Take part in the development of audio and video conferencing services. Engage in the design, development and support of servers written in Java. Write efficient and thread-safe code for an application that runs under heavy load. Design the system so that the failure of several servers does not affect the availability of the service. Participate in code-review, help colleagues with the development. Provide hot update service version without down time. Work with distributed systems such as GridGain. Write functional and modular auto tests.
Our team is developing a new generation of video conferencing services built using WebRTC, the video quality of which is adapted to various networks: 3G, WiFi, LTE. It allows you to make video calls and organize video conferences for hundreds of participants. Users can connect to the service from browsers, from smartphones and using desktop applications.
Now we are looking for strong developers in the new project team, which started less than two years ago. There is almost no legacy in this project, and it is possible to choose new interesting technologies, since most of the components you have to develop from scratch.
