Your Tasks

Topics like Observability, Egress Monitoring and the operative protection from Data Exfiltration in a highly available and load-intensive modern infrastructure for more than 43 million users sounds exciting to you? You're not only using technology, you push it to its limits and beyond? Then we are looking for you!

You will design, develop, and operate new technologies and products for observability, intrusion detection, exfiltration prevention, DNS infrastructure and firewalls in close cooperation with experts and colleagues, substantially driving architectural decisions forward.
You will work "hands-on" on sustainable solutions from concept via go-live to shut-down, including automating processes and creating transparency about the status of systems.
You are the contact person for technical questions, interface between network conception and application operations, supporting colleagues in the use and optimization of network segmentation and firewalling.
You keep the systems running, identify anomalies and get to the bottom of them.
