Medior Machine Learning Engineer

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.

As a Medior 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. Ensuring robust monitoring is in place, that predictions seamlessly integrate with operational systems, and that stakeholders know you are building the right thing. You’re more than a model builder: you’re a blend of internal consultant, software engineer, and applied mathematician.

At Picnic, a wide variety of machine-learning models is already running in production. In the Inbound team, you could work on improving the Temporal Fusion Transformer model that predicts article demand on a large scale—a direct input for our ordering system. In our Payment team you could work on our real-time payment fraud detection system— to ensure we block fraudulent orders, not happy customers.

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.
