IT Services and IT Consulting Blue Bell, Pennsylvania 10,001+ employees Public Company

Unisys operates a sprawling legacy-to-cloud transition playbook: the tech stack mixes .NET, COBOL, FORTRAN, and Oracle alongside aggressive Azure and Kubernetes adoption, while simultaneously replacing VMware, Windows 10, and older ITSM tooling. Engineering dominance in their hiring mix (288 roles) paired with acute pain points around legacy system migrations, compliance, and downtime suggests a company in managed transformation mode, helping clients through infrastructure modernization while modernizing itself.
