend architecture, API integration, application state, usability, performance and software engineering practices.

The engineer may work across multiple products, modules, integrations and technology initiatives based on business and product requirements.

We value engineering fundamentals, ownership, problem-solving ability, code quality and willingness to learn more than experience in any particular business domain.
