3+ years of experience in data labeling, RLHF/SFT, or AI evaluation delivery - you have shipped real annotation or evaluation projects at a data labeling company (Scale, Surge, Mercor, Snorkel, Handshake, Centific, Labelbox, SuperAnnotate, or similar) or inside an AI lab. We build high-quality, expert-generated datasets that train and evaluate frontier AI systems - spanning domain eval sprints, custom data solutions, model behavior audits, agentic RL environments, and domain QA-as-a-service.
