At Visonum we develop software for measuring the quality of internet communication lines. This includes measuring the network throughput, packet loss, jitter, latency, and many other quality parameters. Our systems help internet providers build faster and more reliable infrastructure. Currently, our systems are being used by more than a million people.

We are enthusiastic about the functional programming paradigm, and use it to architect, develop and test our software. Immutable data, pure functions, explicit and controlled side effects are all part of our code. We usually start a new feature with a unit test and then follow with an implementation. Finally, we manage ourselves using the Agile SCRUM process.

We are always looking for new talents and value enthusiasm and self-initiative.
