  • “Set the tone” in terms of craftsmanship standards and code quality
  • Active/thoughtful participation in discussion surrounding ticket specification, design review, etc.
  • Participate in active, intentional, and thorough code reviews.

Requirements

  • 5+ years of experience building production React applications
  • 1 year of TypeScript experience
  • Minimum 3 years working with any strongly typed programming language
  • Very strong verbal and written communication skills.
  • Very strong understanding of idiomatic UI implementation patterns
