What you'll be doing

  • Leverage a strong CS foundation to design and implement performant algorithms for a variety of applications such as graph traversal, among others.
  • Build, test, and ship modern customer-facing features and frontend software products using React, TypeScript, Redux, React-Query, JSS tools like Styled-Components, and other industry-standard libraries. Champion best practices across our frontend product and promote high-quality code across our teams.
