What to look for when hiring AI engineers?

Before naming providers, here are the key criteria you should use to compare-

Criterion Why it matters
Domain/stack expertise (NLP, computer vision, large language models, MLOps, data pipeline etc.) AI is broad. An engineer good at ML model experimentation might not be strong in production deployment or infrastructure.
Track record/portfolio Hunt for evidence: projects shipped, clients, case studies.
Quality of vetting/hiring process Strong technical screening, real-world problem solving, rather than theoretical-only tests.
Team vs individual/contractor vs full-time Do you want someone embedded long-term, or just to deliver a prototype?
Communication/collaboration Remote work especially demands good habits. Also, timezone/language alignment matters.
Cost & risk Include things like IP, NDA and trial periods. Hidden costs in poor quality or delays can be big.

💬 Thought for the Leading Mind!

AI is one of the most important things humanity is working on. It is more profound than, I dunno, electricity or fire.
