Frontend Developer - Retail Media

Working with and for a smile

At Jumbo, our ambition is to be the most customer-oriented company. We want to surprise our customers and exceed expectations so they enjoy doing their shopping with us. With over 700 stores in the Netherlands and Belgium, the option to have groceries delivered via jumbo.com, our own distribution centers, and our colleagues at the head office, we work together every day to achieve that goal. Collaborating to win the hearts of our customers – that’s what we stand for at Jumbo.

As a Frontend Developer, you will play a key role in supporting Jumbo’s Retail Media ambitions. Retail Media is a rapidly growing area within Jumbo, and our challenge is to meet the increasing demand for campaigns from our advertisers by developing more efficient technical solutions. This enables us to better support campaigns operationally and to share results clearly, accurately, and quickly. That’s why we’re looking for the best developers.

Let’s get started – this is what you'll do

We are currently setting up a new team focused on the timely and accurate delivery of campaign results. This team was created from a business case to realize our data ambitions for Retail Media. As a Frontend Developer, you will help build a web interface that allows advertisers to easily view their campaign performance. You will be responsible for all frontend solutions within the team (such as embedded PowerBI dashboards), act as the main point of contact, and help define the frontend strategy.

You’ll work closely with the Data Engineers, supporting them with practical solutions to ensure that advertiser data is offered efficiently via the portal. Your goal: to help deliver the best data-driven Retail Media solutions for Jumbo. You’ll also collaborate with other teams and enjoy challenging colleagues to do things a little differently.

We’re starting the build this year, aiming to go live in summer 2026. After that, we’ll continue developing the platform with this team to achieve our long-term Retail Media goals.

Together we are Jumbo – where you’ll be working

There’s always something happening at Jumbo. No two days are the same; we move quickly and constantly look for ways to improve. We encourage you to spot opportunities and take initiative.

The Agile team will consist of a Product Owner, two Data Engineers, a Backend Developer, a Frontend Developer, and a QA Engineer. As Frontend Developer, you’ll be part of the broader Customer & Assortment department.

At Jumbo, we’re looking for go-getters — people with great ideas and the courage to put them into action together. People who care about those around them: our customers, colleagues, and the world beyond. We strive to do things a little better every single day. All our (future) colleagues share a healthy dose of Jumbo DNA — and so do you!

In addition, you bring:

• At least 5 years of experience as a Front-end Developer

At Jumbo, you’ll find a work environment with warmth, enjoyment, and attention for each other. Where you have plenty of room to contribute to our ambition of becoming the most customer-oriented company. Just as you’re there for our customers, we’re there for you. Additionally, you’ll receive:
