- Demonstrated ability to independently identify and characterize vulnerabilities, misconfigurations, or exploitation techniques
- Strong understanding of network protocols, service fingerprinting, and Internet-scale scanning concepts (or a fast ability to pick them up)
- Proficiency in scripting or coding (Python, Go, or similar) to build tooling, automate testing, or analyze large datasets
- Familiarity with red team frameworks and tradecraft (C2 frameworks, initial access techniques, living-off-the-land methods, evasion)
- Comfort working with large-scale Internet scan data or a strong interest in learning to do so
