Based in Mexico City but fluent in Castilian Spanish? This is your opportunity. This is meticulous, rewarding work for people who notice what others miss — a misheard syllable, a dropped accent, a timestamp that's a fraction of a second off.
This is a fully remote, adaptable contract role. No prior AI experience needed — just native or near-native Castilian Spanish fluency, excellent listening skills, and a commitment to precision.
