About the role

Responsibilities

  • Design and analyze marketing experiments across paid, lifecycle, and content channels; optimize CAC, LTV, and ROAS
  • Build multi-touch attribution and marketing mix models to understand what's driving growth
  • Synthesize customer signals — support tickets, social, reviews, CSAT — into automated intelligence that reaches the teams who need it
  • Build churn and retention models to identify at-risk users and inform lifecycle intervention strategies
  • Define and maintain customer segmentations and personas that drive targeting, messaging, and product decisions
  • Build the analytical foundation for Voice of the Customer — connecting qualitative feedback signals to quantitative behavior data at scale
  • Detect emerging product issues and bugs faster by surfacing support signal early enough to shape engineering priorities
  • Optimize automation and deflection to reduce support load and improve self-serve resolution rates
  • Build the measurement foundation to fully optimize ROI across all support activities
  • Use LLMs and agentic workflows to analyze unstructured data at scale and automate recurring analysis
  • Create automated reporting that put key metrics to inform the company

Required Skills and Experience

  • 6+ years of experience in data science with a focus on marketing, growth, or customer analytics
  • Strong SQL skills and experience with large-scale event-level user behavior data; experience designing ETL workflows using dbt
  • Proficiency in Python and data science libraries (pandas, scikit-learn, statsmodels, etc.)
  • Experience designing and analyzing A/B tests with statistical rigor (sample sizing, significance testing, causal inference)
  • Experience building dashboards and visualizations (Hex, Looker, Tableau, Mode, or similar) — ideally automating them
  • Demonstrated experience using LLMs/AI tools in analytics workflows — not just prompting, but building automated systems
  • Track record of partnering cross-functionally with Marketing, Product, Engineering, Support, and Revenue/Sales teams

Preferred Qualifications

  • Experience with modern data stack (dbt, BigQuery, Snowflake, Fivetran, Segment, etc.)
  • Background in growth analytics, marketing analytics, or conversion rate optimization at a SaaS or PLG company
  • Experience with marketing technology platforms (Google Analytics, Segment, Iterable, Salesforce)
  • Experience with attribution modeling, marketing mix modeling, or incrementality testing
  • Experience analyzing unstructured customer data (support tickets, reviews, social mentions) using NLP or LLM-based approaches
  • Understanding of PLG motions and self-serve conversion funnels
  • Experience with support analytics, CSAT analysis, or customer experience measurement

Bonus Points

  • Experience analyzing freemium or usage-based pricing models
  • Understanding of developer tools, collaborative coding environments, or technical products
  • Experience with causal inference methods (difference-in-differences, synthetic control, propensity score matching)
  • Experience building AI agents or automated analytical pipelines using LLM APIs
