  • Ability to write well-documented, clean Javascript code

  • Experience with automated testing suites, like Jest or Mocha
  • Proficient understanding of code versioning tools, such as Git
  • Familiarity with continuous integration
  • Experience working with Swift, Objective C, and Java a plus but not required
