NREL is seeking a mid-career Adversarial Cyber Researcher to join its Cybersecurity Research Center (CRC). The CRC conducts applied research at the intersection of cybersecurity, energy systems, and national resilience-developing the tools, methods, and scientific foundations necessary to secure and sustain the nation's evolving energy infrastructure. CRC research spans threat actor modeling and simulation, operational technology (OT) risk analysis, adversarial experimentation, hardware and software assurance, supply chain integrity, and cyber-physical resilience testing. Working across NREL's energy, grid, and systems integration missions, the CRC leverages unique laboratory assets-including the ARIES Cyber Range-to conduct large-scale, high-fidelity cybersecurity experiments and modeling. We are seeking a technically strong and research-focused professional to contribute to cyber adversarial science, threat emulation, and defense experimentation. The successful candidate will possess a deep understanding of offensive and defensive cybersecurity methodologies, hands-on experience designing and conducting controlled adversarial experiments, and a demonstrated ability to translate experimental results into models, tools, and research insights that advance cyber-physical system resilience.
