UX Writer / Content Designer
Designs the interface's words: microcopy, flows, error messages and product voice — language as a design material.
Why this hire matters.
In a product, every word is a design decision: an ambiguous button label drops conversion, a cryptic error message generates support tickets, a poorly written onboarding loses users no visual redesign will recover. The UX writer treats language with the same rigor a designer treats pixels — testing included. Their impact is measurable: flow completion rates, tickets avoided, feature adoption. The rise of conversational interfaces and AI agents sharply revalues this skill: an AI product's tone, clarity and verbal behavior are literally written. In France the role remains rare and often absorbed by design or product — hiring it means getting ahead on a common blind spot.
