We are looking for an experienced Marketing Mix Modelling (MMM) practitioner to join our Marketing Science & Effectiveness team. This is an opportunity to take ownership of high-impact client programmes, applying your expertise to shape how leading brands measure and optimise marketing performance. You will act as the central driver of projects; defining analytical approach, shaping inputs into modelling, interpreting outputs, and translating these into clear, commercially relevant recommendations. Working closely with clients and collaborating with cross-functional teams across our globally distributed delivery model, you will bridge data, modelling, and business context to ensure high-quality, impactful outcomes. This is a hands-on role combining strong client partnership skills with analytical delivery, requiring a high degree of ownership and autonomy.

• Lead MMM engagements end-to-end, owning delivery from data inputs through to insight generation and final client recommendations that drive client impact and commercial success.
• Own day-to-day client relationships, building trusted partnerships and translating business questions into clear analytical approaches and actionable marketing recommendations.
• Ensure modelling inputs and outputs are robust by reviewing, shaping, and challenging data, assumptions and results to support credible decision making.
• Define and refine media frameworks and channel structures to ensure modelling reflects marketing activity and enables meaningful, decision-ready insights.
• Convert modelling outputs into commercially compelling ROI stories, including optimisation scenarios and budget allocation recommendations.
• Coordinate cross-functional teams across a globally distributed delivery model, ensuring alignment between data, modelling, and client priorities throughout delivery.

• Strong experience contributing to or leading MMM programmes or similar analytical projects, with the ability and readiness to take ownership of end-to-end delivery.
• Ability to interpret complex analytical outputs and communicate clear, commercially relevant recommendations that support marketing and investment decisions.
• Experience working with media and sales data, with the confidence to review, challenge, and shape inputs and outputs to ensure robust modelling outcomes.
• Strong client management skills, with experience building trusted relationships and delivering a high-quality, effective client experience.
• Demonstrated ability to coordinate cross-functional project-based teams and manage multiple priorities in a fast-paced distributed delivery environment.
• Strong understanding of marketing effectiveness and measurement, with experience across sectors such as FMCG, Retail, Financial Services or Media.

• Location: London or Warwick, with a hybrid working pattern (typically 2 days per week in the office).
• This role is delivered through a globally distributed delivery model.
• Candidates must have the right to work in the UK (no sponsorship available).
