The company offers exceptional compensation packages alongside a highly supportive, informal work culture dedicated to continuous professional development, including corporate sponsorship for international security conferences, team expeditions, and advanced training.

Located in Center District within short walking distance of the train station, offering regional flexibility to work out of a secondary hub in Tel Aviv (also train-accessible), under a accommodating hybrid model with partial remote work flexibility.

Position Overview-

• Vulnerability Researcher (iOS) joining a highly specialized, close-knit research cell focused on discovering sophisticated security flaws and structural anomalies in modern operating systems.
• Conducting deep-dive reverse engineering, static source code analysis, and dynamic instrumentation to audit low-level components and kernel architectures.
• Translating theoretical security flaws into actionable technical proofs-of-concept (PoCs) to validate systemic exposure.
• Collaborating with industry-leading peers to advance reverse engineering methodologies and keep pace with evolving modern hardware mitigation techniques.
• Core Stack & Ecosystem
• Vulnerability Research, Reverse Engineering, iOS Internals, ARM Architecture, Kernel Auditing, Exploitation Primitives, Mobile Security, Static/Dynamic Analysis (IDA Pro, Ghidra, LLDB), and C/Assembly programming.

Requirements-

• 4 years of proven professional experience dedicated to low-level vulnerability research or advanced reverse engineering – Mandatory
• Demonstrated track record of discovering at least one verified security vulnerability (e.g., zero-day discovery, CVE contribution, or deep-dive bug hunting validation) – Mandatory
• Deep technical expertise auditing mobile ecosystems, with specific research experience targeting iOS internals (e.g., IOKit, Objective-C/Swift runtimes, user-space daemons, or XNU kernel components) – Mandatory
• Strong fluency in low-level concepts, including memory corruption vectors, mitigation bypasses, and assembly debugging – Mandatory
