Senior Software Engineer - Cyber Domain

Cyberillium offers high-end security research and R&D services for customers who want to build secure products. We conduct in-depth research, architecture design, and low-level development across a wide range of technologies. Founded by an elite group of Israeli security researchers, we deliver cutting-edge cyber solutions to enterprises of all sizes and the Israeli government.

Alongside our services, we are building a next-generation Agentic AI Malware Analysis and Threat Intelligence System designed for high-security, air-gapped environments.

We are looking for a Senior Software Engineer with specialization in the Cyber Domain to become a key technical player in this effort.

In this role, you will be responsible for developing and overseeing the integration of advanced AI (LLMs, multi-agent orchestration) with traditional malware analysis tools to deliver highly automated reverse engineering, behavioral analysis, and threat attribution. You will work hands-on across the system, helping shape technical decisions, guiding other engineers, collaborating directly with stakeholders, and translating advanced concepts into reliable production-grade capabilities.

• Drive the end-to-end development of a complex, multi-component system, including LLM pipelines, agent orchestration layers, static and dynamic analysis engines, and local CTI knowledge base integration
• Design and implement systems for air-gapped/on-prem deployments, including model lifecycle management, secure update mechanisms, data isolation, and system hardening
• Lead technical discussions and contribute to architectural decisions across the platform
• Review designs, code, and technical implementations to ensure quality, maintainability, and reliability
• Drive complex technical initiatives from concept through production deployment
• Contribute to the evolution of platform capabilities based on customer requirements and operational feedback
• Mentor and support other developers while maintaining a high engineering standard

Skills and Experience

• 5+ years of hands-on software engineering experience in C++ and/or Rust
• Cybersecurity background in at least one of the following: Malware Analysis, Reverse Engineering, Vulnerability Research, or adjacent cybersecurity domains
• Familiarity with reverse engineering tools such as IDA, Frida, Ghidra, or similar
• Strong debugging, problem-solving, and system design capabilities
• Ability to operate across the full development lifecycle, from technical design and architecture discussions through implementation and delivery
• Experience leading technical initiatives and driving projects independently
• Strong communication skills in both Hebrew and English
