Hands-on Embedded CPS Reverse Engineer

Koitecc Solutions; Columbia, Northern (MD, KY); Hybrid; USD 108,000 - 195,000; Full time

Job summary

Leidos is seeking a Cyber-Physical Systems Reverse Engineer to research and develop novel capabilities for maritime cybersecurity. Work with embedded hardware, firmware, and software analysis in a lab environment to uncover unusual system behavior and undocumented features.

You will build test harnesses, emulate devices, and apply cyber reasoning tools across electronics, firmware, and software to deliver robust analyses and experiments.

Qualifications

• Experience developing embedded firmware in C/C++, including RTOS concepts, interrupts, concurrency, memory-mapped I/O, device drivers, and hardware peripherals.
• Experience with embedded hardware and interfaces such as SPI, I2C, UART, CAN, USB, Ethernet, or wireless interfaces, including debugging hardware/software interactions.
• Experience developing simulation, emulation, automated testing, or hardware/software test harnesses for embedded systems.
• Proficiency with Python or similar scripting languages for automation, testing, analysis, and development of engineering tools.
• Experience using embedded development and diagnostic equipment such as JTAG/SWD debuggers, logic/protocol analyzers, oscilloscopes, spectrum analyzers, function generators.

Responsibilities

• Develop, integrate, and debug embedded firmware for real-time and resource-constrained systems, including RTOS-based applications, device drivers, hardware interfaces, and low-level system software.
• Design and implement simulation, emulation, and automated test environments for embedded and cyber-physical systems, including tools for exploring system behavior, reproducing observed effects, and exercising hardware and firmware.
• Analyze and reverse engineer embedded devices, firmware, communications protocols, sensors, and other system components to understand both intended functionality and real-world behavior.
• Develop production-quality C/C++ and Python software to automate testing, instrumentation, experimentation, and analysis, including integration with laboratory hardware and software-based analysis tools.
• Conduct hands-on laboratory testing using embedded debugging tools and analog/digital instrumentation; document and communicate technical findings.
