Job Summary

We are looking for an experienced Senior Security Researcher to join Idira Labs, a product-focused security research team dedicated to strengthening the security of Idira products.

In this role, you will lead advanced penetration testing and vulnerability research across cloud, web, mobile, and AI-enabled systems. You will combine deep manual research with secure code review, automation, and AI-assisted techniques to uncover complex vulnerabilities and drive meaningful security improvements across the product portfolio.

You will own research initiatives from initial threat modeling and attack-surface analysis through exploitation, reporting, and remediation validation, partnering closely with software architects and engineering teams to translate research findings into resilient product design.

Key Responsibilities

• Lead proactive penetration testing and vulnerability research across Idira products, services, and supporting architectures.
• Discover, validate, and demonstrate the impact of complex vulnerabilities using manual research, code review, dynamic analysis, and automated techniques.
• Conduct security evaluations of AI architectures, LLM-powered applications, agentic frameworks, tool integrations, and AI-assisted application pipelines.
• Own security research projects end to end—from defining scope and attack scenarios to communicating findings and validating remediation.
• Build and customize scripts, tools, and automation that improve research coverage, repeatability, and scale.
• Partner with Engineering and Architecture teams to translate findings into actionable mitigations, secure design patterns, and long-term product improvements.
• Evaluate emerging offensive security techniques, AI-assisted research tools, and automated exploitation frameworks.
• Drive innovative security research throughout the year and share relevant insights internally and, where appropriate, with the broader security community.

Qualifications

Required Qualifications

• 5+ years of hands-on experience in security research, penetration testing, offensive security, or product security.
• Proven experience performing security assessments of cloud, web, and mobile applications.
• Strong secure code-review skills, including the ability to identify vulnerabilities, understand exploitability, and assess business impact.
• Hands-on experience with offensive security tools, SAST and DAST technologies, and automated vulnerability-discovery frameworks.
• Experience using AI coding assistants or AI-assisted security tools as part of research and testing workflows.
• Strong security fundamentals and the ability to develop custom scripts, tools, or proof-of-concept exploits.
• Familiarity with AI threat modeling, LLM and agent security, prompt-injection techniques, and AI safety evaluation methodologies.
• Demonstrated ability to independently drive complex research projects in a fast-moving product environment.
• Excellent written and verbal communication skills in English and Hebrew.

Preferred Qualifications

• Offensive Security certifications such as OSCP, OSWE, OSEP, OSCE3, or equivalent.
• Bachelor’s degree in Computer Science, Cybersecurity, or a related technical field, or equivalent practical experience.
• Experience in a leading military technology or intelligence unit, or equivalent advanced industry experience.
• A track record of security publications, technical blog posts, open-source tools, or presentations at security conferences.
• Demonstrated security research impact through CVE disclosures, bug-bounty findings, or other responsibly disclosed vulnerabilities.
