Job Summary

Own growth funnel metrics and experiments to drive activation, retention, and LTV with hands-on modeling and clear storytelling for the product. Build activation, churn, and conversion models and turn event data into actionable insights, surfacing high-leverage changes for the team and founders.

  • Growth ownership: funnels, experiments, and data models that tie to decisioning
  • Analytics execution: turning messy events into trusted analysis and dashboards
  • Cross-functional bets: partner with growth, product, and founders to size and prioritize high impact opportunities

Job Description

Responsibilities

  • Own the metrics that define our growth funnel: signup, activation, conversion, retention, and how they connect
  • Design and run experiments (A/B tests and beyond), and read them honestly, including when the answer is "no effect"
  • Build the models that matter for growth: activation prediction, churn and retention, conversion propensity, and LTV
  • Turn messy product and billing events into clean, trusted analysis (we run on PostHog and a warehouse)
  • Find the leverage: the few places where a small change in the funnel produces an outsized result, and size the opportunity before we build
  • Make your work legible with clear metrics, dashboards, and writeups the whole team can act on
  • Partner with growth and product day to day, and with the founders on the bets that matter

Requirements

  • Have several years in product or growth data science, ideally at a product-led or consumer company with real scale
  • Are genuinely hands-on: you write your own SQL and Python, build your own models, and don’t need a platform team to get answers
  • Know experimentation cold, both the statistics and the judgment, and can tell a real effect from noise
  • Think in funnels and systems, and connect a metric to the decision it should drive
  • Communicate in plain language, and aren't afraid to deliver an inconvenient finding
  • Have built data models or pipelines when the job needed it (dbt, warehouse), even if analysis is your main game
  • Care about AI and creative tools, ideally as a ComfyUI user
  • Like a small, intense team: high ownership, low ego, fast clock
  • Are in SF or ready to be

Preferred

  • You've stood up an experimentation program or an analytics stack from scratch
  • You're comfortable with PostHog, dbt, or similar tools
  • You can point to analysis that changed what a company did, not just what it knew

Benefits

  • company-sponsored Medical, Dental, and Vision (up to 100% coverage)
  • unlimited PTO
  • daily catered lunch and dinner
  • your choice of equipment
  • an unlimited budget for AI tools
