Lead Marketing Data Analyst
Opportunity
marketing channels: email, direct mail, and digital. This role sits at the intersection of marketing strategy, data, and technical execution. You will turn raw campaign and behavioral data into clear analysis that drives decisions at every level, from channel owners to the executive team.
Right now, the first priority is to understand performance before we optimize it. In your first year you will establish trusted, consistent performance baselines across channels, find where the data does not add up, and tell us what is working and what is not. As that foundation matures, the role grows into attribution, marketing mix, and scoring models that guide budget allocation and targeting.
Our data foundation is built by our data engineering team. You will be its most demanding user. You will query across sources to answer marketing questions, find the gaps and inconsistencies others miss, and tell the data team what needs to be tracked, modeled, or fixed so the next question is easier to answer.
This role is for someone whose edge is judgment. You know what to ask before you write the query, you notice when an answer does not add up, and you give the marketing team a recommendation they can act on. It is a hands-on, high-impact individual contributor role for someone who works independently in a fast-moving environment and is equally comfortable digging through a warehouse and presenting to senior leaders.
Responsibilities
Channel Performance Measurement & Analytics
Measure and report on performance across email, direct mail, and digital — defining the right metrics, building reporting, and surfacing what is working and what is not
Own digital analytics end to end, including event tracking and tagging strategy, and partner with engineering to ensure data is captured accurately across web and app properties
Build and maintain attribution and marketing mix models to quantify channel contribution and guide budget allocation across the marketing portfolio
Analyze paid channel performance — spend efficiency, ROAS, and incrementality — and translate findings into clear optimization recommendations
Decision support for performance marketing
Partner with channel owners to turn campaign goals into specific, testable questions, and answer them with analysis before launch, while campaigns are in flight, and after they close
Analyze channel mix, budget allocation, and pacing using CPM, CPC, CAC, conversion rate, and ROAS, and recommend where to shift spend
Profile audiences across multiple data sources to size and describe segments for targeting, and recommend who to reach and with what message
Analyze funnels and landing page performance from impression through registration to enrollment, and recommend conversion rate improvements
Data quality and the data foundation
Write complex SQL to explore, join, and reconcile data across the warehouse and martech platforms, and validate queries drafted with AI assistance
Question the data: find gaps, conflicting definitions, and tracking breaks, reconcile numbers across platforms, and raise issues with the specifics the data team needs to fix them
Define requirements for data engineering, including the events, facts, dimensions, and metric definitions needed to support attribution, mix modeling, and scoring in the future, and explain why each one matters
Document the metric definitions and logic the marketing team relies on
Data Science & Advanced Modeling
These responsibilities build on the measurement foundation above. Expect to start by evaluating and directing this work, and to take on more of the build as the data matures.
Own marketing mix modeling (MMM) end to end — building, validating, and refreshing models that quantify channel contribution, diminishing returns, and saturation to guide budget allocation
Develop propensity and other scoring models to predict member behavior — conversion, churn, and engagement — and operationalize scores to drive targeting, segmentation, and lifecycle marketing
Apply Bayesian network analysis and related probabilistic methods to model relationships between marketing drivers and outcomes, quantify uncertainty, and support causal and incrementality analysis
Partner with data engineering to productionize models, monitor performance over time, and ensure outputs are reliable, explainable, and decision-ready for leadership
Experimentation and testing
Design, run, and read A/B and multivariate tests, including sample sizing, significance, and interpretation, and recommend what to test next
Help establish testing standards and maintain a prioritized roadmap of experiments
Insights and communication
Present findings and recommendations to marketing leadership and the executive team in a clear, decision-ready way
Partner with marketing, engineering, data engineering, finance, and product to align on definitions, attribution, and measurement standards
Other duties as assigned
Qualifications
8+ years in marketing analytics, performance marketing analytics, data analytics, or a closely related field
Sound analytical judgment, shown by examples where you reframed a question, found a flaw in the data, or changed a decision
Proven experience measuring email, direct mail, and digital marketing performance, including channel mix, budget allocation, CPM, CAC, ROAS, and conversion rate optimization
Comfort writing and validating complex SQL against a cloud data warehouse (Snowflake preferred), with or without AI assistance. Data engineering is not part of this role.
Working knowledge of attribution, marketing mix modeling, incrementality, and paid channel analysis
Experience with scoring and predictive models, such as propensity models, marketing mix models, or Bayesian methods, and with applying them to real marketing decisions. Depth in at least one of these and a working understanding of the others.
Working knowledge of tracking and instrumentation (UTMs, pixels, tag managers, event taxonomy) and of data modeling concepts such as facts and dimensions, enough to specify requirements and spot problems
Solid understanding of A/B testing: experiment design, sample sizing, significance, and interpretation
Experience using AI tools such as Claude in analysis and reporting workflows
Excellent communication skills, with a track record of presenting analysis to senior leadership
