DescriptionAre you passionate about building AI-enabled capabilities that accelerate reverse engineering and vulnerability research?
Do you want to design systems that can reason, plan, use tools, and rapidly demonstrate mission impact?
If so, we want you to join our group of offensive cyber experts! We are seeking reverse engineers, vulnerability researchers, and cyber capability developers who know how to leverage modern AI technology to solve complex cyber challenges. This is not a traditional software development role! It requires designing AI-native architectures, orchestrating tool-using agents, and rapidly iterating on prototypes that demonstrate functional, outcome-driven impact. We work in a dynamic, mission-driven environment where our efforts have real-world impact. Collaboration is at the heart of our culture, and we value multidisciplinary perspectives, curiosity, and continuous learning. We encourage our staff to explore emerging technologies, share knowledge, and deepen their expertise as they take on some of the nation's toughest challenges.
As a member of our group, you will...- Reverse engineer mission-relevant systems and develop innovative exploits
- Design and implement agentic AI systems to automate vulnerability research, reverse engineering, and capability development workflows
- Collaborate with government sponsors and operators to build mission-aligned capabilities
- Integrate large language models, AI services, external tools, and data sources into full-stack applications for cyber use cases
- Propose groundbreaking ideas for internal and external funding opportunities
- Mentor teammates in the art and science of using AI to enhance offensive cyber capability development
- Share knowledge by clearly articulating ideas through papers and presentations to team members, APL management, and government decision makers
QualificationsYou meet our minimum qualifications for the job if you...- Have a Bachelor's degree in Computer Engineering, Computer Science, Electrical Engineering, or a related field
- At least 5 years of relevant experience
- Have experience developing agentic AI systems including planning, memory, tool use, and multi-step reasoning workflows
- Are skilled with software debuggers and static analysis tools such as Ghidra
- Have experience with modern AI development platforms such as Claude Code, Gemini, Codex, or Copilot
- Are proficient with one or more programming languages
- Understand Unix/Linux operating systems
- Love solving puzzles and have experience persevering through technical challenges
- Hold an active TS/SCI clearance and can ultimately obtain a TS/SCI+Polygraph clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information; eligibility requirements include U.S. citizenship.
You'll go above and beyond our minimum requirements if you...- Previously held dynamic technical leadership roles and have demonstrated mentoring experience
- Have experience applying AI systems to reverse engineering, vulnerability research, or exploit development
- Have experience designing production-grade agent workflows, including orchestration, evaluation, guardrails, observability, and reliability testing
- Have familiarity with virtualization, emulation, sandboxing, or automated analysis environments
- Have knowledge of advanced vulnerability discovery tools
- Possess an active TS/SCI clearance with full scope polygraph
