• Make decisions about architecture, databases, security, technology choices, and vendors.

• Lead development of a consumer-facing React Native app, with an iOS-first focus.

• Build and operate LLM-powered agents and internal tools with monitoring, evaluations, and human oversight where appropriate.

• Create scripts, automations, and workflows that reduce manual work across the business.

• Work directly with leadership on high-priority product and infrastructure needs.

What We're Looking For

• At least 5 years of full stack engineering experience, including shipping consumer products to production.

• Strong proficiency in TypeScript and React, plus production experience with Python or Node.js.

• Hands-on experience with Shopify and Recharge, and a record of optimizing web application performance.

• Experience building consumer-facing React Native applications, preferably with an iOS-first approach.

• Knowledge of architectural and security decisions, privacy compliance, and consent management.

• Experience with AI tools or production automation is valuable, especially LLM agents with monitoring and evaluation practices.

• A bachelor's degree in engineering, computer science, mathematics, or a related field, or equivalent experience shipping software products.
