ROLE SUMMARY:
The role is a rare opportunity to be right at the forefront of media and brand analytics, leveraging a leading global platform and Data Science team to aid the biggest marketers with game changing solutions around the measurement, optimisation and planning of media. Through cutting edge solutions in analytics and marketing science that will be at your disposal, you will help the biggest brands in the industry with understanding the value of their media, define their optimal media plan, and feed insights straight into their media buying strategies.
You will:
Impress clients! Work on client engagements, helping run analysis to understand media impact like (e.g. MMM or attribution), and custom projects on how to optimise media plans to maximise a client’s KPI.
Facilitate the best in class! Whether it is being the expert on a new regional data set, or training other analysts on a new solution, you will help ensure that our best practice marketing solutions are supported and effective.
Learn and share! As a specialist in the region with dozens of markets, you will learn and share your work in a wide community of data scientists, marketing scientists and analysts. This could include AI agents or optimisation processes , code bases, etc.
This role is perfect for an experienced analyst, with existing capabilities like MMM, attribution or advance optimisation of media plans, that wants to broaden their technical capabilities and progress towards the path of a manager in the regional Data Science team. Whilst the focus of the role is measurement-based analytics, as part of the Data Science team there will also be the opportunity to work on broader data science projects that can enhance and innovate our solutions.

(E.g. – we have several pieces of code in Python and R that are in development, and the senior analyst would take the current solution, test, collate feedback, understand the gaps, and work with the manager and director to define improvements, and work with fellow data scientists to ensure those are in development and tracked. The senior analyst might also be assigned some of these tickets where their technical skill is appropriate and personal development is aligned).
Effectively communicate marketing science/data science concepts and the results of analyses to both internal, and client teams
Attend training sessions, seminars and workshops, and generally be abreast to the latest in tracking, measurement, mar-tech and ad-tech space.
