Vos missions

En tant que Data Engineer, vous êtes en charge de :

  • Développer les pipelines d'ingestion et de transformation avec Fabric Data Factory et Dataflows Gen2
  • Migrer les données depuis Google BigQuery vers les Lakehouses et Warehouses Fabric
  • Construire les connecteurs et workflows pour extraire les données depuis SAP, Salesforce, Oracle et des partages de fichiers
  • Ré-implémenter la logique ETL existante (Talend) dans l'environnement Fabric, en collaboration avec l'ingénieur Talend dédié
  • Encadrer les ingénieurs juniors de l'équipe : revues de code, respect des standards, accompagnement technique
  • Diagnostiquer et optimiser les pipelines en production : performance, fiabilité, maîtrise des coûts
  • Produire la documentation technique complète : runbooks, tests unitaires, traçabilité dans Azure DevOps

Profil recherché

Formation et expérience

  • 7 ans et plus en ingénierie data avec une expérience concrète sur la stack data Azure
  • Expérience de migration de données depuis des systèmes sources hétérogènes : ERP, CRM, bases de données
  • Expérience en encadrement technique d'ingénieurs juniors sur un projet

Compétences techniques

  • Microsoft Fabric : maîtrise opérationnelle — Data Factory, Notebooks, Dataflows Gen2
  • Langages : Python (PySpark) et SQL — expertise en transformation de données à grande échelle

  • CI/CD : pratique concrète avec Azure DevOps et Git — commits documentés, déploiements tracés, tests unitaires
  • BigQuery : connaissance des mécanismes d'export et de la structure des données GCP

Posture et mode de travail

  • Autonomie technique sur un périmètre large : capable d'identifier un problème et de le résoudre sans escalade systématique
  • Rigueur documentaire : chaque pipeline livré est documenté, testé et lié à un work item dans Azure DevOps
  • Capacité à travailler en équipe pluridisciplinaire : architecte, QA, Talend, chef de projet
  • Français courant — anglais courant

Ce qui pourra faire la différence

  • Expérience directe sur Microsoft Fabric en environnement de production — pas uniquement en POC ou formation
  • Connaissance de Talend et capacité à lire et comprendre des pipelines ETL existants pour les re-implémenter
  • Expérience simultanée sur plusieurs sources complexes : SAP + Salesforce + Oracle sur un même projet
  • Disponibilité rapide souhaitée — à discuter selon profil

Modalités de travail

Mission hybride basée à Paris — rythme de présence sur site à définir avec le client.

Les modalités indiquées sont valables à la date de publication et peuvent évoluer selon les besoins du projet et du client. Cognizant s'engage à une transparence totale sur les attentes liées au poste.

Votre parcours ne correspond pas à 100 % ? Deux prérequis sont indispensables : une maîtrise réelle de Microsoft Fabric et une expérience terrain concrète sur la migration de données depuis des systèmes sources complexes. Ce qui fera ensuite la différence : la capacité à livrer du code propre, documenté et testé dans un contexte projet exigeant.
