Horizon3.ai builds NodeZero, an autonomous pentesting platform that continuously tests enterprise infrastructure. This role anchors the company's AI/LLM attack research — a fast-growing niche as more production systems run on agents, RAG pipelines, and MLOps stacks that have brand-new attack surfaces.
What you'll do
- Research novel attacks against LLMs and agentic systems (prompt injection, tool-use exploitation, supply chain)
- Build automated attack modules that ship inside NodeZero
- Target MLOps, vector DB, and AI-platform infrastructure
- Stay current with OWASP Top 10 for LLMs, MITRE ATLAS, and the open research literature
What they're looking for
- Expert Python — including LLM-powered microservices and agentic workflows
- Deep familiarity with structured output, RAG patterns, and agent frameworks
- Offensive security background or strong appetite for it
- Comfortable working from open research and shipping the result
