Senior Applied Scientist - Network Behaviour… at Zalando · Dortmund

Senior Applied Scientist - Network Behaviour (all genders) Location: Dortmund THE ROLE & THE TEAM One of the main drivers for conversion in online retail is the delivery promise, informing fashion customers about when they can expect their shipment to arrive. Our team owns the forecasting of processing times for all the paths in the complex fulfillment network on which this delivery promise is based.

Our team is composed of applied scientists and software engineers. As an applied scientist, you’ll design, train, extend, and continuously improve forecasting models based on features extracted from diverse datasets produced by high-throughput systems. You’ll do so in close collaboration with the software engineers in your team, who are responsible for building best in class services and infrastructure for experimentation and applying these models in production. A significant part of your role will be to research new opportunities and work closely with stakeholders to understand the underlying business processes and model them in the best possible way to feed into our models. If you have a passion for creating forecasting models at scale and solving complex problems, we want to hear from you. This is a unique opportunity to make a real impact and help drive the success of our business. INCLUSIVE BY DESIGN At Zalando, our vision is to be inclusive by design.
