- Forensics & Analysis: In-depth investigation of anomalies and attack patterns using SIEM systems (e.g. Splunk, QRadar) and EDR solutions (e.g. CrowdStrike, Microsoft Defender).
- Threat Mapping: Classification and documentation of attack vectors using the MITRE ATT&CK framework to identify tactics, techniques and procedures (TTPs).
- Network analysis: Detailed analysis of network traffic and protocols (e.g. using Wireshark) to detect malicious activity.
- Crisis communication: Preparation and communication of incidents to technical teams, stakeholders and management in an appropriate manner.
- Continuous improvement: Carrying out post-incident reviews (“lessons learned”) to sustainably optimize detection and response capabilities.

- Safe use of SIEM & EDR technologies: Demonstrable knowledge of SIEM systems (e.g. Splunk, QRadar) and modern EDR solutions (e.g. CrowdStrike, Microsoft Defender for Endpoint).
- Knowledge of modern threat models: Familiarity with the MITRE ATT&CK framework for targeted detection and analysis of attack patterns.
- Network forensics & log analysis: Practical expertise in deep analysis of network traffic and logs using tools such as Wireshark.
- Analytical problem solving & resilience: Excellent stress resistance and structured thinking skills in time-critical incidents.
- Clear communication: Ability to communicate complex technical issues precisely and to the recipient in German and English in the event of an incident.
That rounds off your profile (nice-to-have)
- Relevant security certifications such as GIAC (e.g. GCIH, GCFA, GNFA), CISSP or comparable evidence
- Experience with cloud security architectures and incident response in AWS, Azure, or GCP
- Knowledge of scripting for automation (e.g. using Python, PowerShell, or Bash)
- Basic malware analysis and reverse engineering experience
- Familiarity with Security Orchestration, Automation and Response (SOAR) platforms
What we offer
- Attractive compensation & security: A performance-based salary package, company pension plan and a crisis-proof job in a future-oriented IT security environment.
