SFEIR Tech Stack

Custom software development and cloud modernization for enterprise clients

IT Services and IT Consulting Neuilly-sur-Seine, Île-de-France 501–1,000 employees Founded 1985 Privately Held

SFEIR is a 500+ person development consultancy built around deep expertise in cloud, data, and AI platforms. The stack reveals infrastructure-as-code maturity (Terraform, Helm, Argo CD, Kubernetes) paired with emerging AI model adoption (GPT, Claude, Gemini, Mistral), while active projects show a shift toward event-driven architectures (Kafka integration) and managed data platforms (BigQuery, Databricks). Engineering-heavy hiring (44 of 68 open roles) with senior-weighted seniority mix signals focus on complex modernization engagements rather than staff-augmentation.
