• AI-Native Engineering: Demonstrated, day-to-day fluency building with AI coding agents, such as planning with agents, reviewing their output, and creating custom skills or tooling

• Product Judgment: Sound instincts for user experience, and the ability to turn half-formed product requirements into well-scoped technical solutions
