• 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.

• 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.
