Bugcrowd is seeking a Cleared Vulnerability Research Engineer to design, develop, and validate novel vulnerability discovery and exploitation capabilities against complex software and systems. This is a highly technical, independent role focused on end-to-end exploit development for real-world targets, operating at the OS, binary, and micro-architectural levels. Key responsibilities include: - Design and develop novel vulnerability discovery and exploitation capabilities - Conduct expert reverse engineering of binaries (x86-64, ARM64, etc.) using tools like Binary Ninja, Ghidra, or IDA Pro - Identify and exploit real-world vulnerabilities including use-after-free, type confusion, integer truncation, and buffer overflow - Discover new, previously unknown vulnerabilities in complex systems - Employ both manual analysis and automated techniques (fuzzing) for vulnerability discovery - Code and debug complex functions in C, Python, and Assembly - Independently manage research objectives from scoping through validation and iteration - Travel to customer sites as required, including extended on-site periods in cleared facilities Required qualifications: - TS/SCI security clearance (inactive SCI acceptable if SCI-clearable) - Demonstrated expertise in binary reverse engineering and exploit development - Proven ability to discover novel vulnerabilities, not just exploit known ones - Proficiency in C, Python, and Assembly (x86-64, ARM) - Ability to independently translate under-defined mission objectives into concrete technical capabilities - Comfort operating with minimal supervision and incomplete problem definitions - Willingness to travel to customer locations This role offers significant technical autonomy and the opportunity to work on cutting-edge security research. The position is remote-based but requires periodic travel to customer sites, particularly in Alabama for work in cleared spaces.
