We place great importance on who you are as a person. You enjoy sharing knowledge, helping colleagues and contributing to a collaborative environment. You are comfortable taking responsibility for your work while knowing when to involve the rest of the team.

A few words from the manager

Infrastructure Applications is a team with broad technical responsibility and a lot of knowledge. We operate platforms that are important to many parts of Tele2, which means that what we do genuinely matters.

As a manager, I value trust, openness and collaboration. I want people in the team to have the freedom to take ownership, challenge existing ways of working and develop in the technical areas that interest them. We have a strong team culture where we help each other, share knowledge and solve problems together.

If you enjoy understanding how things work, solving challenging technical problems and want the opportunity to develop across several infrastructure areas rather than being limited to a single technology, I think you will enjoy working with us.
