As you develop your career, you will apply statistics, machine learning, and other data science techniques to obtain valuable insights that may not be immediately obvious.

You will interact with systems capable of processing billions of events per day, providing both a real time and historical view into the operation of our video-over-IP systems. Optimize metrics gathering and reporting for performance, using the best tool for the job. Work with open source and vendor-provided analytics and visualization tools.

Monitor data for quality to ensure that our platform remains the best possible source of data for use in making business decisions. Work with data providers to identify, troubleshoot, and resolve sources of data inaccuracy.
