At NLR, you'll find a mission-driven environment supported by state-of-the-art facilities, multidisciplinary research teams, and strong collaborations with industry, academia, and other national laboratories. We offer robust professional development opportunities, and a competitive benefits package designed to support your career and well-being.

Job Description

The National Renewable Energy Laboratory (NLR) is seeking a skilledCybersecurity Researcher Reverse Engineerto join our Cyber Threat Analysis Group, within the Cybersecurity Research Center. This role requires candidates to analyze, deconstruct, and evaluate the security of highly complex embedded devices and systems that are critical to the nation's energy infrastructure and national security.

You will conduct deep-dive vulnerability research on hardware and firmware found in Industrial Control Systems (ICS), smart grid components, electric vehicle supply equipment (EVSE), and distributed energy resources (DERs). Drawing on a comprehensive understanding of system internals, cryptography, and network protocols, you will reverse engineer proprietary systems to uncover zero-day vulnerabilities, develop reliable exploits in constrained environments, and design system-level mitigations to secure the energy grid against advanced persistent threats (APTs).

Responsibilities include:

• Design and deploy advanced discovery techniques against black-box embedded systems. Implement custom fuzzing harnesses for hardware-in-the-loop and emulated environments.

• Develop robust, weaponized proof-of-concept (PoC) exploits for constrained environments. Bypass embedded exploit mitigations. Write custom shellcode and achieve persistent execution within RTOS or bare-metal environments.

• Intercept, reverse engineer, and exploit communications across all layers. Analyze local hardware buses (CAN, I2C, SPI), industrial control protocols (Modbus, DNP3, IEC 61850 GOOSE/SV, CIP/EtherNet/IP), and modern Smart Grid/EV protocols (OCPP, IEEE 2030.5, MQTT).

• Perform static and dynamic analysis of compiled binaries, RTOS (e.g., VxWorks, QNX, FreeRTOS), and bare-metal systems. Reverse engineer boot sequences, evaluate kernel-level internals, and identify privilege escalation vectors from user-space tasks to the kernel or hypervisor.

• Defeat hardware security mechanisms and extract firmware using debug interfaces (JTAG, UART, SWD). Execute advanced hardware attacks, including side-channel analysis and fault injection (glitching), to extract cryptographic keys or bypass authentication.

• Translate highly technical vulnerability findings and exploitation mechanics into actionable intelligence. Brief technical peers, leadership, and federal stakeholders on systemic risks to critical infrastructure and propose hardware/software mitigations

Researcher IV:

• Solves uniquely significant problems:Defeats advanced hardware security mechanisms (Secure Boot, TrustZone) utilizing novel techniques like side-channel analysis and fault injection.

• Serves as a technical authority:Briefs federal stakeholders and influences directorate-level strategy regarding systemic risks to critical infrastructure.

• Translates national needs:Directly addresses national security priorities by developing advanced mitigations against Advanced Persistent Threats (APTs) targeting the energy grid.

• Drives lab-wide capability:Architects and maintains custom reverse engineering plugins and automation frameworks utilized by multiple teams across the laboratory.

• Mentors at the lab level:Serves as a recognized expert, mentoring staff across the organization in highly specialized areas like kernel-level privilege escalation and deep firmware analysis.

Researcher III:

• Solves complex problems:Develops robust proof-of-concept exploits and performs deep static/dynamic analysis on constrained embedded environments.

• Leads project-level decisions:Designs and deploys advanced vulnerability discovery techniques, including custom fuzzing harnesses and symbolic execution.

• Applies broad engineering concepts:Adapts established principles to bypass exploit mitigations (e.g., ASLR, DEP/NX) on ARM, MIPS, and PowerPC architectures.

• Coordinates project efforts:Guides the technical execution of intercepting and analyzing complex hardware buses (CAN, SPI) and industrial protocols (Modbus, DNP3).

• Represents the laboratory:Translates highly technical vulnerability findings into actionable intelligence for internal peers and project leadership.
