Senior Vulnerability Researcher (Cyber267)

Position Title: Senior Security Researcher
Location: St. Petersburg, FL | Melbourne, FL | San Antonio, TX
Clearance Requirement: Top Secret/SCI
Employment type: Full Time

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

• Independently scoping ambiguous or underexplored attack surfaces and driving research from initial hypothesis through validated findings.

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

• Designing and executing novel exploitation techniques and mitigation evaluations, including identifying real-world weaknesses in modern defense mechanisms.

• Analyzing undocumented or partially documented system behavior and extending internal interfaces or tooling to support research goals.

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

• Translating low-level technical findings into clear, actionable insights for internal stakeholders and, when appropriate, customers.

• Contributing to research culture through mentorship, knowledge sharing, and improvements to tools, methodologies, and workflows.

• Conducted high-impact vulnerability research on real-world systems with minimal guidance, producing findings that influenced security decisions or mitigations.

• Demonstrated deep understanding of operating system internals (Windows, Linux, macOS), kernel subsystems, and low-level execution models.

• Reverse engineered complex binaries, firmware, or kernel components and reasoned about their behavior in memory.

• Developed proof-of-concept exploits or mitigation bypasses that go beyond simple crashes and demonstrate meaningful impact.

• Shown strong intuition for exploit mitigations such as ASLR, DEP/NX, stack canaries, CFI, and where their assumptions break down.

• Written research tooling, scripts, or frameworks (e.g., Python, C/C++) to support analysis, exploitation, or automation.

• Collaborated closely with other researchers, provided technical feedback, and influenced how work is approached or evaluated.

• Communicated complex technical concepts clearly in writing and discussion, including with other experts.

• Experience with hypervisors, virtualization stacks, firmware boot chains, or trusted execution environments.

• Background in embedded systems, RTOS environments, or mobile platforms (iOS/Android).

• Familiarity with networking or wireless stacks (Wi-Fi, Bluetooth, cellular) and their security models.

• Contributions to the vulnerability research community (publications, talks, open source).

• Experience with symbolic execution, constraint solving, fuzzing frameworks, or advanced program analysis techniques.

• Malware analysis experience, including deobfuscation, behavioral analysis, or adversarial tooling.

• Interest in shaping long-term research direction, mentoring other researchers, or acting as a technical authority without moving into management.
