Java/Kotlin Backend Developer — Mid to Senior Level

Telia Play

2 million subscribers across the Nordics

.

I’m

Tomas Brimor, Engineering Manager for Team Enrichment & API at Telia Play

, and I’m looking for someone who wants to grow with us.

We are a supportive, forward-thinking, scrum-sized team building and operating the high-performance metadata platform that powers the Telia Play experience. Our platform processes

nearly half a million metadata events daily

, with proven capacity to handle

peaks exceeding 2 million events

during high-demand periods.

We are open to both

experienced senior developers

and

strong mid-level developers ready to grow into broader technical ownership

.

What matters most is that you have solid backend engineering skills, take ownership, and enjoy building reliable software with real production impact. You do not need to have worked with every part of our stack already — curiosity, ownership, and the ability to learn are just as important.

We value

pragmatic engineering, open discussions, shared ownership, and continuous improvement

over rigid hierarchy.

What you’ll do

You will work at the core of our metadata ecosystem, helping us aggregate, normalize, enrich, and deliver metadata efficiently across the Telia Play platform.

In this role, you will:

Build and improve backend services

using

Java

,

Kotlin

, and

Spring Boot

.

Design, develop, and operate event-driven systems

using AWS services such as

SNS, SQS, and Kinesis

.

Create and maintain APIs, integrations, and metadata pipelines

that support the Telia Play experience across the Nordics.

Improve reliability, performance, observability, and correctness

in high-throughput production systems.

Contribute to architectural decisions

around scalability, resilience, maintainability, and cloud-native ways of working.

Take ownership from idea to production

, following our “you build it, you run it” mindset — and, depending on your experience level, help mentor others and raise engineering quality.

What will help you thrive in this role

We are looking for someone who is proactive, curious, collaborative, and comfortable taking responsibility beyond just writing code.

You will likely thrive here if you have:

Solid backend development experience

with

Java and/or Kotlin

, preferably in production systems with real users and operational responsibility.

Experience with Spring Boot

, APIs, integrations, microservices, and modern backend development practices.

Good understanding of distributed systems

,

SQL and/or NoSQL databases

, and cloud-native development, preferably in

AWS

.

Interest in infrastructure as code, automation, and delivery practices

, for example using

Terraform

.

A quality mindset:

you care about maintainability, observability, security, performance, and correctness.

Comfortable communication in English

across teams and countries.

Interest in AI-assisted software engineering:

you are curious about practical ways AI can support development workflows, code quality, automation, or problem-solving.
