Overview of Opportunity

Join the Trusted Electronics & Effects team at Two Six Technologies in Arlington, Virginia, where we push the boundaries of software and firmware reverse engineering to uncover vulnerabilities in wireless and embedded systems. As part of our elite team of security researchers, you’ll work alongside CNO developers and hardware engineers, conducting cutting-edge vulnerability research on complex, real-world targets.

Our government customers rely on us to deliver mission-critical security solutions, and we’re looking for a Senior Vulnerability Researcher who thrives on reverse engineering embedded systems, discovering security weaknesses, and developing innovative proof-of-concept exploits. If you’re passionate about wireless security, embedded firmware analysis, and making an impact on national security, we want you on our team.

What You’ll Do:

- Act as a key technical contributor by analyzing binaries, firmware, and wireless protocols, reverse engineering complex targets, and writing maintainable proof-of-concept exploits following DevOps best practices.

- Utilize and develop custom tools to analyze and manipulate software/firmware binaries.

- Collaborate closely with CNO developers, vulnerability researchers, and hardware engineers in a fast-paced, small-team environment.

- Solve complex technical challenges with no predefined solutions.

What You’ll Need (Basic Qualifications):

- Bachelor’s (or higher) degree in Computer Science, Computer/Electrical Engineering, or a related field (or equivalent practical experience).

- Experience developing, debugging, and scripting in C/C++ and Python within Linux command-line environments, with a strong emphasis on low-level programming, memory management, and system interaction for reverse engineering and vulnerability research.

- 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.

- Knowledge of common network protocols TCP/IP, UDP, or HTTP

- Ability to work in the Arlington, Virginia office daily.
