Senior Vulnerability Researcher (Top Secret/SCI)

What we're looking for:

We need a senior security researcher with 5+ years of hands-on vulnerability research and exploit development experience who can independently explore and exploit complex systems — from kernels to embedded platforms. You should be comfortable scoping ambiguous attack surfaces with minimal guidance and have a track record of producing high-impact findings that influence security decisions. An active US Top Secret clearance (upgradeable to TS/SCI SAP) is required.

What you'll do:

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

- Independently scope ambiguous or underexplored attack surfaces and drive research from initial hypothesis through validated findings

- Perform deep reverse engineering and in-memory analysis of compiled binaries across multiple architectures (x86/x64, ARM, PowerPC)

- Design and execute novel exploitation techniques and mitigation evaluations, identifying real-world weaknesses in modern defense mechanisms

- Analyze undocumented or partially documented system behavior and extend internal interfaces or tooling to support research goals

- Collaborate with other senior researchers to shape technical direction, review complex work, and raise the overall quality of research output

- Translate low-level technical findings into clear, actionable insights for internal stakeholders and customers

- Contribute to research culture through mentorship, knowledge sharing, and improvements to tools, methodologies, and workflows
