Senior Machine Learning Engineer

Join Picnic as a Senior Machine Learning Engineer

As a 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. That means putting robust monitoring in place, ensuring predictions seamlessly integrate with operational systems, and working closely with stakeholders to make sure you're solving the right problem. You're more than a model builder: you’re a blend of internal consultant, software engineer, and applied mathematician.

We work either embedded within business teams or very closely alongside them to ensure our models drive real-world impact. At Picnic, a wide variety of machine-learning models are already running in production. In collaboration with the inbound team you might help improve the Temporal Fusion Transformer model that predicts article demand on a large scale, a direct input for our ordering system. In the Meals team, you could contribute to our two-tower recommender model, helping customers plan their weekly menu with the most relevant and inspiring meal suggestions.

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.

Tricks of the trade

• Identify and execute improvement possibilities together with other ML Engineers and (product) analysts
• Collaborate on your project from inception to production, to continuous improvement
• Develop tools and enhancements for our cloud-based Machine Learning platform

Potential project areas include:

• Demand forecasting: delivery, article, trip volumes, used Picnic-wide
• Fraud detection: helping us keep troublemakers out of our store
• Recommendation systems: generating useful in-app grocery suggestions
• Search and ranking: helping our customers find exactly what they need
• Predicting delivery drop-off times: making sure we’re on-time at every customer’s door
• Vision: ensuring quality control and smooth operations within our warehouses

We’re looking for

• Master’s degree or higher in AI, Computer Science, Mathematics, or a related field
• 5+ years of experience in data science or applied machine learning
• Excellent communication skills, able to clearly explain complex ideas in non-technical terms and enjoy working closely with business stakeholders to solve problems together
• Experienced in designing, deploying, and maintaining production ML systems, with solid software engineering and ML principles
• Strong Python and SQL skills
• Able to define the long-term vision and technical architecture for ML solutions within your domain
• Experience with Docker, Kubernetes, and CI is a plus
