Marketing Effectiveness Lead, Urban Outfitters Europe
Who you are
Proven hands-on experience with MMM — either building models in-house or managing vendor relationships
Strong understanding of MTA platforms and their limitations
Experience building LTV and cohort analysis frameworks in an ecommerce context
Ability to translate complex quantitative outputs into clear commercial recommendations
Confident working with both brand and performance teams — comfortable in a briefing room and a data warehouse
Experience owning reporting across a multi-channel marketing function
Desirable
Background in retail, fashion, or DTC ecommerce
Experience working with European multi-market data (currency, seasonality, market mix variation)
Familiarity with incrementality testing methodologies (geo-lift, holdout groups)
Exposure to media agency planning and buying cycles
SQL or Python skills for data manipulation — you don't need to be an engineer but being able to interrogate data directly is a strong plus
What the job involves
Urban Outfitters' European digital business is growing across paid, organic, and social channels, and we need someone who can make sense of all of it
This role exists to bring rigour and strategy to how we measure, plan, and allocate our marketing investment across both brand and performance
You will be the go-to person for understanding what's working and why — building the measurement frameworks, running the models, and translating complex data into clear budget recommendations
You'll sit at the intersection of brand and performance, ensuring neither operates in a silo and that every pound spent is accountable to a commercial outcome
Own and evolve the measurement framework across all marketing channels — paid, organic, social, brand, and performance
Lead the implementation and ongoing operation of Marketing Mix Modelling (MMM) and Multi-Touch Attribution (MTA) — either in-house or via vendor partnership
Run incrementality testing to validate model outputs and build confidence in spend decisions
Ensure measurement approaches are privacy-compliant and future-proofed against a cookieless environment
Design and own the single source of truth for marketing performance across the European business
Report on brand health metrics — awareness, consideration, share of voice — alongside performance KPIs
Build and maintain LTV reporting by channel and cohort, surfacing insights that connect acquisition investment to long-term customer value
Translate model outputs into clear, executive-ready narratives for senior stakeholders and Finance
Use MMM and MTA outputs to inform and challenge channel investment decisions — where to spend, where to pull back, and where the untapped opportunity sits
Partner with channel leads across paid social, paid search, affiliates, email, and organic to ensure budget allocation is grounded in effectiveness data
Own the marketing efficiency metrics — ROAS by cohort, CAC:LTV — and use them to drive continuous improvement in spend efficiency
Contribute to annual and seasonal budget planning cycles with data-backed scenario modelling
Work closely with Brand and Creative teams to ensure brand investment is measurable and included in effectiveness modelling
Partner with Finance to align on methodology, build finance-level confidence in measurement outputs, and support budget sign-off
Collaborate with Data/BI to maintain clean, reliable data pipelines that underpin the measurement stack
