Comcast Corporation

Software Engineer(JavaScript, HTML), Player Platform - VIPER





Denver, Colorado, United States

Comcast’s Technology, Product & Experience organization works at the intersection of media and technology. Our innovative teams are continually developing and delivering products that transform the customer experience. From creating apps like TVGo to new features such as the Talking Guide on the X1 platform, we work every day to make a positive impact through innovation in the pursuit of building amazing products that are enjoyable, easy to use and accessible across all platforms. The team also develops and supports our evolving network architecture, including next-generation consumer systems and technologies, infrastructure and engineering, network integration and management tools, and technical standards. We offer a flexible working environment to balance the need to work independently wherever you choose, with days that require collaboration at one of our offices. Our roles primarily reside inside or around one of our Tech Hubs (Philadelphia and surrounding suburbs, Denver, Austin, Silicon Valley, Washington DC/N. Virginia). Some roles can work virtual full-time if they are not near a Tech Hub, but that is dependent upon the needs of the position and amount of collaboration required.

Job Summary

As a Software Engineer on the JavaScript Player-Platform team, you will develop client-side libraries that are used by millions of people to stream Live, On-Demand, and Recorded content on desktop web browsers, casting-enabled devices, and dozens of Smart TVs and Set-Top Boxes.

Job Description
