  • Designing and implementing new features.
  • Writing documentation for users or maintainers.
  • Writing automated tests.
  • Learning new technologies.
  • Researching technologies for potential adoption.
  • Communicating clearly and efficiently around all of the above.
  • Collaborating productively with stakeholders and other engineers.
