Develop and maintain fingerprints and security plugins derived from publicly available information
Fetch and aggregate service banners across multiple networking/communication protocols and ports (e.g., HTTP/S, SSH, FTP, SNMP, MQTT, Telnet, SMB) using protected, read-only methods.
Design robust regular expressions and XML-based rules for fingerprinting and detection.
Implement concise, well-documented Python plugins to parse banner data and normalize identifying attributes.
Writing unit and integration tests for fingerprints/plugins into CI/CD pipelines and run automated tests (Jenkins).
Maintain version control and code review discipline (Git).
Collaborate with product/security teams via Jira and Git to triage findings, track issues, and roll out updates.
Use AWS at a basic operational level to deploy and run passive data collection and processing infrastructure.
Perform data analysis using our custom analytics tool; basic SQL knowledge required to query and validate results.
Evaluate and responsibly leverage open-source reconnaissance tools for passive discovery and validation; extend tooling where necessary while adhering to non-intrusive usage policies.




Produce transparent technical documentation, including methodology, assumptions, validation steps, and change logs.
