Scale AI
Scale AI is a data-labeling and AI infrastructure company that powers training data for many frontier model labs and enterprise AI teams. Founded in 2016, Scale operates a global labeling workforce, builds tools for evaluation and red-teaming, and has pivoted toward a generative-AI data engine and enterprise GenAI deployments (its GenAI Platform and Donovan defense product). Hiring covers ML research, infrastructure engineering, applied AI for defense and enterprise customers, and forward-deployed roles that embed with customers; the interview process is known for being fast-moving and heavy on practical coding and applied-ML problem solving. Scale is a strong destination for engineers who want exposure to the full data-side of the AI stack rather than only the model side.
