Back-end Software Engineer (Java) job in Warsaw / remotely

Back-end Software Engineer (Java)

Project - the aim you'll have

Our clients are the largest mobile network operators in Poland and in Europe. We deliver solutions and services that transform their networks and provide innovative services to millions of subscribers.

The goal of the project is to build a new, modern, end-user portal for managing the configuration of voice services for business customers of one of the leading mobile operators. The portal is being built using Angular, Java, Docker and Kubernetes.

Position - how you'll contribute

You will join a team of software developers working on implementing new functionalities  for mobile operators.

You will work closely with other teams including DevOps and QA and you will also participate in sprint reviews with the client.

We focus on autonomy; we will not force you to  performing a task a certain ways – you decide, and you are responsible at each every stage of the Software Development Life Cycle.

We play as a team and we expect the same from you – group brainstorming, quick code review, rubber duck debugging, or a short pair programming session are tools that are regularly used by every member of our team.

  • Experience with ELK (Elasticsearch, Kibana, Beats & Logstash)
  • Experience with Agile methodology
