MLOps Engineer
Also known as: ML Platform Engineer
Builds and maintains the infrastructure with which machine learning models are trained, deployed and monitored, and automates retraining when models grow stale.
The mlops engineer ensures data scientists' models go into production reliably and repeatably, with automated pipelines for training, validation and rollout. Unlike the machine learning engineer who focuses on a specific model, they build the platform on which multiple models run at once. Selection often focuses on knowledge of ml models, while recognising that a pipeline silently uses stale data instead of training fresh is the biggest source of unnoticed quality decay in practice.
