Job summary

Leidos is seeking a Cyber-Physical Systems Reverse Engineer to analyze real embedded and cyber-physical systems in lab environments, reversing firmware, emulating devices, and designing experiments to reveal unexpected behavior.

You will build test harnesses, develop production-quality C/C++ and Python tools, and work on hardware interfaces, NICs, and RTOS-based software to advance maritime cybersecurity capabilities.

Qualifications

• Experience developing embedded firmware in C/C++, RTOS concepts, interrupts, concurrency, memory-mapped I/O, device drivers, and hardware peripherals.
• Experience with 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 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; critically analyze, document, and communicate technical findings.
