Senior Software Engineer

Many millions of users depend on Skype, Skype for Business and now Teams for every day instant messaging, conferencing, app sharing and more. In the Skype Infrastructure team, we are building a massively scalable, highly reliable, geo-redundant system that allows users and administrators to easily manage the system. This information must be available for many other services to consume at very high rates and with very low latency. It also allows the internal engineering teams to change the behavior of their services, manage controlled rollouts and conduct experiments.
