• A technically driven environment that encourages innovation and deep technical exploration.

• Opportunities to publish research present findings or contribute to classified mission success.

• A team culture that values technical mastery curiosity and mentorship.

• Support for continued learning certifications and reverse engineering challenges.

Responsibilities:

• Reverse engineer embedded firmware device drivers and proprietary telecom systems to identify undocumented functionality and potential security issues.

• Perform firmware extraction binary diffing static and dynamic analysis and hardware-assisted debugging.

• Collaborate with hardware engineers to access debug interfaces (e.g. JTAG SWD) extract flash images and inspect hardware state.

• Develop custom tools and scripts (e.g. in Python3) to automate analysis workflows such as firmware unpacking protocol decoding and memory analysis.

• Investigate edge-case behaviors error-handling routines and low-level system initialization logic to reveal attack surfaces.

• Document findings clearly and translate technical complexity into actionable reports for security and engineering teams.

Qualifications:

Required:

• Must be a US Citizen and the ability to obtain a security clearance.

• 5 years of professional experience in embedded software development with reverse engineering skills.

• Proficiency in C C and assembly programming for embedded architectures such as ARM MIPS x86 or RISC-V.

• Experience with RTOS environments including VxWorks and embedded Linux device driver development.

• Understanding of embedded software IPC mechanisms such as message queues shared memory and semaphores.

• Familiarity with embedded hardware interfaces including SPI I2C PCIe UART and memory-mapped I/O.

• Proficient in Python3 for scripting and automation.

• Hands-on experience with disassembly and decompilation tools (e.g. IDA Pro Ghidra Binary Ninja) and debugging tools (GDB JTAG).

• Knowledge of embedded security concepts including secure boot firmware encryption and hardware authentication.

Desired:

• An active security clearance is highly desired.

• Experience in cybersecurity research vulnerability discovery or exploit development in embedded or telecom environments.

• Familiarity with PowerPC assembly including QUICC-based systems.

• Experience with ARM assembly and debugging of SoC-based embedded platforms.

• Understanding of Linux kernel internals and/or VxWorks internals.

• Hands-on experience with FPGA-based systems including those with embedded ARM or PowerPC cores.

• Background in embedded hardware design and debug including the use of oscilloscopes logic analyzers and firmware extraction techniques.

• Ability to build tools and infrastructure to support analysis workflows in a team setting.
