IT Services and IT Consulting Frauenfeld, Thurgau 51–200 employees Founded 2003 Public Company

itesys AG is a Swiss SAP specialist firm built around infrastructure, basis administration, and integration work. Their tech stack is almost entirely SAP-centric (SAP PI/PO, Integration Suite, BTP, S/4HANA, SuccessFactors) plus virtualization (VMware, Kubernetes) and cloud (Azure, AWS, GCP) — a shape that reflects deep customer dependency on SAP landscape stability. Active hiring is heavily skewed toward senior and lead engineers (12 of 15 engineering roles), with concurrent focus on interface migration and S/4HANA projects, signaling they're scaling execution capacity for complex modernization engagements.
