About the Role

This is a founding engineering role at a consumer health and wellness startup, where you will own the entire engineering function across a membership platform, consumer app, and internal tooling. You will be the first dedicated engineer, working closely with leadership to ship fast and make high-impact architectural decisions from day one.

What You'll Do

• Build and launch a consumer membership web application on Shopify and Recharge, then own ongoing maintenance and improvements.

• Monitor and optimize page speed, app performance, and third-party script behavior across the storefront.

• Keep tracking and consent tooling properly configured and compliant with privacy regulations such as CPRA.

• Own engineering architecture, stack choices, security, vendor selection, and database decisions for the membership platform.

• Lead development of a consumer-facing React Native app from the ground up, prioritizing iOS.

• Build LLM-powered agents and internal tools that run unattended in production, with evals, monitoring, and human-in-the-loop safeguards where needed.

• Leverage AI, automation, and low-code tools to reduce manual operational work across all functions.

• Work directly with the CEO to tackle high-priority, fast-moving product and infrastructure problems.

What We're Looking For

• 3 or more years as a full-stack engineer shipping consumer products to production, with 5 to 10 or more years of overall experience preferred.

• Strong proficiency in TypeScript and React, with shipped production applications to show for it.

• Proficiency in Python or Node.js and a track record of shipping reliable code quickly.

• Hands-on experience with Shopify and Recharge integrations.

• Proven experience building and shipping consumer-facing React Native apps, iOS-first.

• Demonstrated expertise in web performance optimization, including page speed, bundle size, and third-party script management.

• Experience making architectural decisions around databases, security, and engineering stack choices.

• Experience implementing privacy compliance tooling, including consent management and CPRA or GDPR-related data handling.

• Familiarity with LLM-powered agents, AI automation tools, and evaluation frameworks.

• Degree in engineering, computer science, mathematics, or equivalent demonstrated experience shipping software products.
