  • Contribute to and help manage the bug bounty programs by validating and triaging reported vulnerabilities\n
  • Create and maintain security guidelines, best practices, and documentation tailored for ecosystem developers\nIn-Office Culture:\nThis is a remote position but we will prioritize applicants based in the Bay Area.

We believe in building together and sharing in the long-term success of the network. Compensation packages are designed to be competitive and aligned with the growth of both the team and the ecosystem.
