Hex-Rays, the company behind IDA Pro (the industry-standard reverse-engineering platform), is seeking an R&D Engineer to design and build AI agents for security research. You will work at the intersection of AI and offensive security in a small, senior team, combining practical security expertise with strong engineering judgment to solve complex, open-ended problems.
Key Responsibilities:
- Design and build AI agents for security research applications
- Bring hands-on security expertise to inform the team's engineering approach and technical decisions
- Develop and improve software and tooling that supports AI-driven security research
- Evaluate results critically, identify limitations, and improve quality and reliability of systems
- Own complex, open-ended problems end-to-end, from initial experimentation through working solution
- Work independently and effectively within a small, senior team environment
The role sits at the frontier of AI and security research, tackling problems where answers haven't been written yet. You'll have real ownership and direct input into what the team builds, helping shape how the next generation of security research gets done.
Requirements:
- Hands-on cybersecurity experience in security research or offensive security (reverse engineering, vulnerability research, or exploit development)
- Experience with AI agents and LLMs, OR clear aptitude and strong enthusiasm for working with them (prompting, tool use, orchestration, evaluating and improving agent output)
- Strong engineering ability and sound technical judgment
- Practical approach to hard, ambiguous problems; ability to determine what matters and build working solutions
- Independence and effectiveness in small, senior team settings; ownership of work while advancing shared goals
Nice to Have:
- Deeper experience building agentic or LLM systems, including multi-agent setups, tool-calling frameworks, and evaluations
- Strong exploit-development background with public track record (CVEs, CTF achievements, talks, technical write-ups, tools)
- Deep reverse-engineering experience with IDA or similar tools; confidence working in disassembly and decompiled code
- Specialist knowledge of kernels, browsers, mobile/Android, firmware, or embedded systems
- Relevant technical experience in Israeli intelligence technology units (8200, 81) or Ministry of Defense
