Security Researcher, AI Security

Everyone is racing to build on AI. Far fewer people are pulling it apart to see how it breaks. That's our work, and we get there before attackers do.

This role is part of Check Point's AI Security pillar. We research the AI systems the whole industry is rushing to adopt: the agents and frameworks heading into production, and the runtimes and infrastructure beneath them. The work is deep and hands-on. You'll find novel vulnerabilities, build them into full exploit chains, and follow research from a first lead to a working proof of concept.

We're growing the team, and we're looking for a Security Researcher who's at their best with a hard problem and no obvious way in.

Why you'll want to be here

We care about the work, and we care about each other. You'll get room to go deep, people worth learning from, and an early, hands-on look at the security of the tech everyone is betting on. If you've been waiting for a place to do the most interesting research of your career, let's talk.

Key Responsibilities

  • Research the security of AI systems end to end, from the agents and frameworks they're built on to the runtimes and infrastructure that run them
  • Take apart complex software and find where it breaks
  • Turn a vulnerability into a full, working exploit, not just a proof that the bug exists
  • Understand the defenses modern systems lean on, and how to get past them
  • Share what you find, through coordinated disclosure and conference talks

Qualifications

  • 4+ years in security research, vulnerability research, or a closely related field
  • A strong sense of how software works under the hood, whether that's a modern framework or the system underneath it
  • Comfortable reading complex code, and reverse engineering with IDA Pro or Ghidra when there's no source
  • Working knowledge of common vulnerability classes, from unsafe deserialization and logic flaws to memory corruption, and the experience to take one all the way to a working exploit
  • Excited about AI, and eager to get to its security problems first
  • Real curiosity, and the drive to go deep when the answer isn't obvious

Nice to have

  • Experience researching AI systems, agent frameworks, or the infrastructure behind them
  • Published research, whether CVEs, blog posts, or conference talks
  • A degree in computer science, mathematics, or engineering, or the hands-on experience to match
