  • Commitment to writing clean and testable code and maintaining unit and integration tests
  • Enthusiasm for helping the team conduct effective code reviews and providing regular support to peers
  • Ability to break down complex problems into more manageable chunks
  • A focus on finding long-term solutions, ensuring that the product evolves in the right way
