Job Overview: As a Security Engineer - Fuzzing Specialist , you will own and evolve our coverage-guided fuzzing program. Your mission is to uncover hard-to-reach security flaws before attackers do, drive fixes to closure, and help product teams to embrace dynamic testing like fuzzing. You'll scout for new attack surfaces, craft high-performance fuzzing harnesses, and design … custom sanitisers that push the state of the art. Success means measurable coverage gains, actionable crash reports, and products that ship with provable resilience. Responsibilities: Map & prioritise fuzzing surfaces across services, libraries, APIs, and protocols; maintain a living risk-based roadmap. Design, build, and extend fuzzing harnesses (libFuzzer, AFL , Honggfuzz, etc.) that improve code-path exploration and minimise false positives. … techniques. Automate crash triage & root-cause analysis ; distinguish exploitable vulnerabilities from benign faults and drive CVE-level findings to remediation. Develop custom sanitisers to expose classes of bugs traditional fuzzing misses. Validate fixes & guard against regressions through differential fuzzing and regression corpora. Assess external disclosures (bug bounties, supply-chain advisories) to determine fuzzing detectability and refine harnesses when gaps are More ❯
