Senior 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.

🥜 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.
