The Challenge

JD Finish Line is building a world-class growth analytics function from the ground up. You'll own the quantitative engine that drives millions in annual marketing spend—building MMM, attribution, and predictive models that move the needle on CAC and CLV.

Your Mission

First 3 Months
1

Audit current analytics stack (Looker, BigQuery, GA4, Meta, Google) and propose a unified data architecture for cross-channel measurement

2

Design and scope a Market Mix Modeling (MMM) framework to inform quarterly budget allocation across Paid, Owned, and Earned channels

3

Launch first geo-lift test on a major paid campaign to establish ground truth on incrementality vs. baseline attribution models

4

Build churn prediction model in collaboration with CRM/Retention team to feed propensity scores into Braze

By 6 Months
1

Deploy production MMM model with quarterly refresh cycle advising VP on media mix optimization and budget reallocation

2

Implement multi-touch attribution (MTA) framework replacing last-click reporting; document 15%+ CAC efficiency gains vs. previous model

3

Operationalize CLV and Next-Best-Action predictive models feeding real-time segments into Braze for 1-to-1 personalization at scale

4

Establish quarterly incrementality testing cadence (3+ lift studies) across Meta, Google, and brand campaigns; publish insights playbook

KPIs You'll Own

Blended Customer Acquisition Cost (CAC)

Track month-over-month CAC across paid channels; optimize bid strategy and budget allocation based on MMM and MTA insights.

Customer Lifetime Value (CLV) by Cohort

Predict and monitor CLV across acquisition channels and customer segments; feed into paid media targeting and retention prioritization.

Churn Rate & Retention Lift

Measure impact of predictive churn models and personalized retention campaigns powered by propensity scoring.

Incrementality (True Causal Impact)

Validate paid media effectiveness through geo-lift, DDA, and holdout tests; quantify incremental revenue vs. baseline attribution.

Model Accuracy & Lift vs. Baseline

Track MTA, MMM, and propensity model performance; measure lift in decision-making speed and confidence vs. legacy reporting.

Is This Role For You?

For You If
  • You've built or owned MMM, MTA, or incrementality testing frameworks in a production environment (retail, ecommerce, or high-volume digital preferred)
  • You're fluent in SQL, Python/R, and statistical modeling; comfortable translating math into actionable strategy for non-technical stakeholders
  • You thrive as a strategic partner, not just a reporter—you want to shape marketing strategy through data architecture, not just react to requests
  • You've operationalized predictive models (churn, CLV, propensity) in marketing automation platforms or CRM systems at scale
Won't Work If
  • You're looking for a pure reporting/BI analyst role—this is a strategic modeling and growth engineering position with high ownership expectations
  • You lack hands-on experience building statistical models (MMM, MTA, propensity scoring) or incrementality testing frameworks from scratch
  • You're not comfortable taking ownership of foundational work—this is building the analytics function, not inheriting a mature one

Interview Process

1

Initial Screening

Recruiter call to assess background in marketing science, modeling, and growth analytics; discuss specific projects (MMM, lift tests, attribution)

2

Technical Deep Dive

Conversation with VP or Head of Analytics on statistical modeling approach, tool stack decisions, and how you'd architect measurement for their organization

3

Case Study / Take-Home

Short assignment: Design an MMM or incrementality testing framework for a sample marketing scenario; walk through methodology and recommendations

4

Executive Round

Conversation with VP, Digital Marketing to discuss strategic vision, partnership style, and how you'd operationalize insights across teams
