Full Job Description
Security Engineer - Bug Bounty About the Role We are looking for a Security Engineer focused on Bug Bounty who treats researcher reports as security data, not support tickets. This is not a coordination role — you will be hands-on validating vulnerabilities, reproducing exploits, and working directly with engineering teams to drive fixes. You will own the full lifecycle of the program: scope design, triage, researcher relations, remediation tracking, and the upstream feedback that turns external findings into internal controls. The other half of this role is developer partnership. Findings that sit in a backlog do not improve security. You will reduce the friction that keeps confirmed vulnerabilities from being fixed — translating researcher reports into clear remediation guidance, removing ambiguity that slows engineers down, and identifying the process or tooling gaps that let the same vulnerability class appear repeatedly. A deep understanding of how vulnerabilities actually work — not just how to classify them — is fundamental to success here. What You'll Do Own day-to-day operations of the bug bounty program on the managed platform, including report triage, severity assessment, researcher communication, and payout decisions — maintaining SLA compliance across all inbound volume Reproduce and technically validate submitted vulnerabilities across web, API, mobile, and trading infrastructure attack surfaces — reason independently about exploitability in context, not just what the report claims Classify findings using CVSS, OWASP, and business impact criteria; distinguish genuine risk from theoretical severity; escalate critical issues into incident response workflows with enough context for engineering leadership to act immediately Act as a remediation partner, not just a reporter — work directly with developers to clarify findings, provide exploit context, reproduce issues where needed, and give fix guidance grounded in how the vulnerability actually works; track
