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
Continuously improve coverage by growing seed corpus, deploying targeted mutation strategies, and integrating new instrumentation 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 found
Document, report, and share insights — from coverage metrics to post-mortems to create data-driven security
Qualification
Required
1+ years in application or product security with a deep focus on coverage-guided fuzzing
Hands-on expertise with at least one modern fuzzing framework (e.g., libFuzzer, AFL++, Honggfuzz)
Proficient in C/C++ plus strong scripting ability in Python for automation
Solid understanding of memory-safety vulnerabilities, undefined behaviour, sanitisers, and compiler instrumentation
Demonstrated ability to triage crashes using debuggers, profilers, and reverse-engineering tools (gdb/lldb, IDA/Ghidra)
Excellent written communication for documenting findings and influencing engineering teams
Preferred
Contributions to open-source fuzzing tools, sanitisers, or security research publications
Knowledge of distributed fuzzing at scale (GCP/AWS, Kubernetes, or bare-metal clusters)
Familiarity with kernel, embedded, or firmware fuzzing (e.g., Syzkaller, QEMU-based harnesses)
Background in reverse engineering, static analysis or symbolic execution
Experience integrating fuzzing into CI/CD pipelines and tracking coverage metrics
