The Role
Make your mark at Comcast -- a Fortune 30 global media and technology company. From the connectivity and platforms we provide, to the content and experiences we create, we reach hundreds of millions of customers, viewers, and guests worldwide. Become part of our award-winning technology team that turns big ideas into cutting-edge products, platforms, and solutions that our customers love.

You’ll do the best work of your career right here at Comcast. (In most cases, Comcast prefers to have employees on-site collaborating unless the team has been designated as virtual due to the nature of their work.

Job Summary

This position will be with the OTTV team where we implement configurations for third party applications to operate on all of the various Comcast ecosystems and set top boxes. Our duties include certifying third party apps prior to being deployed to production and working closely with the product team to resolve any issues we find during that process. We also implement the code which allows the apps to then be used by our customers. We then track the app in production to ensure that it continues to perform as desired. Since we do not control the code of these apps directly, this means we need to adapt quickly and effectively to any changes that third party app partners might make to their app.
