Noticing a pattern across this month's thread: companies want "AI engineers" but job descriptions break into two distinct archetypes: (1) people who can eval and fine-tune models, (2) people who can ship reliable agent pipelines in prod. Very few candidates can do both. At our fintech startup we ended up hiring two people for what we thought was one role. The infra/reliability side is consistently underestimated until the first prod incident.
