Information Technology & Services Madrid, Madrid 201–500 employees Founded 2003 Privately Held

GRUPO NS is a Madrid-based systems integrator executing large-scale infrastructure and application migrations—moving legacy mainframe workloads (z/OS, SAS) to distributed and cloud platforms (AWS, Azure), while simultaneously implementing modern enterprise stacks (Salesforce CDP, SAP SuccessFactors). The hiring profile is heavily weighted toward mid-to-senior engineers (88 of 120 roles), with active pain points around SAP integration, legacy Java modernization, and deployment automation, indicating a business built on complex, phased transformation projects rather than product licensing.
