Responsibilities Carefully implement critical UI components, shared functionality, and certain subsystems (like monitoring, testing, validation, etc) Rapidly implement functional UI elements from design mocks and workflow diagrams, with an eye toward correctness and readability. “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.
