At Tesco, we have a mature team of 50+ Data Scientists and 20+ Machine Learning Engineers who focus on modelling complex business problems and deploying data products at scale. Our work spans multiple areas including physical stores, online, supply chain, marketing and Clubcard, where we encourage rotation amongst our Data Scientists so they can gain expertise in different subjects.
We work on several domains and problem types: online, pricing, security, fulfilment, distribution, property, IoT and computer vision are just some. Our team members are encouraged to allocate working hours for learning and personal development every week and are provided with multiple learning resources and tools. Multiple academic collaborations enrich the team expertise; knowledge-sharing events are regular.
Furthermore, we have got a great work-life balance, team days and relaxed but engaging culture.
Office Location: You can choose to be based out of either the London or Welwyn Garden City office
This is a hands-on/Individual Contributor position where you will need to leverage your analytical mindset to find solutions to complex problems. This role does not require line management. As a Lead Data Scientist, you will need to understand difficult business problems and prototype solutions in complete independence. To design, develop & deploy algorithmic solutions and mathematical/statistical/machine learning models to solve business problems on top of big data architectures (Hadoop, Spark) is a core component of the role. Our data scientists need to be able to validate, document and present the modelling process and performances, as well as communicating complex solutions in a clear, understandable way to non-experts. Data Scientists are also responsible for promoting data science across Tesco and promote Tesco across the external Data Science community. Finally, as a Lead Data Scientist who specialises in probabilistic modelling, you will be expected to curate your area of expertise—managing relevant projects through to productionisation—provide technical leadership and actively participate to talent development. You will be expected to drive innovation, partner with Data Science Managers and Product Managers to manage the relationships with the business stakeholders, and mentor/supervise junior members of the team and/or interns. You will be considered the team’s subject matter expert in probabilistic modelling & Bayesian methods for ML and be expected to share your knowledge and upskill your teammates by delivering training sessions.
We are looking for ambitious individuals with a mix of machine learning, statistics and programming skills. The role requires that you have an extensive background in developing probabilistic models (e.g. hierarchical Bayesian models) at scale leveraging common frameworks such as PyMC3, Stan, Edward and others. Project and stakeholder management experience is also required.
An ideal candidate will have a scientific mindset with the ability to ask the right questions, as well as answer them. A strong quantitative higher degree in mathematics, sciences, statistics, engineering or computing is preferable, as well as a solid in-depth understanding of the mathematics and statistical principles behind modern ML algorithms.
Finally, strong programming skills are essential (Python is preferred) as well as awareness of the SWE best practices (such as version control, unit testing, CI/CD) and big data & cloud technologies (PySpark preferred).
We offer excellent benefits that help make Tesco a great place to work. These include but aren’t limited to:
Our vision here at Tesco is to become every customer's favourite way to shop, whether they are at home, out shopping, on the move, anywhere in the world.
In order to enable our vision, we strive to simplify operations for our Colleagues, Partners & Vendors to enable efficient trade.
Everything is underpinned by our continuous drive for the best tools and technology to deliver our vision. We’re driving innovation and transforming our Technology to become the world’s leading retailer.
We need people who share our ambition to deliver for our stakeholders. Passionate and confident people willing to take the initiative and drive us forwards. In return, we offer excitement, a great team, an excellent benefits package, and significant career development opportunities.
Joining us means playing a part in defining; building and launching an ambitious roadmap of digital products that could affect the lives of millions of people over the years to come.
If that sounds exciting, then we'd love to hear from you.
The position will be based in either our London (Farringdon) office or our Welwyn Garden City campus.
