About the vacancy

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).

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.
