Job Description
Growth Marketing Science Lead optimizing over $100M in marketing spend for a global payroll platform. Designing A/B tests and enhancing data models to drive growth marketing strategies.
Responsibilities:
- Design and lead a high-velocity A/B and multivariate testing roadmap across channels, campaign types, ad creatives and audience segments.
- Provide data-backed briefs that tell Channel Managers exactly where to pivot spend based on test winners.
- 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.
- Stay at the bleeding edge of ad platform capabilities (Google, Meta, LinkedIn). Experiment with "alpha/beta" features to ensure our stack is consistently ahead of industry benchmarks.
- Continuously refine our multi-touch attribution (MTA) and Media Mix Modeling (MMM) models to measure the incremental impact of non-linear B2B buyer journeys.
- 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.
Requirements:
- 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
Benefits:
- Stock grant opportunities dependent on your role, employment status and location
- Additional perks and benefits based on your employment status and country
- The flexibility of remote work, including optional WeWork access
