• Agency partner: Maintain regular contact with our econometrics agency partners. In this position you will manage the flow of requests, ensure adherence to briefs, and interrogate recommendations where necessary. Internally you will champion their work and ensure engagement with the output.
• Evolution and innovation: To maximise the impact and effectiveness of our model, you will consider opportunities to further improve the data feed. By maintaining knowledge of industry best practice, and building a strong relationship with relevant contacts, you will have the opportunity to maximise the impact of MMM throughout the wider business.
• In collaboration with channel managers, you will manage the measurement framework and experimentation roadmap. In which we will detail our test and learn priorities that you will spearhead as the year goes on.
• Learning Prioritisation: Own the rollout of the experimentation and measurement roadmap. Ensuring the tests deemed most important are executed in timely and rigorous manners.
• The "Knowledge Bank": Maintain the central test & learn log. Documenting every outcome, and sharing those with wider stakeholders to ensure that learnings are actively used to ameliorate media plans.
• Technical Translation: Collaborate with specialists and analysts to take ambitious ideas from Channel Leads (owned and paid), and translate them into technical briefs for specialists to build.
• Initiative Support: Design and set up cross-channel Test & Learn initiatives, including A/B testing, Meta/Google Lift studies, and regional Geo-tests across both owned and paid media.

• Experience with both paid and owned media with an ability to evidence the nuances in their measurement challenges.
• Proven experience working across multiple media channels.
• Proven experience working with, Marketing Mix Modeling, Multi‑Touch Attribution, and Incrementality Testing.

• Experience managing relationships with third‑party measurement partners.

Other things we’re looking for (key criteria)
