Software Engineer

Ready to take technical ownership of systems that process some of Sweden’s largest data volumes?

At Tele2, Digital Capabilities & Technology (DCT) is the engine behind our mobile and fixed networks. Within Network Data, our Performance Management team builds and operates the in-house systems that collect, process and analyze performance data across all network domains.

We are now looking for a Senior Software Engineer who wants to play a key role in evolving and modernizing our core performance systems.

About the team

You will join a highly technical team of developers, architects and analysts responsible for Tele2’s Performance Management platform. We collect and process large-scale telemetry and statistics from mobile and fixed networks, transforming raw data into insights that drive operational and strategic decisions.

We are in a transition phase – modernizing parts of our stack and reducing dependency on external consultants by strengthening our internal engineering capability. This means you will have real influence over architecture, technical direction and ways of working.

Take technical ownership of critical services

Contribute to system design and architectural decisions

Improve performance, scalability and reliability

Mentor and elevate the engineering standards of the team

You will work in a Linux-based, containerized environment handling high-volume data streams and backend services.

Your responsibilities

Design, develop and evolve backend services in Go and/or Java

Improve and optimize high-throughput data processing pipelines

Drive best practices around CI/CD, testing and code quality

Operate and troubleshoot systems in production

Collaborate with architects, analysts and network stakeholders

Contribute to long-term system design and modernization initiatives

Participation in on-call rotation may be part of the role.
