IBM Tech Stack

Enterprise cloud, AI, and infrastructure platform for large-scale digital transformation

IT Services and IT Consulting Armonk, New York, NY 10,001+ employees Public Company

IBM operates a multi-layered infrastructure and software business built on Red Hat, OpenShift, Kubernetes, and Watson, now absorbing observability tools (Elasticsearch, Splunk) and open LLMs (Mistral, Llama 3) while migrating customers away from legacy SAP ECC. The hiring mix—heavily weighted toward engineering (667 roles) and data (244)—paired with active projects around GenAI code modernization (COBOL-to-Java refactoring) and S/4 HANA migration, reflects a company in the middle of reshaping its own infrastructure while helping enterprises do the same.
