Leihia Tech Stack

Next-generation ATS platform for French mid-market recruitment

Software Development Paris, Île-de-France 11–50 employees Founded 2019 Privately Held

Leihia is a SaaS-based applicant tracking system serving French HR and recruitment teams. The tech stack reveals a company mid-migration: legacy PHP sits alongside modern .NET Core microservices on Kubernetes, with Apache Airflow and n8n handling data pipelines and workflow automation. A hiring surge across engineering (133 roles posted in 30 days) signals aggressive product development, while finance hiring (54 roles) suggests scaling of back-office operations—a pattern typical of SaaS platforms moving beyond early product-market fit.
