About the role

• Hands-on experience writing scanner detections, signatures, or parsing scripts (Python, regex, protocol fingerprints)
• Experience with honeypots, deception tech, or internet-wide scanning and other large security datasets
• Strong Python and SQL skills
• Excellent communication with both technical and non-technical audiences
• A track record of clear documentation or public security writing, plus the judgment to lead complex work independently
