Overview
Join to apply for the Python Backend Engineer role at Tesco Technology.
Within Tesco Data & Analytics, we find ways to use data to help our customers and the communities where we operate. We build and run Tesco’s data platforms, architect and engineer data onto these platforms, provide capabilities and tools to the analytics community across Tesco, and develop data products at scale. As a backend engineer within Data Science you have the vital role of integrating our capabilities into Tesco's systems which is critical to creating value. You will bring your experience of implementing scalable backend systems to our teams while having the opportunity to work in the exciting ML and AI space.
Our Data Science teams work on projects spanning supply chain, logistics, store and online, including Operations Optimisations, Commercial Decision Support (e.g. Forecasting and Range Optimisation), Online (e.g. Search and Recommendation) and Intelligent Edge (e.g. Computer Vision). Our Machine Learning Engineers collaborate with data scientists to develop tools, optimise code, and deploy solutions on edge, cloud and big-data environments.
