- 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
