Role Description

As the Director, Data Science & Measurement, you will be the primary analytical mind and strategic architect behind our advanced media attribution, experimentation, and business science methodologies. This role is designed for a heavyweight statistician and media measurement expert who thrives on solving the "what worked and why" for major brands.

While you will collaborate closely with our dedicated internal Data Engineering and Infrastructure teams—who build and maintain our cloud pipelines—you will own the mathematical frameworks, model designs, and causal inference methodologies. You will act as a senior leader, serving as the crucial bridge who translates complex statistical outputs (like MMM, MTA, and lift studies) into high-level strategic narratives and multi-million-dollar budget optimization recommendations for modern CMOs and CFOs.

• Location: Montreal, QC (Open to Toronto or Vancouver for the right fit)
• Core Focus: 70% Statistical Modeling, Attribution Methodology & Experimental Design; 30% Client Consulting, Narrative Strategy & Team Mentorship.

Key ResponsibilitiesAdvanced Attribution & Econometric Modeling

• Methodology Ownership: Lead the theoretical design, validation, and mathematical execution of custom Marketing Mix Models (MMM), Multi-Touch Attribution (MTA), and customer Path-to-Conversion frameworks.
• Unified Measurement Strategy: Champion a "Unified Measurement" approach, combining macro-level MMM econometric trends with micro-level digital attribution signals to give clients a singular source of truth.
• Advanced Feature Engineering & Design: Determine the data requirements, adstock transformations, and saturation curve variables needed for accurate modeling, directing data engineers on how to prepare these schemas.

Experimentation & Causal Inference

• Testing Frameworks: Architect randomized control trials (RCTs), matched-market tests, and geo-lift studies to establish true incrementality and validate marketing models.
• Model Calibration: Use test-and-learn results and lift studies to continuously calibrate and ground MMM/MTA models, stripping out correlation and proving true causal media ROI.

Client Consulting & Strategic Storytelling

• Strategic Translation: Turn highly complex mathematical outputs, coefficient shifts, and statistical variances into clear, visual, and highly compelling business recommendations.
• Budget Optimization: Guide clients on optimal media mix scenarios, flighting strategies, and cross-channel budget reallocations based on model predictions.
• New Business & Growth: Serve as the measurement subject matter expert during high-profile agency pitches, articulating our advanced attribution capabilities to prospective client stakeholders.
• Team Mentorship: Direct and mentor a growing team of media analysts and marketing scientists, cultivating deep methodological expertise and client-ready presentation skills.

Qualifications & RequirementsExperience

• 7+ years of professional experience in marketing science, econometrics, data science, or advanced media analytics.
• 3+ years of experience specifically focused on designing and running attribution models (MMM/MTA) and designing lift/incrementality experiments.
• Strongly Preferred: Direct experience working within a Media Agency, AdTech firm, or marketing consultancy.

Technical & Mathematical Mastery

• The Math: Deep theoretical and practical knowledge of linear/non-linear regression, Bayesian statistics, time-series analysis, adstock modeling, and causal inference.
• The Tools: Hands-on proficiency using Python or R for statistical modeling and data manipulation, alongside advanced SQL to extract and aggregate data.
• The Ecosystem (Collaborative): Broad familiarity with Google Cloud Platform (BigQuery) and Web/App Analytics (GA4/Firebase schemas)—not to build the pipelines, but to know exactly what data signals are available for your models.
• Data Visualization: Competency in translating model outputs into clear visual stories using tools like Looker Studio, Tableau, or PowerBI.
