• Design and develop custom tools and software targeting embedded and telecommunications systems
• Serve as a cyber capability developer on a small, highly motivated team
• Develop proofs-of-concept from discovered vulnerabilities and transition them into robust, maintainable codebases following DevOps best practices
• Analyze firmware, software protections, operating system internals, and wireless protocols to uncover exploitable security flaws
• Conduct reverse engineering and vulnerability research against complex Linux-based and embedded systems
• Utilize and extend custom tools to analyze and manipulate software/firmware binaries
• Develop capabilities that leverage novel telecommunications access mechanisms
• Collaborate closely with developers, vulnerability researchers, and hardware engineers in a fast-paced environment
• Solve complex, ambiguous technical challenges with limited prior experience
• Engage in technical discussions with transition partners and mission stakeholders

What You Will Need (Minimum Qualifications):

• Bachelor’s degree in Computer Science, Computer/Electrical Engineering, or related scientific discipline
• Minimum 5 years of experience designing and/or prototyping applications using agile software development processes
• Minimum 2 years of experience with one or more of the following: Python, C, C++

• At least 2 years of experience with network socket programming and expert packet-level understanding of IP, TCP, and related application-level protocols
• At least 2 years of experience with reverse engineering x86/ARM binaries or embedded systems
• Experience tracing code execution in debuggers (WinDbg, GDB, or equivalent)
• Expertise in one or more of the following areas:

• Firmware analysis (ARM, RTOS, or similar)
• Fuzzing and exploit development
• Wireless protocols through Wireshark
• File system forensics and fault injection frameworks
• Scripting with Binary Ninja or Ghidra
• Binary Ninja API or Ghidra

• Active U.S. Top Secret security clearance with ability to obtain and maintain SCI access

Nice to Have (Preferred Qualifications):

• Familiarity with identifying and analyzing vulnerabilities in complex applications

Knowledge of memory protection mechanisms (ASLR, DEP, etc.)

• Experience with CI/CD pipelines and virtualized test ranges
• Experience with firmware or driver development across Linux, Windows, or embedded systems
• Strong understanding of memory management (heap, stack, virtual memory, MMU, physical vs. virtual addressing)
• Experience working with telecommunications systems, including protocol analysis, access mechanisms, or infrastructure components (5G experience a plus)
• Graduate degree in Computer Science, Computer/Electrical Engineering, or related field

Clearance Requirements:

• Active U.S. Security clearance of Top Secret level with the ability to obtain/maintain SCI
