lintégrateur

Lintégrateur, usually written l’intégrateur, is the French term for a system integrator: a professional who designs, implements and maintains integrated IT solutions by combining software, hardware, networks and services from multiple vendors to meet business objectives.

Key responsibilities include gathering requirements, designing reference architectures, selecting components, managing projects, orchestrating the deployment, configuring interfaces and middleware, conducting data migration and testing, and providing training and post-implementation support. The integrator coordinates vendors, subcontractors and stakeholders, ensures interoperability and performance, and addresses security, privacy and regulatory compliance throughout the project lifecycle.

Typical domains are corporate IT infrastructure, ERP/CRM integrations, cloud-to-on-premises hybrids, industrial automation, IoT and telecommunications. Technologies and patterns commonly involved include APIs and data contracts, middleware and integration platforms (such as ESB or iPaaS), data mapping and ETL processes, messaging queues, and monitoring tools. The role often requires knowledge of databases, networking, security practices, and vendor-specific stacks, as well as project management and change management.

Qualifications and career path vary by country but commonly include an engineering, computer science or information systems background, hands-on experience with integration projects, and certifications related to platforms or middleware. Skills emphasized are systems thinking, problem solving, stakeholder communication, vendor management and risk assessment. In French-speaking contexts the term aligns with the English “system integrator,” a professional commonly employed by consultancy firms, system houses, or large enterprises to deliver end-to-end integrated solutions.
