Enterprise Architect

Project overview

In a context of strong growth and structuring of its information system, a company in the technology sector wishes to build its enterprise IS from a limited existing application landscape, mainly composed of HubSpot (CRM) and Lucca (HRIS).

Reporting to the CTO and in close collaboration with the project manager, the Enterprise Architect is responsible for defining and designing the target functional and application architecture.

They will be involved in all areas of business management (finance, purchasing, supply chain, project management, product catalogs), with the objective of implementing a modular, scalable, and interconnected information system, without relying on a centralized ERP.

They will ensure the overall consistency of the architecture, control of data flows, and the definition of a pragmatic transformation roadmap over 12 months.
