A Note on AI
You donāt need deep AI expertise for every role, but we do expect every Notino to be intellectually curious, drawn to tinkering and discovery, and excited to use AI as a real collaborator in their work. For some roles, AI fluency is a core requirement ā when thatās the case, we'll say so explicitly in the qualifications. People who thrive here donāt treat AI as a novelty. They use it to think better, and make their work easier for others to build on.
