Founding full-stack growth Engineer

Description

You'll own the company's growth engine, supporting our mission by helping more patients discover the company and turn to it for their day-to-day primary care needs. Landing pages, onboarding funnel, experimentation, attribution, and lifecycle messaging all belong to you. You'll work across the entire funnel - from the first ad impression or search result, through signup and onboarding, into first chat, subscription and long-term retention. You'll write the code, ship the pages, wire the events, run the tests, and read the results yourself. You'll partner closely with our clinical and compliance teams to make sure every page, claim and experiment is medically accurate and HIPAA-safe.

Your responsibilities

Acquisition and conversion surfaces:

Ship programmatic and SEO-driven page systems for condition, medication and geo intent Integrate paid ad platforms with our attribution stack so every channel's true contribution is measurable Build and iterate high-velocity landing pages and funnels in React + TypeScript Own patient acquisition and onboarding end to end

Product-led growth:

Build in-product growth loops — activation nudges, referrals, sharing and re-engagement surfaces Design onboarding that gets patients to first real value fast, then to habitual use Design, build and launch experiments and MVPs autonomously — from hypothesis to shipped test to readout, without waiting to be told what to try Turn patient behavior signals into personalized in-product prompts, with clinical review in the loop

Experimentation and attribution:

Own the experimentation platform end to end — assignment, exposure, guardrails, readouts Instrument the funnel in Amplitude and keep the event taxonomy trustworthy

Lifecycle:

Partner with the clinical team to keep patients engaged with the company over the long term and realize better health outcomes Build event-triggered lifecycle journeys across onboarding rescue, reactivation and re-engagement Own the CRM surfaces — email, SMS and in-product notifications — and the logic that decides who hears what, when
