- Ownership and execution of a continuous program running XBOW against public bug bounty programs, e.g. companies using HackerOne.
- Ownership and execution of a program running XBOW in collaboration with open-source projects (program to be launched in Q2).

Requirements:
- Professional, hands-on, pentest or cybersecurity research skills.

- Experience working either side of a bug-bounty program.
- Professional writing in other languages.
Benefits:
