What Is AI Engineering, and How Is It Different From Traditional ML?

Job titles blur. AI engineering often emphasises integrating and evaluating foundation models, while traditional ML engineering often emphasises training and tuning models on your data—yet evaluation and reliable deployment matter in both.

Key points

• Read the posting for tasks: training loops versus integration and evaluation workflows
• Expect shared responsibilities: data quality, metrics, failure modes and deployment checks
• Do not assume a short GenAI workshop equals classical ML depth—or the reverse

Illustrative example

Applied contrast on one product question: “Answer policy questions from our docs.”

Traditional ML-leaning path: label historical tickets, train a classifier or ranker, evaluate precision/recall, deploy with monitoring for drift.
AI engineering-leaning path: chunk documents, retrieve relevant passages, prompt a foundation model, evaluate groundedness on a test set, add human escalation for low-confidence answers.

Overlap: both need evaluation sets, failure notes and a deployment/rollback story.
Difference: one invests more in training data and model fitting; the other invests more in retrieval quality, prompt/tool boundaries and output checks.
Postings may use either title for either mix—inspect the work, not only the label.

How WorkReady practises this

WorkReady 90’s AI & ML and Agentic AI practice covers classical evaluation ideas and GenAI/RAG-style workflows at professional-practice depth so you can recognise what a posting actually asks for—without claiming specialist mastery of every ML subfield.
