What exactly does a Data Engineer do?
Le Data Engineer bâtit l'infrastructure qui collecte, transforme et sert la donnée à toute l'entreprise. Sans lui, les analystes et data scientists travaillent sur des données fausses, en retard ou indisponibles.
What you really need to understand: Le Data Engineer est jugé sur la fiabilité, pas sur la nouveauté : un pipeline qui tourne sans surveillance pendant six mois vaut mieux qu'une stack à la mode qui casse chaque nuit. La compétence rare, c'est de raisonner volumétrie, idempotence et coût cloud avant d'écrire une ligne.
