The Challenge
Summer Health is solving a massive blind spot in parental health awareness-detecting and acting on critical deficiencies like low ferritin that pediatricians miss. You'll own the entire growth flywheel from discovery through referral, shipping experiments weekly with AI agents as your co-pilot.
Your Mission
Build and launch acquisition channels (paid social, community presence, organic) that reach health-conscious parents; measure CAC and traffic quality
Map and optimize the signup-to-first-blood-draw funnel; reduce drop-off rate by 25%+ through activation flows and dynamic content
Implement PostHog instrumentation across all critical user journeys; establish baseline metrics for acquisition, activation, and retention
Ship 2-3 AI-powered growth experiments (personalized nudging, predictive churn, dynamic onboarding) using agents daily
Build a referral engine that turns post-results users into acquisition channel; measure viral coefficient and referral CAC
Achieve 50%+ improvement in signup-to-completion rate through lifecycle retention and post-results experience redesign
Establish and own a weekly experiment cadence: test, ship, measure, kill or double down in 5-7 day cycles
Develop AI-driven personalization layer that increases engagement and reduces churn for high-intent segments
KPIs You'll Own
Customer Acquisition Cost (CAC)
Track cost per parent acquired across all channels; optimize mix toward lowest CAC channels with retained users.
Signup-to-Completion Rate
Measure % of parents who start questionnaire and complete first blood draw order; primary activation funnel metric.
Referral Rate / Viral Coefficient
Count parents who refer other parents; track if viral loop is self-sustaining (coeff > 1).
Churn/Retention by Lifecycle Stage
Measure retention post-results, post-action, and post-repeat test; identify where parents disengage and intervene.
AI Experiment Velocity
Track # of AI-powered experiments shipped per month; speed is the constraint at this stage.

Benefits & Perks
Company Intelligence
Summer Health is building a parental health data platform that detects critical deficiencies (like low ferritin) that doctors often miss. The company is creating a system where parents go from noticing symptoms → getting diagnosed → taking action → becoming advocates who refer others.
Culture
Extreme ownership, bias to shipping, AI-native, mission-driven, no corporate fluff
Is This Role For You?
- You've shipped growth experiments that actually moved needle-and learned from ones that didn't
- You're using AI coding agents daily and already building AI-powered features or growth loops (not just testing agents)
- You have public body of work (GitHub, blog, shipped product) that shows you build when no one assigns work
- You genuinely care about family health beyond resume padding and can own ambiguous, end-to-end processes solo
- You're a growth marketer who runs A/B tests on button colors-this needs full-stack growth engineering with shipping velocity
- You don't use AI agents daily or haven't shipped anything with AI; the pace here assumes agents are your workflow, not optional
- You need detailed specs and hand-holding; this role demands comfort owning processes end-to-end with ambiguity

About Growth Marketing roles
Growth marketers drive user acquisition, activation, and retention through data-driven experimentation. They sit at the intersection of product, data, and marketing — running A/B tests, building funnels, and scaling what works.
