AI Engineer

What is a AI Engineer?

An AI engineer builds real applications using models that already exist, rather than training new ones from scratch. The work looks a lot like software engineering with an unusual component in the middle: the model is powerful but unpredictable, so much of the job is designing around that — giving it the right context, checking what comes back, and measuring whether the whole thing actually works. It is one of the newest roles in tech and the expectations are still settling.

• AI assistants and chat interfaces
• Retrieval systems over a company's own documents
• Agents that carry out multi-step tasks
• Model-powered features inside existing products
• Evaluation pipelines that measure output quality

• You like building things at the edge of what's settled
• You are comfortable when there is no single right answer
• You enjoy experimenting and measuring results
• You can be sceptical about impressive-looking output
• You want software skills plus something newer

Worth knowing before you commit. Every path has these.

• The model is confidently wrong sometimes, and you must design for it
• Testing is hard when the same input can give different output
• Costs and latency add up quickly at real usage
• Best practices change faster than they can be written down
• It is easy to build a demo and hard to build something reliable
