Prolific runs a participant-sourcing platform that supplies human data for AI developers and researchers, built on Python, Django REST Framework, Vue and TypeScript across AWS, GCP and Azure. The hiring mix leans heavily toward data and research roles rather than engineering, and projects such as RLHF, payroll-task benchmarks and dataset auditing suggest much of that hiring is domain-expert work feeding AI model evaluation.
