Job Description

Principal React Engineer

Working in a business-facing, high-visibility environment, you'll collaborate closely with stakeholders and end users to evolve and refine an existing investment and research platform as needs change.

  • You'll take ownership of your work across the full software development life cycle, applying sound engineering practices and thoughtful design patterns along the way. 
  • You'll also enjoy sharing knowledge-coaching and supporting more junior engineers, and helping maintain high standards through collaboration and best practice.
  • You'll bring strong hands-on experience with React in an enterprise setting, including familiarity with the wider ecosystem of libraries and tools used for state management, data visualisation, testing, code quality, and build processes.
  • You'll be confident working with modern APIs such as REST, WebSockets, and GraphQL, and have a deep understanding of JavaScript fundamentals like scope, closures, and function binding.
  • Experience with cloud technologies such as AWS, AppSync, and CloudFront will be a plus, as will creative and analytical thinking when solving problems.
  • An eye for UX and design-whether sketching ideas, prototyping, or clearly communicating concepts-will help you work effectively with business stakeholders.
  • Familiarity with financial services or regulated environments is helpful but not essential; curiosity, ownership, and a desire to build great software matter most.
