Responsibilities  

Specific responsibilities include but are not limited to:

Develop and maintain media buying optimization algorithms through AI and ML to drive greater campaign outcomes against an array of KPIs

Create audience segmentation and addressability models to enhance targeting precision across multiple targeting keys

Generate actionable campaign insights from complex datasets to improve campaign planning through actionable insights

Implement yield management strategies to maximise supply utilisation across the addressable TV portfolio

Build and refine forecasting models for campaign performance for multiple channels

Design and analyse A/B tests to improve campaign effectiveness measurement

Assist in developing robust campaign measurement methodologies

Modelling and methods

Strong Python and SQL, comfortable working with large, imperfect datasets.

Supervised machine learning across classification and regression, with the judgement to choose the right approach for the problem rather than defaulting to one method, including where standard linear assumptions do not hold, and quantifying uncertainty where a forecast carries commercial weight such as pricing or guarantees.

Experience with experimental design, causal inference and quasi-experimental methods, including geographic experimentation (GeoLift) and test-and-control.

Audience and customer segmentation using unsupervised methods, defined so segments can be activated rather than just described.

Budget allocation and channel-mix work, including marketing mix modelling and the saturation and diminishing-returns dynamics behind it.

Tools and delivery

Building reusable, documented tools and self-service products rather than one-off analysis.

Dashboarding (Streamlit, Dash, Power BI or Tableau) and clear visual presentation of analytical work.

Git and reproducible development, with cloud platforms and model deployment an advantage.

Ways of working

Turning vague business questions into measurable problems, and judging honestly whether the data can support the analysis being asked for.

Explaining technical work without jargon and presenting results as commercial recommendations, with assumptions and uncertainty made clear.

Comfortable with clients and senior stakeholders, challenging unsuitable requests constructively, and working through ambiguity and shifting deadlines.
