Job Description
Purpose
We are seeking a highly experienced Linguistics professional consultant to serve as a consultant on AI training data projects for leading AI model builders and enterprises. Your focus will be to define success criteria, review outputs, and provide targeted guidance to improve quality and speed — directly contributing to the successful delivery of domain‑specific annotated datasets that meet the highest technical standards. You will be engaged on specific projects with clearly defined deliverables, milestones, and end dates.
Components
Define domain‑specific quality success metrics (e.G., accuracy of transcription, consistency in linguistic annotation schemes, phonetic transcription accuracy, adherence to grammatical frameworks, correct use of linguistic markup standards such as IPA or Universal Dependencies).
Develop project‑specific SOPs, QA rubrics, and reference materials for the specific purpose of meeting client technical standards.
