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.

Requirements:

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

Advantage:

Experience working with LLMs, Deep Learning models, and ML pipelines
Experience with agentic workflows, autonomous agents, or multi-agent orchestration frameworks
Experience with static analysis, dynamic analysis, sandboxing, behavioral analysis, or binary instrumentation
Experience working in air-gapped or highly restricted environments

Why Cyberillium?:

By joining us, you’ll shape the DNA of a fast-growing company. Working with some of the best cyber talents in Israel, you will help us solve the ‘unsolvable’ problems for our highly technical clients through focused POCs, ideation, and collaboration with our research team.
