Since its creation, Jaeger-LeCoultre has made precision an art in its own right, finding the perfect balance between cutting-edge know-how and artistic sense, sophistication and aesthetic finesse. Faithful to the spirit of invention initiated in 1833 by its founder Antoine LeCoultre, the craftsmen of the Manufacture create collections at the cutting edge of Haute Horlogerie: Reverso, Master, Jaeger-LeCoultre Polaris, Rendez Vous and Atmos - this rich heritage built by the Grande Maison over the centuries is a constant source of inspiration that never ceases to push the limits through unprecedented timepieces.


For our Manufacture located in Le Sentier (Vallée de Joux - Canton of Vaud), within the Operations Department and directly attached to the Information System & Organization department, you will be in charge of the study and development of processes aimed at integrating new data into a Data Warehouse. These will then make it possible to set up new performance indicators (KPIs) in connection with supplier quality. To do this, you will be in continuous dialogue with a business expert who will be able to both describe their own needs and assist you in developing these new indicators.

  • User needs study
  • Study of the existing Data Warehouse, the model used and its operation
