Econometrics Consultant | Marketing Effectiveness | London | Up to £60k

We're working with a global marketing effectiveness consultancy that helps brands get the most return from their media spend. They're looking to hire an Econometrics Consultant to join a small, specialist team.

This is a great opportunity for someone with hands-on Marketing Mix Modelling experience who wants to own whole projects from start to finish. You'll report directly to a Principal Consultant, work with household-name brands and have the chance to become a true specialist in media effectiveness, with strong training and development along the way.

The role will involve:

  • Building Marketing Mix Models from scratch
  • Presenting model results and recommendations to clients
  • Running geo-tests to measure the impact of campaigns
  • Forecasting how changes in budget will affect performance
  • Advising clients on where to move spend for the best return
  • Working closely with clients and internal stakeholders throughout each project

We're particularly interested in candidates from MMM consultancies or the effectiveness and analytics teams within media agencies.

You'll need proven experience building and delivering MMM models yourself, with econometrics at the core of your background. Strong analytical and numerical skills are essential, along with strong Excel. You can build models in whatever tool you prefer, whether that's Excel, Python or R.

Confident client-facing and presentation skills are also essential, as this role involves working directly with clients rather than sitting behind a screen all day.

Salary: Up to £60k
Location: London
