Be the architect of marketing truth. We’re partnering with a globally recognised technology-led organisation on a senior marketing research contract at the cutting edge of marketing science. This role is for someone who doesn’t just report performance — they change how decisions are made. Your mission: help the organisation transition from correlation-based reporting to causal-based decision making, ensuring every marketing pound works harder, smarter, and with provable impact. You’ll sit at the intersection of Marketing Mix Modelling, Data Clean Rooms, and Experimental Design, stewarding a triangulated measurement framework that guides high-stakes investment decisions across the business.
What You’ll Be Doing
- Strategic Modelling & Budget Optimisation (40%)
- Translate complex Marketing Mix Model outputs (response curves, saturation, adstock) into clear, confident budget recommendations.
- Partner with Finance and Marketing leadership to defend budget shifts using marginal ROI (mROI).
- Build predictive models to simulate business outcomes across different economic and spend scenarios — acting as the early-warning radar for marketing performance.
- Data Clean Rooms & Advanced Analytics (30%)
- Act as analyst lead for Data Clean Room strategy, with a focus on Meta Advanced Analytics.
- Write and optimise advanced SQL to securely join hashed first-party data with platform exposure data.
- Move beyond generic lookalikes by designing high-value, precision audiences based on LTV, retention probability, and behavioural signals.
- Own the organisation’s Learning Agenda, defining a quarterly roadmap of hypotheses prioritised by business impact.
- Design and execute rigorous Conversion Lift and Brand Lift Studies, including power calculations, holdout design, and implementation oversight.
- Meta-analyse experimental results to codify best practices for Creative and Media teams.
- Educate stakeholders on the difference between vanity metrics (clicks, ROAS) and value metrics (incremental sales, profit).
- Communicate complex ideas simply — telling compelling stories with data.
What We’re Looking For
- Must Have
- A number of years experience in marketing science, market research, or advanced analytics.
- Advanced SQL skills (CTEs, window functions, join optimisation).
- Proven experience building or managing Marketing Mix Models.
- Strong understanding of Bayesian inference, adstock, and saturation curves.
- Experience with AI tools and/or process automation.
- Nice to Have
- Hands-on experience with Data Clean Rooms (Meta AA, AMC, ADH, Snowflake).
- Deep knowledge of hypothesis testing, confidence intervals, and bias.
- Ability to explain posterior distributions to a CMO as “updated beliefs.”
- Understanding of AdTech, paid media mechanics, ROAS vs CAC, and margin profiles.
- Confident, collaborative communicator who can influence senior stakeholders.
