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.

As of October 2026, Scale AI has 55 open AI and agentic roles listed on AgenticCareers, spanning AI Agent Engineer, AI Researcher, AI Infrastructure. It also lists 5 non-AI roles, which are not counted here.
