About the Opportunity

Our client is seeking an experienced Senior Vulnerability Researcher to join a highly technical team focused on advanced vulnerability discovery, reverse engineering, and exploit development. This is a hands-on research role for professionals who thrive on solving complex technical challenges and uncovering previously unknown vulnerabilities across a wide range of platforms.

What You'll Do

Lead advanced vulnerability research across operating systems, kernels, firmware, hypervisors, embedded platforms, and complex application stacks.

Independently identify and evaluate new attack surfaces, driving research from initial hypothesis through validated findings.

Perform deep reverse engineering and in-memory analysis of compiled binaries across x86, x64, ARM, and PowerPC architectures.

Develop and validate novel exploitation techniques while evaluating modern security mitigations, including ASLR, DEP/NX, and CFI.

Analyze undocumented system behavior and enhance internal research tools and automation.

Collaborate with senior researchers to drive technical innovation and improve overall research quality.

Communicate technical findings clearly to both technical and non-technical stakeholders.

Mentor team members and contribute to research methodologies, tooling, and knowledge sharing.

What We're Looking ForRequired Experience

6+ years of hands-on vulnerability research or exploit development experience.

Demonstrated success independently leading complex research projects with minimal direction.

Strong background in reverse engineering and exploit development rather than defensive security or security operations.

Experience supporting cyber operations, offensive security, or government research programs is highly valued.

Contributions to the security community, including CVEs, conference presentations, research publications, malware analysis, deobfuscation work, or CTF achievements, are a plus.

Technical Skills

Expert-level reverse engineering of operating systems, kernels, firmware, and compiled binaries.

Strong knowledge of assembly language across x86/x64, ARM, and PowerPC architectures.

Experience developing proof-of-concept exploits, vulnerability research, and mitigation bypass techniques.

Strong programming skills in C/C++ and Python.

Experience researching embedded systems, hypervisors, mobile platforms, RTOS, or networking protocols.

Proficiency with industry-standard research tools such as IDA Pro, Ghidra, fuzzing frameworks, symbolic execution tools, and related technologies.

Clearance & Education

Active U.S. Top Secret clearance with the ability to obtain TS/SCI with Special Access Program eligibility.

Bachelor's degree in Computer Science, Computer Engineering, or a related technical discipline preferred.
