Principal Software Engineer, Xfinity Home Camera Platform at Comcast (Washington, DC)

Comcast's Technology & Product 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.

The Xfinity Home Camera Platform is being developed by Comcast Cable's Technology & Product (T&P) organization and consists of advanced technologies that process home automation and security video to provide added value to these products. Advanced video analytics algorithms running both on the camera and in the cloud will enable the delivery of useful notifications and easy to consume digests of video security content. This can include thumbnails or short clips where people are present in the video and could be as advanced as recognition of household members, pets, vehicles, etc. and their behaviors.

As a Principal Engineer, you will be a technical leader on the team with significant input on technical design decisions. You will work with other engineers and researchers with backgrounds in advanced fields such as computer vision and machine learning (including deep learning). As a key member of the team, you will help define, refine, and test state of the art algorithms, and scale the associated systems for high performance, stability, and availability.

Comcast T&P encourages career development with regular opportunities for training and programs for innovative cross-team projects such as week-long Hackathon and job rotation programs over the summer.
