About The Company
At Picnic, we’re revolutionizing the way people buy groceries. Our affordable and sustainable service is made possible by our passionate people, cutting-edge technology, efficient planning, and, of course, our fleet of iconic electric vehicles! It’s why our customer base is growing rapidly across the Netherlands, Germany, and France. One of the things that makes Picnic different is that we handle almost everything in-house: forecasting, developing our first automated warehouse and new electric Picnic vehicles, internal and customer-facing applications—the list goes on. It gives us more freedom when it comes to trying out new and innovative ideas, which is something we do a lot! We love to challenge ourselves and learn new things. Our teams have access to various meetups, language classes, ‘Lunch & Learn’ sessions, our very own Tech Academy, and tailored soft-skills training. Professional development is as important to us as the service we provide to our customers. As a diverse team made up of over 80 nationalities, there are always plenty of activities to get involved with, whether you’re into sports, board games, charitable causes, dancing (at our legendary Picnic festival), or licorice tasting—yes, even that! Our scale-up culture means you get to own your role and bring fresh ideas to the table. So, if you’re looking for an opportunity to make a real difference, get in touch—we’d love to hear from you.
About the Role

In a nutshell

Own an end to end project in a real production environment as an integral part of one of our teams. At Picnic your skills will be taken to the next level with the latest tech! And our diverse set of projects will keep you challenged and motivated. From optimizing large-scale vehicle routing with advanced solver technologies, to productionizing AI-driven quality gates in our release pipelines, you’ll work on problems that directly impact our operations. You might even find yourself building robust testing frameworks for automated warehouse systems, bridging the gap between software and real-world logistics.

We don’t hide what we do. Instead, we open-source with the community that helped us grow. Here’s proof: http://picnic.tech
