Job description

 

Let’s get started! What you’ll do:

We’re building a new team focused on delivering campaign results quickly and accurately for our advertisers, a key step toward achieving our Retail Media goals. As a Software Development Engineer in Test (SDET), you’ll work on a web interface that allows advertisers to easily access their campaign performance. Within the team, you’ll be the go-to person for all quality-related matters and actively help shape a shared quality mindset.

Developers contribute to testability and quality, while you, as an SDET, are also involved in developing both frontend and backend features. In this way, quality assurance becomes a shared responsibility, and together we build robust, scalable software with quality at its core.

Your expertise enables us to deliver reliable, data-driven Retail Media solutions for Jumbo. You’ll collaborate closely with other teams, business stakeholders, and relevant chapters — and you’ll inspire your colleagues to think outside the box. This greenfield project kicks off this year, with a go-live planned for summer 2026. After that, we’ll continue building on our ambitions together.

Together we are Jumbo: this is where you'll work

A lot happens at Jumbo: no day is the same, we move fast and are always looking at how we can improve, for our customers and each other. You’re encouraged to spot opportunities and take initiative on anything that helps us reach our goals. With an informal working atmosphere, room for ownership, humor, and fun, you’ll work at Jumbo with a smile every day. The Agile team will consist of at least a Product Owner, two Data Engineers, a Backend Developer, a Frontend Developer, and a Software Development Engineer in Test. As an engineer, you’ll be part of the broader Customer & Assortment department.

 

  • At least 5 years of hands-on experience with quality-driven software development
  • Experience with technologies such as Java 21, Spring Framework, JavaScript, TypeScript, or Vue/Nuxt
  • Strong knowledge of test automation and performance testing
  • Skilled in designing and implementing test strategies within Agile teams
  • Ability to foster and sustain a strong quality culture within the team
  • Experience with cloud platforms like AWS and/or Azure
  • Familiarity with CI/CD processes and tools such as GitHub

 

And finally...

You have a strong Quality Mindset and live it from design through to production. You help create awareness and foster a team culture focused on quality — reliable, testable, and sustainable. With your solid engineering skills, you easily switch between testing and development, always keeping the bigger picture in mind.

 

 

  • As a Software Development Engineer in Test (SDET), you develop test strategies and quality solutions. You contribute to building both frontend and backend functionality, ensure quality, and promote a shared quality culture within the team.
  • By delivering robust, scalable software and reliable testing processes, you ensure Retail Media solutions work flawlessly. This strengthens Jumbo’s digital propositions and provides advertisers with accurate, data-driven insights.
  • You work in a new Agile team with a Product Owner, Data Engineers, Backend and Frontend Developers. Together, you build a web interface and solutions that support Jumbo’s Retail Media ambitions.
  • You collaborate with business stakeholders, other IT teams, and relevant chapters to ensure quality assurance, drive innovation, and achieve a successful go-live of new Retail Media solutions in 2026.
