Marketing Science Lead

As the Growth Marketing Science Lead, you will be the architect of our "Test and Learn" ecosystem.

With an annual spend exceeding $100M, your mission is to ensure every dollar is optimized through rigorous statistical validation. You will translate complex data into high-growth strategies for our search and paid social teams, ensuring we aren't just spending, but scaling intelligently.

Responsibilities

• Experimentation Roadmap: Design and lead a high-velocity A/B and multivariate testing roadmap across channels, campaign types, ad creatives and audience segments.
• Strategic Guidance: Serve as the "strategic pulse" for the Paid Marketing team. Provide data-backed briefs that tell Channel Managers exactly where to pivot spend based on test winners.
• Opportunity Discovery: Go beyond standard reporting to "mine" data for untapped growth levers. Identify patterns that haven't been scaled and propose the business case for expansion.
• Platform Alpha & Best Practices: Stay at the bleeding edge of ad platform capabilities (Google, Meta, LinkedIn). Experiment with "alpha/beta" features (e.g., Value-Based Bidding, PMax experimentation) to ensure our stack is consistently ahead of industry benchmarks.
• Advanced Attribution: Continuously refine our multi-touch attribution (MTA) and Media Mix Modeling (MMM) models to measure the incremental impact of non-linear B2B buyer journeys.
• Marketing Data Infrastructure: Partner with Analytics Engineering to build clean, scalable data models in Snowflake (via dbt) that specifically track experiment lift and incrementalities, and present their performance metrics in dashboard.

Desired Skills and Competencies

• 5+ years in a Data Analytics or Growth Marketing role, ideally within a high-spend B2B environment.
• Proficiency in SQL, Looker, Snowflake or comparable stack.
• Deep understanding of experimentation methodology, sample size calculation, p-values and confidence intervals.
• Familiarity with the B2B sales funnel
• A "growth mindset" - curious and eager to learn
