AI Infrastructure Skill Map

Which skills each layer of the stack is hiring for — extracted from full job descriptions (ATS boards), normalized into a skill graph. Hiring requirements are a leading indicator of which technologies are winning. Not investment advice.

Source: required/preferred skills extracted from full ATS job descriptions; demand = number of open roles.
