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. Youll 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. * 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. * Continuously improve coverage by growing seed corpus, deploying targeted mutation .
