Backend developer, Java

3 days ago


Stockholm, Stockholm, Sweden 3 Sverige Full time

Do you want to work in a culture where innovation, collaboration, and development are at the center? At Tre, you'll be part of an engaged team where your technical skills make a real difference – both for our customers and for society.

IT Customer Management is part of the IT Development organization and consists of 31 employees and consultants. Right now, we're taking over responsibility for developing and integrating with our Customer Contact systems. This is an exciting phase where we are establishing new architecture and working methods to create future-proof and efficient solutions.

About the role

As a backend developer in Java, you will be key in integrating backend functionality with our Contact Center platforms, Genesys Cloud, Zendesk and Boost.ai. You will enhance existing applications while also building new solutions from scratch. Your work spans the entire development process from analysis to implementation, in close collaboration with IT architects, developers, and customer service stakeholders. While primarily focused on backend development, you may occasionally support frontend tasks. Balancing technical details with a broader perspective, you will ensure our solutions are modern, efficient and aligned with the business needs of our customer service organization and systems.

Our Tech Stack

We are modernizing our systems and work with Java, Spring Boot, Openshift, TypeScript/JavaScript, Next.js, and React.

You will look forward to
  • Being a key part of the architectural journey for the Customer Contact systems and taking technical responsibility for our integration implementations
  • Working at a company that delivers critical infrastructure where your contribution directly contributes to societal benefits
  • Being part of one of Sweden's best workplaces according to Great Place To Work
  • Belonging to an employer that strives to contribute to women choosing and staying in the tech industry; we are proud partners of Women in Tech and Tjejer Kodar
A bit more about you

We are looking for a curious and collaborative person who enjoys taking responsibility and contributing to a supportive team environment. You have experience in backend development with Java and feel comfortable working with complex systems. If you also have some knowledge of React, JavaScript and/or TypeScript, that's great, as it allows you to contribute more broadly when needed. Since you will work closely with different teams, good communication skills are valuable, and you should feel comfortable discussing technical solutions in both English and Swedish.

Having experience with technical migrations is an advantage, and if you are familiar with Genesys Cloud or Zendesk, that is another very good bonus—but not a requirement. AI knowledge and chatbot experience are further advantages.

Most importantly, you are eager to learn, grow, and be part of a team that values innovation, collaboration, and diversity.

Welcome with your application

We are accepting applications via this job ad, and interviews are ongoing. A personal letter is not required, but we would like you to answer the questions we ask in connection with your application. We use tests to ensure objective assessments in the selection of candidates. The position may be filled before the application deadline. Background checks are carried out on the final candidate. We refrain from consulting requests.
