About the role
At Tesco, our Data Science team builds scalable solutions to complex business challenges across stores, online, supply chain, marketing and Clubcard. We apply advanced machine learning, generative AI, and large language models (LLMs) to personalise customer experiences, optimise operations and drive innovation. We work across several business domains, including customer experience, online, fulfilment, distribution, commodities, store operations and technology. Team members rotate across domains to broaden their expertise and impact.
We foster a culture of continuous learning, dedicating 10% of the working week to personal development. Our team benefits from academic partnerships, regular knowledge-sharing events and a collaborative, inclusive environment that values work-life balance and professional growth.

You will be responsible for
We are seeking an AI Data Scientist to help build intelligent systems that go beyond prediction—systems that can reason, act, and adapt to real-world challenges. This is a hands-on role where you will work across the full lifecycle of AI projects, using large language models (LLMs) and agentic AI techniques to develop practical solutions for business problems.

You will design AI systems that are technically sound, scalable, and safe, while keeping business constraints in mind. Collaboration is key—you’ll work closely with stakeholders to understand their needs and translate them into effective AI solutions. Clear communication is essential, whether you're documenting your work, presenting results to non-technical audiences, or supporting product managers and lead scientists.

A core part of the role involves shaping how agentic AI is applied across different areas, ensuring systems can make decisions independently while staying within safe and defined boundaries.
You’ll join a team that values curiosity, practical thinking, and continuous learning. There will also be opportunities to share your work with the broader AI community.


You will need

· Broad understanding of LLM architectures, training methodologies, and usage patterns.

· Practical experience applying LLMs, including:

· Managing context windows effectively

· Selecting appropriate models for specific tasks

· Implementing safety guardrails and alignment techniques

· Decomposing complex tasks into model-friendly components

· Strong experience in evaluating and validating data pipelines and ML systems.

· Familiarity with AI-specific evaluation methods, including both quantitative metrics and qualitative assessments.

· Ability to make well-reasoned decisions grounded in technical understanding and real-world constraints.

· Pragmatic approach to experimentation and solution design.

Values

· Actively engaged in learning and staying current with developments in AI and machine learning.

· Curious, adaptable, and committed to continuous improvement.

The Future of Data Science Jobs: Careers That Don’t Exist Yet

Data science has rapidly evolved into one of the most important disciplines of the 21st century. Once a niche field combining elements of statistics and computer science, it is now at the heart of decision-making across industries. Businesses, governments, and charities rely on data scientists to uncover insights, forecast trends, and build predictive models that shape strategy. In the UK, data science has become central to economic growth. From the NHS using data to improve patient outcomes to financial institutions modelling risk, the applications are endless. The UK’s thriving tech hubs in London, Cambridge, and Manchester are creating high demand for data talent, with salaries often outpacing other technology roles. Yet despite its current importance, data science is still in its infancy. Advances in artificial intelligence, quantum computing, automation, and ethics will transform what data scientists do. Many of the most vital data science jobs of the next two decades don’t exist yet. This article explores why new careers are emerging, the roles likely to appear, how current jobs will evolve, why the UK is well positioned, and how professionals can prepare now.
