- Design agentic AI workflows, tool calling, structured outputs, and evaluation pipelines
- Establish engineering standards and architecture decisions
- Partner directly with the Founder on product strategy and execution

Who You Are

- 7+ years building production software
- Strong React Native experience shipping consumer mobile applications
- Full-stack engineering experience across frontend, backend, and infrastructure
- Production experience building AI-powered applications using Claude, OpenAI, Gemini, or similar frontier models
