You'll design and build advanced analytical and machine learning solutions that directly impact the growth strategies of brands including the Financial Times, MyProtein and The Independent. As a senior individual contributor, you will own the end-to-end data science lifecycle — from problem framing with clients through to model deployment and insight activation. This is a pivotal role for an experienced data scientist ready to drive real-world business outcomes across growth marketing, CRM, media optimisation, and beyond.
We understand that no one can do everything — this role spans a wide remit. We're looking for someone with deep skills in some areas and genuine interest in developing others. The scope of the role will flex depending on your strengths.
What You'll Do
- Develop LTV, propensity and attribution models to support growth, customer experience, and paid media

- Build MMM and bespoke models in response to client needs
- Apply forecasting, clustering, NLP and causal inference techniques where appropriate
- Ensure outputs are practical, explainable and drive business decisions
- Own model deployment and monitoring in cloud environments (GCP, AWS or similar), ensuring models remain robust in production
- Define reporting strategies for stakeholders — who needs what, when, and why
- Design high-impact BI dashboards that bring clarity and insight
- Deliver recommendations that are both data-rich and action-focused
- Configure analytics tools such as GA4 and Adobe Analytics to track the right data
- For smaller clients: centralise and clean marketing data using proprietary tools
- For larger clients: manage ETL processes and build scalable, clean tables
- Lay strong data foundations to enable analytics, reporting and modelling
- Write production-quality SQL and Python for data pipelines, transformations and model inputs
- Deploy and maintain models using GCP, AWS or similar; familiarity with MLOps tooling (e.g. Vertex AI, MLflow) a plus
Consulting & Client Management
- Serve as a trusted analytical partner to senior client stakeholders, translating complex data science outputs into clear business recommendations
- Translate analysis into actionable guidance for media, CRO, CRM and creative
- Lead insight and trading meetings with clients, owning the narrative and driving decisions
- Proactively identify analytical opportunities within client accounts and shape the roadmap for data science work
- Help teams across In Digital and our clients make better, more data-informed decisions
What We're Looking For
- 4-5+ years' post-graduate industry experience in a data science (or similar) role, with a minimum of 1 year working on Marketing Mix Modelling (MMM)

- Solid experience in at least three of the key responsibility areas above
- Expert-level SQL and Python (pandas, scikit-learn, statsmodels or similar); R also welcome, plus BigQuery or Snowflake
