You will work on our dashboard’s front-end and coordinate with UX/UI designers on priorities of the dashboard work. The front-end is mainly written in React and uses RxJS. You will be involved in building APIs, components to pull and display call data.

  • You are proficient with Redux, RxJS or other similar data flow frameworks. The data flow in our dashboard is similar to Facebook’s Flux.
  • You have a deep understanding of closures, DOM manipulation, HTTP, WebSockets, and cross browser compatibility challenges.
  • You have experience working with modern Javascript toolchains (Webpack, Babel, Grunt, less, etc.).
  • You have demonstrated skill and enthusiasm for learning, and applying new technologies when appropriate.
  • You have experience coordinating software development teams.
  • You have experience working together with designers in a user-centered manner.
  • A minimum three years of experience.
  • Fluency in spoken and written English.

  • Friday demo: Every week you get to show-off your contributions and get immediate feedback.
  • Great team: Our team is sharp, eccentric, loyal, and ambitious.
