• Oversee mobile and web delivery using React Native for iOS and Android, alongside React, including handling App Store, Google Play, and Stripe subscriptions.

• Apply product sensibility to enhance mobile and web user experience (UX).

• Convert technical decisions into understandable language for the founder and clinical team.

• Plan tasks, seek approval on direction, execute independently, and report on outcomes.

• Establish safety thresholds and crisis management systems with legal and clinical approval.

• Report directly to the non-technical founder and oversee the engineering function from start to finish.

⛳️ Requirements

• Established experience in delivering LLM-based products to production: prompt architecture, conversation state machines, RAG/retrieval, evaluations, moderation, and safety handling—not merely API calls.

• Solid expertise in React Native and React: able to deploy and debug on both iOS and Android, including in-app purchase flows on both platforms and Stripe on the web.

• Demonstrated commitment to AI-first development practices: daily utilization of agentic coding tools, with the discernment to review and take ownership of their output.

• Independent operator: proven history of managing a product or significant system from inception to completion with minimal technical oversight; excellent written communication skills for a non-technical founder.

• Attention to sensitive data: experience (or a serious commitment) to privacy, security, and access controls regarding personal and health data.

• Familiarity with mental health, health tech, or other regulated/safety-critical consumer products.

• Experience in taking over a codebase from an agency or departing team.
