Our Auth API & API Management team develops and operates central platform services that support EVENTIM's products across international markets.
A key part of our work is our central Identity & Access Management platform built on Keycloak. It enables secure authentication and Single Sign-On across different products and markets, operating internationally and handling high traffic volumes.
Closely connected to our identity platform are our API Gateway and API Management solutions, which ensure that APIs are exposed securely and reliably. Both areas are tightly integrated, particularly when it comes to authentication, authorization, and API security.
As a Senior Software Developer, you will work alongside your team to continuously develop and enhance these platforms, shaping essential solutions around Identity & Access Management, Authentication, and Security.
You can work from one of our offices in Hamburg, Bremen, or Berlin. We look forward to receiving your application!
