Java/Kotlin Developer


We are building a Software House aware of its capabilities and focused on intelligent development of both the organization and people who create it. We focus on the independence of the team in the selection of technologies, approaches to architecture and negotiation of these points directly with the client. We promote an agile approach and we believe that chemistry and common understanding of goals are the most important in contact with the client.

For our Norwegian Client that operates in Energy and Green Tech sectors, we are building DEV team that operates mainly in JVM tech stack. Main programming language is Kotlin and what is more important, we are not talking here about Android App development but advanced Backend systems based on Google Cloud Platform. If you don’t know Kotlin, it’s OK, we can teach you “on the go”.

The platform that we develop with our Norwegian Partner supports large data sets coming from distributed IoT systems around the world. We are also adding extra layers for Monitoring, Data Analytics, Data Handling and Security purposes. It’s NOT a “Body Leasing like” project, but we do take responsibilities for separate modules and also work hand in hand on various Custom projects for End Clients that come from Kuwait, Singapur, Taiwan, Germany, Norway and UK. Other technologies that appear are: GCP, ELK, Akka, Spring Boot, Kafka and other modern stuff.

The team spirit between both companies is very open and easy going. Random trips to Oslo might happen, but only if you want to.
