Techniker Krankenkasse Tech Stack

Germany's largest health insurance fund digitizing legacy systems at scale

Insurance Hamburg, Hamburg 10,001+ employees Nonprofit

Techniker Krankenkasse operates a sprawling Java monolith (described as their largest application) supported by REST APIs and a legacy platform now being modernized. The tech stack reveals a mature but aging architecture: SAP HANA, Red Hat Enterprise Linux, and manual API governance via Kong and Apigee. Terraform adoption signals infrastructure-as-code migration to Azure and OpenShift. The hiring mix (56 healthcare roles vs. 17 engineering) reflects their operational reality: a service organization first, tech second, scaling member-facing processes faster than engineering capacity to support them.
