Embedded Software Engineer, Communications Services

DataArt
IT - разработка ПО

    Our client is a global provider of testing, analytics, and security solutions for the telecommunications sector.

     

    DataArt's specialists are helping to develop an analytical solution which tracks transactions that determine the quality of customer experience with network service providers (QoE). From these transactions, key indicators are displayed, such as radio frequency performance, base signal speed, and service performance (VoLTE, SMS). All metrics are combined into the final QoE estimates, which are used to determine hot spots and help localize and solve service quality problems.

     

    The main responsibilities are designing, implementing, and verifying new features in the test agent embedded software products of the client's solution. These software products need to operate with real-time performance in various container and virtual machine environments, and they fit into the client's architecture via REST APIs.

     

    The project uses Jenkins for Continuous Integration, Jira for issue tracking, and Git for source control.
