Online interview

What would you do with us?


Unified Management Platform (UMP) is a flagship product of AVSystem targeted for telecoms. It allows them to automatically setup, upgrade and monitor all of their routers and other network devices. It’s a multi-protocol, multi-server, heavy-duty back-end with GUI designed for Customer Care departments.
We are looking for a full-stack software engineer to join one of our three cross-functional UMP R&D teams. We expect you to be open to lots of cooperation on all product aspects — back-end, front-end, data-science, devops and testing — all of these are on the menu. We code using Scala and Java, but we are looking for strong candidates from any technology background.

Scope of daily responsibilities and tasks


  • Development: cross-cutting tasks from typical back-end protocol / security / database-related tasks to application code and GUI
    • writing code and unit tests in Scala and Java,
    • reviewing the code of teammates,
    • cooperation with QA Engineers, UX Designer and Product Owner in the team
  • Occasional cooperation with:
    • Data-science team for functionalities using AI / ML
    • Technical Project Manager who is a task stakeholder / client proxy
    • Site Reliability Team as a second line of support during the working day
    • Whole Scrum Team during daily 15min stand-up and a total of 4h of Scrum meetings during one-week sprints

The technologies we use


Scala, Java 8, MongoDB, Redis, Kafka, Spring, Vaadin, ScalaJS, JGroups, and Docker, Kubernetes and Jenkins in the infrastructure part.
As for testing  — apart from code review, a great deal of automated unit tests, Selenium and Gatling stress tests. In addition, QA Engineers within the team do manual tests and manual regression tests every two months before each new release.

Who we are looking for


  • Quick learner who is great at collaborating with others and willing to code full-stack tasks in Scala and Java — we are looking for strong candidates from any technology background
  • … who has at least 2 years of commercial experience and a higher IT education 
  • … who has an understanding of
    • network protocols: IP, TCP, UDP, HTTP(S), FTP, SSH, Telnet
    • databases (NoSQL is a plus), system design, object-oriented programming, algorithms and data structures and Unix
    • the basics of web technologies: HTML, JavaScript, CSS
  • Fluent Polish and at least B2-level English speaker

Nice to have


  • Knowledge of Scala and Java
  • Experience in Telco industry
  • Work experience:
