Founding Full Stack Engineer
Summary
Founding full stack engineer at an AI-powered health and wellness ecommerce startup, owning the entire technical surface: launching a membership web app on Shopify/Recharge, later leading a React Native iOS app, and building LLM-powered internal agents. Core stack is TypeScript/React with Python or Node.js.
About the Role
This is a founding engineering role at an AI-powered health and wellness ecommerce startup, where you will own the entire technical surface: from a membership web app launch to a consumer mobile app and the LLM-powered agents that run internal operations. The role is intentionally broad and offers maximum ownership for an engineer who has already shipped products to real customers.
What You'll Do
Build and maintain a membership web application on an existing Shopify and Recharge stack, targeting a near-term launch milestone.
Monitor and optimize storefront page speed, app performance, and third-party script and pixel behavior.
Keep tracking and consent tooling properly configured and compliant with privacy regulations such as CPRA.
Own engineering architecture, stack choices, security, vendor and contractor decisions, and the databases behind the membership platform.
Lead development of a React Native consumer app (iOS first) once the membership MVP is live.
Build LLM-powered agents and internal tools designed to run unattended in production, with evals, monitoring, and human-in-the-loop checkpoints where needed.
Use AI, automation, and low-code tools to reduce manual work and accelerate execution across all business functions.
Partner closely with the CEO on high-priority, ad-hoc problems, moving fluidly between product and infrastructure decisions.
What We're Looking For
Demonstrated track record of shipping a consumer-facing product in production to real users.
Strong proficiency in TypeScript and React.
Proficiency in Python or Node.js, with a history of shipping fast and reliable code.
Hands-on experience with Shopify and Recharge.
Experience building consumer-facing React Native apps, with an iOS-first mindset.
Experience shipping web apps with strong performance optimization.
Familiarity with AI-powered tools, LLM integrations, and automation workflows.
Bachelor's degree in engineering, science, or mathematics, or equivalent demonstrated experience through shipped work.
Compensation & Benefits
Base salary: $130,000 to $160,000 USD annually.

On-site in San Francisco, CA, United States.
