Two Six Technologies is seeking a Principal Vulnerability Researcher. This role is technical at its core – along with in-depth reverse engineering and exploit development you will transition those findings into capabilities.

You will be a key player in a small fast paced team, owning your own projects and developing client relationships. Working with our lead Reverse Engineer, you will have access to top experts in the field with experience across a range of domains. You will have numerous opportunities to define your work.

Job Responsibilities & Duties
Given the technical nature of this role, experience in computer science, computer engineering, or a similar field is required. Significant proven experience in reverse engineering (RE) or vulnerability research (VR) can show your fit even if your background is outside of one of these fields.

You should be comfortable taking on complex technical problems for which there is often no known answer. You should be comfortable with ambiguity and forging your own path; our small team setting will provide you opportunity for outsized impact. While you will receive extensive training, mentorship, and coaching, you must be comfortable executing against goals independently since there’s no playbook for breaking unique complex systems.

Qualifications & Skills- Required:
Bachelor’s (or higher) degree in computer science, engineering, or a related field (solid knowledge in RE or VR may substitute for a specific degree)
Minimum 7 years of experience firmware development using low-level programming languages (C and at least one assembly language), scripting languages (e.g., Python), and the *nix command line
Strong familiarity with cybersecurity principles and a strong interest in learning more
Minimum 5 years of experience with common disassemblers/decompilers and reverse engineering tools (IDA, Ghidra, Binary Ninja)
Experience with software reverse engineering concepts: static analysis, dynamic analysis, fuzzing techniques
Active US Security clearance of Secret level and ability to obtain and maintain TS.

Nice to have, but not expected:
Familiarity with Binary Ninja API or Ghidra scripting
Familiarity building or securing embedded devices and other digital systems
Familiarity with embedded binary reverse engineering (ARM, RTOS, etc.)
Familiarity with basic cryptography design and implementation concepts
Experience in a client-facing technical role
