Responsibilities
As a Data Scientist at Tesco, you will develop and deploy machine learning, computer vision and generative AI solutions that directly impact how we serve our customers and run our business. You will design and implement robust models, experiment with new approaches, and translate business problems into data science solutions. This includes building prototypes, evaluating model performance statistically and in terms of business impact, and scaling models into production. You will collaborate closely with Machine Learning Engineers and Software Engineers to ensure solutions are efficient, maintainable, and aligned with Tesco's technology standards.
You will also play a key role in communicating complex ideas clearly to non-technical stakeholders, contributing to internal knowledge sharing and representing Tesco in the external data science community. Staying current with developments in GenAI and Computer Vision will be essential, as you will help evaluate and integrate emerging techniques into our data products.
Qualifications
We are looking for a curious and driven individual with a strong background in computer vision solutions. A mix of statistics and machine learning skills are also welcome. A track record in modifying and designing advanced algorithms and applying them to large real‑world data sets is fundamental. You will translate business problems into data science solutions and communicate your findings clearly to both technical and non‑technical audiences. A scientific mindset, critical thinking, and the ability to ask the right questions are essential. You will be proactive in learning new methods, staying up to date with the latest developments, and contributing to a culture of knowledge sharing and collaboration.
A higher degree in a quantitative discipline – such as Mathematics, Computer Science, Engineering, or Physics – is preferred, though equivalent experience in a commercial setting is also valued. Strong coding practices, including version control and testing, are expected.
Ideally, you have experience with:
* Deep Learning frameworks: TensorFlow and/or PyTorch
* Object detection models, e.g. Faster‑RCNN, YOLO, EfficientDet, Nvidia models
* Libraries and tools: OpenCV, scikit‑image, SciPy, Pandas, Docker, Git
* Working knowledge of image processing and video technology
