Full Spectrum Cyber AI Researcher

The Leidos Cyber Accelerator is seeking a hands-on applied researcher to design, execute, and automate real-world offensive security assessments while advancing ML-driven approaches to penetration testing. You will perform end-to-end automation of pentesting/red teaming (scoping → exploitation → post-exploitation → reporting), build repeatable tooling and test harnesses, and explore machine learning and reinforcement learning (RL) techniques for improving attack planning, prioritization, and autonomous decision-making. Primary Responsibilities: -Develop automation to support penetration tests and red-team style assessments across networks, endpoints, identity, and web apps; produce actionable, mission-aligned findings and remediation guidance. -Leverage agentic workflows to utilize common offensive tools: -Exploitation frameworks (e.g., Metasploit) -Pen-test distribution tools (e.g., common Kali Linux tools) -Fuzzing for vulnerability discovery (e.g., AFL / AFL++) -Apply and operationalize red-team knowledge bases and testing standards to summarize findings (e.g., NIST taxonomy, MITRE ATLAS/ATT&CK). -Research and prototype ML/RL approaches for security (e.g., attack-path selection, exploit prioritization, automated decision policies), and evaluate them via measurable experiments and test environments. -Build automation around offensive workflows (repeatable test harnesses, lab environments, tooling wrappers, and data collection for ML/RL experiments). -Collaborate with defensive engineers/researchers to translate findings into detections, mitigations, and secure-by-design improvements. Basic Qualifications: -Bachelor's degree and 5+ years relevant experience in offensive security, penetration testing, red teaming, vulnerability research, or closely related fields (additional years may substitute for degree). -Demonstrated hands-on experience using offensive security toolchains (e.g., Metasploit, Kali Linux) and modern recon/exploitation/post-exploitation workflows. -Experience with fuzzing or vulnerability discovery workflows (AFL/AFL++ or similar), including triage and root-cause analysis. -Strong programming/scripting skills (Python preferred; plus Bash). Experience using AI-assisted development tools (examples: coding agents, LLM copilots) to accelerate prototyping. -Working knowledge of ML fundamentals and practical experience implementing AI/ML experiments; familiarity with RL concepts. -Must be a US Citizen with the ability to obtain and maintain a Secret clearance. Preferred Qualifications: -Demonstrated applied research experience using modern AI techniques for automated or semi-automated penetration testing (e.g., attack-graph/decision-making approaches). -Reverse engineering and binary analysis experience (IDA Pro/Ghidra/radare2), exploit dev, and/or advanced fuzzing (instrumentation, harnessing, coverage-guided tuning). -Experience emulating adversary behaviors mapped to ATT&CK and converting results into durable security improvements. -Experience building repeatable lab environments and automation for security experimentation. -Ability to obtain and maintain a TS/SCI clearance.
