Your Tasks

Are you passionate about cybersecurity and blue team topics like threat hunting, anomaly detection, and incident response? Do you thrive in an agile environment and want to contribute to a leading digital company? Join us as a Security Operations Engineer and help secure our products: WEB.DE, GMX, and mail.com! In this role, you’ll be at the heart of our operational security:

• Innovate and Enhance: Design and continuously improve processes and tools in key areas such as SIEM, cyber threat intelligence, threat hunting, vulnerability management, and digital forensics – helping us maintain a real-time understanding of our threat landscape.
• Lead Incident Response: Triage security alerts and take the lead as Incident Manager / Commander during confirmed incidents, coordinating cross-functional teams under pressure.
• Automate Workflows: Automate detection and response workflows, leveraging established platforms like SIEM or EDR/XDR, as well as your own custom scripts and playbooks.
