Overview of Opportunity 

Join the Exploitation Sector of Two Six Technologies—a team of dedicated hackers in Arlington, Virginia—where you’ll immerse yourself in cutting-edge Vulnerability Research on a wide range of unique embedded systems. Working side by side with top-tier CNO developers and hardware engineers, you’ll discover vulnerabilities and create proof of concepts on embedded systems. Our fast-growing roster of government customers relies on us to deliver advanced security solutions, and we’re looking for a Principal Software Reverse Engineer to help us continue pushing boundaries. If you’re passionate about building tools that make a tangible impact on national security, we want you on our team.

Responsibilities Include

• Perform vulnerability research on complex embedded systems
• Take on complex technical problems for which there is often no known answer
• Develop tools and techniques to assist/automate tasks that traditionally require significant manual reverse engineering effort 
• Follow-on development to productize results/PoCs or handoff to developers for productization
• Provide technical leadership and direction on novel research projects, and interface directly with clients/key stakeholders to present findings and determine program direction
• Mentor and develop junior team members through knowledge-sharing, code reviews, and hands-on guidance, fostering their growth

Minimum Qualifications

• Bachelor’s (or higher) degree in Computer Science, Computer/Electrical Engineering, or a related field (or equivalent practical experience).
• Minimum of 9 years of experience with programming/scripting languages in C/C++, Python, and Linux command-line environments.
• Experience with reverse engineering and vulnerability research, using tools such as IDA Pro, Binary Ninja, or Ghidra.
• Expertise in one or more of the following:
• Firmware analysis (ARM, MIPS, PowerPC, RTOS).
• Firmware rehosting using emulation tools such as QEMU
• Fuzzing and exploit development.
• Binary obfuscation and anti-analysis techniques.
• Wireless protocols and radio signal analysis.
• File system forensics and fault injection frameworks.
• Experience leading a team of engineers and researchers

Nice If You Have

• Experience in a client-facing technical role
• Experience reverse engineering binary payloads from multiple architectures (ARM, MIPS, TI, x86, x64)
• Experience reverse engineering data payloads at rest (custom file formats) and in flight (live data captures)
• Experience with invasive and non-invasive hardware analysis, including PCB/component identification and hardware manipulation
• Hands-on experience debugging embedded systems using JTAG, UART, oscilloscopes, and logic analyzers

Clearance Requirements:

• Active Top Secret clearance with eligibility/willingness to obtain a Top Secret/SCI clearance. Prefer active TS/SCI with Poly
