Job Description

Principal Data Scientist

AdRoll, a division of NextRoll

• Lead the design, development, and deployment of ML models that predict and influence customer behavior — including churn, retention, activation, lifetime value, and lifecycle transitions. • Build behavioral segmentation frameworks, uplift models, and propensity scoring used across product, lifecycle marketing, and account strategy. • Drive insights for core product areas (audience targeting, measurement, bidding, onboarding, campaign performance) using a mix of causal inference, predictive modeling, and experimentation. • Own end-to-end analytics for key initiatives: partner with Product to define success metrics, guide instrumentation, design experiments, and quantify impact. • Design, build and deploy rigorous and statistically sound models and systems that help customers understand causal effects of their marketing strategies. • Influence product roadmaps using quantified opportunity sizing, behavioral funnel analysis, and deep dives into customer usage patterns. • Collaborate with Data Engineering and ML Platform teams to build scalable pipelines, datasets, and model operationalization workflows. • Act as a technical mentor for the broader analytics and data science team; elevate scientific rigor, model quality, and best practices.

Job Requirements

  • 9+ years of experience in data science, machine learning, or advanced analytics roles, ideally in a SaaS, AdTech, or MarTech environment.
  • Knowledge of and experience in implementing marketing data science models such as predictive models (churn, retention, LTV), advanced segmentation and behavioral clustering.
  • Skilled in causal inference techniques (e.g., synthetic controls, DiD, uplift modeling, geo-experiments, CUPED) and experimentation frameworks.
  • Knowledge of ad ecosystems (RTB, attribution, identity graphs, bidding strategies, pixel events, campaign optimization, incrementality).
  • Strong fluency in SQL and Python, with hands-on experience building and shipping production-grade ML models.
  • Proven track record partnering with Product to define metrics, run experiments, and shape product strategy.
  • Excellent data storytelling abilities — able to translate complex patterns into clear, action-oriented recommendations for cross-functional partners.
  • Comfortable navigating ambiguous problem spaces and driving long-term analytical strategy.
