Data Scientist

Role Overview

• Join the Data Science team at The Telegraph and work on applied machine learning problems at scale.
• You will design, build and deploy models that power key parts of our digital products.
• This includes working across the full lifecycle, from data exploration and model building through to productionisation and monitoring.
• You will partner closely with Engineering, Subscription, Product and Editorial teams to translate business problems into robust, data-driven solutions.
• The work spans areas such as optimisation, personalisation and prediction, with a strong focus on measurable impact.
• This could include dynamic pricing, churn propensity modelling, content recommendation systems, and building ML-driven signals to support newsroom decision-making.
• This role offers the opportunity to work with modern tooling and large, real-world datasets, while contributing to a team that values pragmatism, experimentation and continuous improvement.
• End-to-End Technical Ownership: Take accountability for the ML lifecycle, from initial data cleaning and exploration to developing, deploying, and maintaining production-grade models and pipelines.
• Experimental Rigor: Design, execute, and iterate on experiments with clear success metrics, ensuring solutions create measurable business impact.
• Stakeholder Partnership & Communication: Act as a bridge between technical and non-technical teams by framing complex problems clearly, aligning solutions with business constraints, and delivering actionable findings.
• Operational Excellence: Improve existing systems through iterative feature engineering and robust monitoring, while working alongside engineers to ensure all solutions are scalable and maintainable.
• Strategic Opportunity Identification: Proactively identify and scope new areas for optimisation, personalisation, or automation that align with broader business goals.
• Team & Industry Leadership: Uphold and evolve team standards for code quality and experimentation, providing peer mentorship and integrating modern ML developments where they provide value.

Requirements

• Experience applying data science or machine learning to real-world problems, through industry work, research, or applied projects
• Strong Python skills, with practical use of data science and ML libraries (e.g. pandas, NumPy, scikit-learn or equivalent)
• Solid SQL skills and experience working with large, structured datasets
• Good understanding of core machine learning concepts, including model training, evaluation, and feature engineering
• Exposure to generative AI or LLM-based systems (e.g. prompt design, evaluation of outputs, and integrating third-party model APIs into data products or pipelines)
• Familiarity with software engineering practices such as version control (Git) and writing reproducible, maintainable code
• Ability to translate ambiguous problems into data-driven solutions and measurable outputs
• Strong collaborative mindset, with a proactive approach to problem solving
• Clear communication skills, with the ability to explain technical approaches and trade-offs to non-technical stakeholders

Tech Stack

• Numpy
• Pandas
• Python
• Scikit-Learn
• SQL
