Founding Full Stack Engineer

About the Role

This is a founding engineering role at a consumer health and wellness company sitting at the intersection of AI and ecommerce. You will own the entire engineering function, from a near-term membership platform MVP to a React Native consumer app and LLM-powered automation tooling, working directly with company leadership to move fast and build right.

What You'll Do

• Build and launch a consumer membership web application on Shopify and Recharge, then own ongoing maintenance and improvements after launch.
• Monitor and optimize page speed, app performance, and third-party script and pixel behavior across the storefront.
• Keep tracking and consent tools properly configured and compliant with privacy regulations such as CPRA.
• Own engineering architecture, stack choices, security decisions, vendor and contractor selection, and the databases underpinning the membership platform.
• Lead development of a consumer-facing React Native app from the ground up, with iOS as the first priority.
• Build LLM-powered agents and internal tools that run unattended in production, with evaluation frameworks, monitoring, and human-in-the-loop safeguards.
• Leverage AI, automation, and low-code tools to reduce manual operational work and improve execution speed across all functions.
• Tackle high-priority, ad-hoc problems directly with the CEO, moving fluidly between product and infrastructure decisions.

What We're Looking For

• 3 or more years of full-stack engineering experience shipping consumer products to production, with 5 to 10 or more years of overall software engineering experience preferred.
• Strong proficiency in TypeScript and React, with shipped production applications to demonstrate it.
• Proficiency in Python or Node.js with a track record of writing fast, reliable code.
• Hands-on experience with the Shopify platform and Recharge integration.
• Experience building and shipping consumer-facing React Native applications, ideally iOS-first.
• Demonstrated expertise in web performance optimization, including page speed, bundle size, and third-party script management.
• Experience implementing privacy compliance tooling such as consent management and CPRA or GDPR data handling.
• Comfort making architectural and security decisions independently with minimal guidance.
• Familiarity with AI-powered development tools, LLM agent frameworks, and automation workflows is a strong plus.
• A degree in engineering, computer science, mathematics, or equivalent demonstrated experience shipping software products.
