Security Researcher

Location: Planet Nine (IL)

Description

We are looking for a skilled Security Researcher to join our research team and work on advanced cybersecurity projects across a wide range of technologies and environments. You’ll research complex systems, identify and analyze vulnerabilities and attack vectors, develop PoCs, and build tools and methodologies to support hands-on security research.

Our projects span multiple domains, including software and security products, critical infrastructure, embedded and communication systems, cloud environments, and emerging technologies such as AI and LLM based systems. You’ll work alongside experienced researchers, take ownership of complex research missions, and contribute to high-impact projects for customers in Israel and internationally.

Responsibilites

• Security & Vulnerability Research – Conduct hands-on security research across complex products, applications, systems, and technologies.
• Vulnerability Discovery & Analysis – Identify vulnerabilities and attack vectors, analyze their root cause and security impact, and develop practical PoCs.
• Research Methodology – Explore unfamiliar technologies, map attack surfaces, define research approaches, and lead investigations from initial exploration through validated results.
• Technical Analysis – Perform static and dynamic analysis, code review, protocol analysis, or reverse engineering according to project needs.
• Documentation & Collaboration – Document research methodology and findings, collaborate with other researchers and engineering teams, and present technical results internally and to customers.
• Ownership – Take end-to-end ownership of complex research tasks while working as part of an experienced multidisciplinary research team.

Requirements

Must Have

• 5+ years of hands-on experience in security research or offensive security.
• 5+ years experience in reverse engineering using tools such as IDA Pro, Ghidra, or Binary Ninja (Hands-On).
• Proven hands-on experience in vulnerability discovery, security analysis, and PoC development.
• Strong programming and scripting experience (C/C++, Python, or equivalent).
• Strong ability to independently research complex and unfamiliar systems and technologies.
• Ability to work within a team while leading complex research missions end-to-end.

Nice to Have

• Experience with low-level vulnerability research, exploit development, or fuzzing.
• Knowledge of embedded systems, firmware, OS internals, or communication protocols.
• Experience with cloud, application, or AI/LLM security research.
• Familiarity with secure code review, security architecture review, or threat modeling.
• Prior contributions to security research publications, CVEs, or responsible vulnerability disclosures.
