  • Refactor legacy or complex areas of the codebase to improve readability, testability, and long-term health.
  • Identify and fix issues across the stack, ensuring solutions are robust and scalable.
  • Collaborate closely with product managers, designers, and other engineers to define requirements, refine stories, and deliver predictable outcomes.
  • Provide thoughtful code reviews, offer technical guidance to less experienced engineers, and contribute to a culture of continuous improvement.
  • Help shape the technical direction of the team through practical suggestions, hands-on implementation, and identifying opportunities to reduce friction or complexity.
  • Contribute to improving our front-end developer experience, including building tools, testing practices, and performance optimisations.
  • Ensure technical decisions support our goals of quality, performance, reliability, and security.
  • Work with and contribute to open source codebases, including evaluating, extending, and maintaining shared libraries and tools where appropriate.
Who You Are

  • Education: Preferred Minimum Bachelor's degree in CS, EE, SW, CE, MIS; or equivalent experience.
  • You write maintainable, well-tested code and care about leaving things better than you found them.

  • You take ownership of outcomes, follow through on commitments, and hold yourself to a high standard of reliability.
  • You enjoy mentoring and supporting others, and you contribute positively to the team’s culture and technical growth.
  • You stay up to date with modern tools and approaches without being dogmatic. Your goal is to find the right solution, not the trendiest one.
