What We’re Looking for (Minimum Qualifications)

- Strong understanding of adversary behaviors, attack chains, and MITRE ATT&CK
- Hands-on experience with SIEM, EDR/XDR, log analysis, and scripting (Python/PowerShell)
- Ability to translate research into actionable detections and measurable metrics
- Knowledge of red team emulation frameworks and detection bypass techniques
What Will Make You Stand Out (Preferred Qualifications)
