Media Manager, Effectiveness Operations in City of Westminster

Workplace: White City, London – 2 days a week in the office.

Overview

We are looking for a proactive, detail‑oriented “doer” to become the operational engine of our measurement framework. This role will plan, lead and unify the cross‑channel delivery of testing solutions to improve channel effectiveness. Sitting at the intersection of our Media Channel Leads and our Analytics specialists, you will ensure our Marketing Mix Models (MMM) are fed with the right data and that our Test & Learn ideas are translated into rigorous, actionable experiments. You will be the guardian of “what works,” ensuring every lesson we learn is recorded and, crucially, applied to our future media output.

Responsibilities

• MMM Operations & Data Stewardship
• Data Supply Chain – Serve as the primary point of contact for all data sharing and queries from MMM partners, managing the timely process of gathering, cleaning and formatting media spend/delivery and performance data for our Econometric (MMM) models.
• Accuracy & Quality Assurance – Ensure all shared data is accurately formatted and reflects the reality of our media activity across all platforms.
• Performance Interpretation and storytelling – Translate model results into a clear narrative regarding which channels are over‑ or under‑performing, and where the opportunity for growth lies.
• Agency partner – Act as the supporting daily contact for our econometrics agency, managing their workflow, ensuring they adhere to briefs, and challenging their recommendations when they don’t align with business needs. Champion their work internally and ensure engagement with the output.
• Technical Translation – Collaborate with strategists and analysts to translate ambitious ideas from Channel Leads 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.
• Backlog Prioritisation – Own the deployment of the measurement roadmap and decide which tests or model updates are most urgent based on the upcoming media calendar and broader business priorities.
• The “Knowledge Bank” – Maintain the central Test & Learn Log, documenting every outcome so that lessons learned are never lost and are actively used to programme the following month’s media plan.

Qualifications

• Multi‑channel knowledge – Proven experience working across multiple media channels.
• Measurement Frameworks – Proven experience with Marketing Mix Modeling, Multi‑Touch Attribution and Incrementality Testing.
• AdTech/MarTech Stack – Familiarity with the plumbing – how pixels, APIs and Clean Rooms function to collect data.
• Vendor Management – Experience managing relationships with third‑party measurement partners.

Key Criteria

• The “Translator” Mindset – Understand the fundamentals of marketing measurement and analytics (significance, incrementality, coefficients) but speak the language of a Media Planner with multi‑channel understanding.
• Operational Grit – Be a “doer” by nature, getting into the weeds of a spend file to ensure the data is 100 % correct before it reaches the analysts.
• Project Management Skills – Highly organised and capable of managing multiple workstreams between different teams with competing deadlines.

Experience

You likely have demonstrable experience within a media business, either agency (Data/Analytics/Planning/Transformation) or an in‑house effectiveness operations role. Ideally you also have experience with both paid and owned media, with an ability to evidence the nuances in their measurement challenges.

Flexible Working

Flexible working with a range of options.

Benefits

• Generous holiday allowance – plus you can buy more.
• Annual bonus opportunity.
• Competitive pension contribution.
• Save as you earn – with an opportunity to buy ITV shares.
• Wellbeing and volunteering days plus a wide range of opportunities to help you live a balanced and healthy life.
