Amsterdam, Nederland Picnic Voltijd

At Picnic, we’re revolutionizing the way people buy groceries with our affordable and sustainable app-only service. We do almost everything in-house, developing cutting-edge technologies and processes to ensure we continue to grow rapidly without missing a beat. If you’re a passionate Machine Learning Engineer, we’re offering you the opportunity to join us at our Amsterdam HQ and make a real difference in our data-driven, scale-up environment. We are currently seeking talented individuals across various levels of expertise.

In a nutshell

As a Senior Machine Learning Engineer at Picnic, you’ll work on creating intelligent, automated systems to solve our company’s biggest challenges, at scale. You won’t stop at building a model—you’ll productionize it alongside the wide variety of machine learning models we already have running in production.

Working closely with business leads and other machine learning engineers, you’ll identify and solve problems leveraging machine learning. When working with our Inbound team, you’ll work on improving the Temporal Fusion Transformer model that predicts demand on the article level—a direct input for our ordering system. With our Payment team you could work on our real-time payment fraud detection system— to ensure we block intentional fraud, not happy customers. You’re more than a model builder: you’re a blend of internal consultant, software engineer, and applied mathematician.

You might think, ‘Sounds good, but 80% of my job is going to be cleaning data.’ Not here. Our data is registered, logged, consistent, and immaculate. We’re a mature team with the infrastructure, tools, and expertise to get models into production.

  • Recommendation systems: generating useful in-app grocery suggestions for our customers
  • Search and ranking: helping our customers find exactly what they need
  • Predicting delivery drop-off times for our distribution: making sure we’re on-time at every customer.

  • Own your own project from inception to production, to continuous improvement
  • Develop tools and enhancements for our cloud-based data science platform

  • You’ll get freshly prepared, healthy lunches and snacks (with plenty of vegetarian, vegan, and halal options). Coffee snob? Don’t worry, our amazing Picnic barista has you covered.
Stay healthy
  • Mental health is important. As well as having the option to speak with Picnic colleagues who act as confidential advisors, our collaboration with OpenUp gives you easy access to professional psychologists, along with workshops and materials.
  • There are plenty of sports communities and events to get involved with, from tennis to yoga to climbing
Attractive package
  • We offer competitive compensation and a pension plan that looks out for your future self as well as 25 vacation days per year, so you can recharge your batteries

Benefits for expats

It can be daunting starting a new job AND moving to a new country. That’s why we offer lots of support for our many expat colleagues, including:

  • Relocation package: If you join Picnic from abroad, we’ll cover your trip to Amsterdam, sponsor your Visa, and offer you a month of accommodation while you settle in (as long as regulations allow).
  • In the Netherlands, we offer support with your first tax report as well as arranging the 30% ruling.
  • From health insurance to living arrangements to pet passports, there are always colleagues who’ve faced the same challenges and are more than happy to help

Commitment to equal opportunities

Applicants will be regarded independently of age, gender identity or expression, sexual orientation, ethnicity, skin color, civil status, religious beliefs, physical or mental disability, or any other factors protected by law.

At Picnic, we celebrate and value our differences and are committed to building a safe and inclusive working environment where everyone can be themselves.



With a data-driven approach, an app-only store and a fleet of electric vehicles, Picnic has become Europe’s fastest growing online supermarket.
