About the role

Comfy is looking for our first dedicated product and growth data scientist.
Millions of people use ComfyUI, and we're turning that reach into a real business.
We need someone who can tell us what's actually happening inside the funnel, find where the leverage is, and prove what moves the numbers.

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
Find the leverage: the few places where a small change in the funnel produces an outsized result, and size the opportunity before we build
Partner with growth and product day to day, and with the founders on the bets that matter
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
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
ComfyUI https://www.comfy.org/ is the world's leading visual AI platform, an open, modular system to build AI workflows.

Make your work legible with clear metrics, dashboards, and writeups the whole team can act on
You Might Be a Fit If You
Have several years in product or growth data science, ideally at a product-led or consumer company with real scale
Know experimentation cold, both the statistics and the judgment, and can tell a real effect from noise
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

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