Brief description of the company

Our Bratislava-based company FREQUENTIS Solutions & Services belongs to the Austrian group FREQUENIS AG (www.frequentis.com), specialized in safety-critical voice communications, for example for air traffic control towers, public safety control rooms (112) or air defense forces. Our mission critical solutions cover diverse areas, such as telephony and radio communication, Geographical Information Systems (GIS), incident and resource management, video surveillance and automatic video analytics.

In the last couple of years this business has evolved from hardware- to software-centric solutions and Frequentis has also increasingly provided mission-critical IT solutions beyond voice communication to our customers. We follow the Scrum methodology and our applications are mostly developed in Java to the highest quality standards.
From an engineering perspective we deploy state-of-the-art technologies and design patterns. Our solutions use JAVA and Microsoft .NET foundations, distributed architectures, low-latency telecommunications processing, real time web applications, integration platforms and high availability. Each of our solutions contains their own unique and challenging problems to solve.

For our customers, lives may be at stake and seconds count. Our products thus need to be developed to the highest standards when it comes to usability and reliability. Safety is what guides us from the first designs till the final tests of any of our product. If those are the kinds of challenges that excite you, then you have come to the right place!
