Our teams specialize in reverse engineering, vulnerability research, and security engineering, supporting mission-critical efforts across national security, defense, and critical infrastructure sectors. Our work is rooted in real-world operational experience identifying advanced threats, uncovering critical vulnerabilities, and developing meaningful solutions to complex problems. Grimm engineers operate across embedded systems, vehicles, IoT, and enterprise technologies, with a focus on understanding systems deeply and demonstrating real-world impact. We are a highly technical and hands-on organization. Our engineers and researchers specialize in breaking systems, discovering vulnerabilities, and improving resilience—working directly with real hardware and software to understand how systems function and how they fail. About the Role Grimm is seeking multiple Vehicle Embedded Security Researchers and Reverse Engineers to work directly with automotive systems, firmware, and hardware platforms. This role is centered on vehicle-focused vulnerability research and reverse engineering, including ECUs, infotainment systems, and in-vehicle networks. You’ll be working hands-on with real vehicles and hardware by analyzing, modifying, and testing systems to uncover vulnerabilities and develop deep technical understanding. We’re looking for individuals who are curious, driven, and enjoy working at the lowest levels of systems—those who aren’t satisfied until they fully understand how something works. What You’ll Do: • Reverse engineer automotive firmware and embedded systems
• Analyze and assess vehicle electronic systems (ECUs, infotainment, telematics, control systems)
• Perform vulnerability research on embedded and hardware platforms
• Interface with and analyze vehicle networks (CAN, LIN, Automotive Ethernet)
• Develop tooling for protocol analysis, fuzzing, and exploitation
• Conduct hardware debugging and data extraction using interfaces such as JTAG, SWD, UART, SPI, and I2C
• Perform binary analysis using tools such as Ghidra, IDA Pro, or Binary Ninja
• Research and develop novel attack techniques against vehicle systems
• Collaborate with cross-functional teams spanning software, hardware, and cybersecurity Required Qualifications: • Active Secret clearance • US Citizenship
• Experience in one or more of the following areas: o Automotive systems (ECUs, CAN bus, infotainment, diagnostics) o Embedded systems development (C/C++, firmware, RTOS) o Reverse engineering or vulnerability research
• Strong understanding of low-level systems (memory, system architecture, firmware)
• Ability to clearly communicate technical findings in both written and verbal formats Preferred / Nice to Have: • Automotive cybersecurity experience: o CAN bus analysis, UDS diagnostics, Automotive Ethernet
• Hardware security experience: o Side-channel analysis, fault injection/glitching o Chip-off / flash extraction o Debug interfaces (JTAG, SWD, UART, SPI, I2C)
• Reverse engineering & exploitation: o Firmware analysis, binary reversing, exploit development o Fuzzing and code execution techniques
• Experience with tools such as Ghidra, IDA Pro, or Binary Ninja
• Background in: o Offensive cyber operations (CNO) o Military, intelligence, or law enforcement environments
• Experience experimenting with AI/LLMs for security research or tooling Benefits Grimm offers a comprehensive benefits package that includes medical, dental, and vision coverage, life and disability insurance, retirement benefits, paid leave, and opportunities for tuition assistance and ongoing professional development. Why Grimm You’ll be working alongside highly specialized engineers and researchers tackling challenging problems in embedded security and reverse engineering. Our work directly supports national security missions and requires a high level of technical ownership, creativity, and precision.
