The Role

We’re seeking a Senior Growth Engineer to drive technical initiatives that accelerate our user acquisition, engagement, and retention. You will work at the intersection of engineering, product, and marketing to build, measure, and scale systems that optimize our growth funnel end‑to‑end — from awareness through activation and retention. Your work will bridge technical depth with a growth mindset : shipping experiments rapidly, optimizing data‑driven systems, and ensuring that every part of the user journey is measurable, performant, and privacy‑safe. You’ll collaborate closely with marketing, data, and product teams to turn insights into scalable growth levers.

Who You Are

You’re an engineer with a growth brain — data‑fluent, experimentation‑minded, and obsessed with driving measurable outcomes. You thrive in high‑velocity environments, love collaborating across teams, and can toggle seamlessly between shipping production code and designing data pipelines that feed growth intelligence.

You Will

• Prototype and launch growth features – rapidly build and iterate on onboarding flows, referral programs, landing pages, and other high‑impact experiments that drive measurable improvements in conversion and engagement.
• Build and scale growth systems – develop and maintain the experimentation, attribution, and analytics infrastructure that powers our user acquisition, activation, and retention efforts.
• Implement and optimize CRM integrations – own the technical setup of our lifecycle marketing stack (CRM platform and downstream channels), ensuring campaigns are data‑driven and automated across push, email, and in‑app messaging.
• Instrument and maintain data pipelines – ensure accurate, privacy‑safe event tracking and identity resolution across web, mobile, and backend systems (Amplitude, Salesforce, Webflow, CRM).
• Collaborate cross‑functionally – partner with product, marketing, and data teams to define hypotheses, deploy experiments, and translate insights into product and channel improvements.
