Business-function AI Builders

Function-native AI Builders

Every business function is hiring an AI Builder of its own — Marketing, Finance, HR, Legal, Sales, Operations, Customer Experience. The role is being invented in real time. The market has 228 distinct titles for this layer and zero canonical names.

Engineering AI Builders

Engineering AI Builders

The loud layer. The market has already named these roles — ML Engineer, AI Engineer, Applied AI, Forward Deployed Engineer, Agentic Developer, Prompt Engineer, plus the newest pair: AI Accelerator (internal FDE) and AI Solution Architect. These are the platform team that the function-native AI Builders lean on.

AI Operators & Cross-Functional Roles

Cross-functional & Leadership

Roles that sit above or across function lines. Executives steering AI (CAIO, Head of AI, VP AI, Director AI). Governance owning its impact on people and society (Responsible AI Officer). Ambassadors translating capability to audiences (AI Evangelist). Non-engineer builders shipping software via AI (Vibecoder).

Off the org chart

The AI trainer gig layer

Beneath every named AI role sits a contingent-labor layer: domain experts hired per-task to train, evaluate, and red-team models. Not employees, not headcount — a labor market parallel to the org chart. Mercor reports ~30,000 contractors at an average billed rate near $95/hr; Scale AI's Outlier runs a similar platform. Where the judgment, taste, and domain expertise that tunes today's models actually comes from.
