Playwire seeks an experienced JavaScript developer to lead the ongoing development and enhancement of our client-side advertising technologies. We seek people who are disciplined but also creative, and unafraid to jump into projects that will be seen and used by millions of people. Serious applicants should have experience doing more than just converting mockups into working pages: you should understand what it means to develop a complicated application or widget using JavaScript.

You'll immediately be an important member of a development team with a wide variety of responsibilities and opportunities, including primary responsibility for the architecture of our client-side adtech.

  • Deep knowledge of browser capabilities
  • Experience with the use of modular JavaScript, using technologies such as RequireJS.
  • Knowledge of unit testing methodologies, particularly as applied to JavaScript development.
  • Experience working with APIs, either integrating a third-party API or creating your own when necessary.
  • Experience with HTML5 and CSS3.
  • Experience with responsive design and cross-platform scripting for desktop/mobile.
  • An understanding of source control, particularly git and Github.
  • Experience working in a team using Agile development and project management practices.


  • Experience benchmarking client-side Javascript.
  • Awareness of JavaScript trends and a forward-looking approach to the language and its capabilities.
  • Experience with JavaScript designed to be embedded in third-party Web pages.
  • Experience with advertising units, terminology and standards, such as VAST and VPAID.
