Responsibilities
Reverse engineer embedded firmware, device drivers, and proprietary telecom systems to identify undocumented functionality and potential security issues
Analyze telecom protocol stacks—including signaling, control plane, and data plane components—to support vulnerability discovery
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
