Job description

  • Offensive AI Research: Design and execute adversarial attacks against production AI/ML systems - including prompt injection and traditional vulnerabilities
  • Red Team Operations: Lead AI-focused red team engagements: threat model targets, develop attack chains, execute, and deliver actionable findings
  • Tool Development: Build, maintain, and document offensive security tooling for AI system testing - attack harnesses, fuzzing frameworks, automated vulnerability scanners, and agentic attack simulations
  • Vulnerability Research: Discover novel attack techniques against LLMs, multimodal models, agentic pipelines, and AI-integrated applications; contribute findings to the broader security community
  • Exploit Development: Develop proof-of-concept exploits for discovered vulnerabilities and work with engineering teams on remediation validation
  • Automation & Scale: Integrate offensive testing into pipelines and security review workflows so AI red teaming is continuous, not point-in-time
  • Knowledge Transfer: Document TTPs, author internal playbooks, and mentor other team members on AI attack techniques, * Builder Mentality - You default to automating and tooling your work, not doing it manually twice
  • Curiosity & Depth - You dig until you find the root cause; you're not satisfied with surface-level findings
  • Independent Operator - You can own a full engagement from scoping through remediation without heavy oversight
  • Adaptability - The AI attack surface changes weekly; you stay current and evolve your techniques accordingly
  • Collaborative - Offensive results matter only if they drive fixes; you work closely with defenders and engineers to close gaps

Requirements

Do you have experience in Vuls?, * 5+ years in offensive security, penetration testing, or red teaming

  • Strong software engineering skills - you write production-quality tools, not just scripts (Python required; Java, or JavaScript a plus)
  • Background in traditional appsec/web pentesting (Burp Suite, fuzzing, auth bypass) - many AI vulnerabilities are classic vulns in new wrappers
  • Cloud security experience across AWS, GCP, or Azure - including container/Kubernetes environments and cloud-hosted AI services
  • Ability to independently scope, execute, and report on offensive engagements
  • Strong written communication - clear, technically precise findings reports, * Hands-on experience attacking LLMs/GenAI systems, ML pipelines, APIs, or cloud-hosted AI services
  • Knowledge of common failure modes of AI agents and LLMs, risks and exploitation techniques
  • Experience with agentic AI frameworks, technologies and their attack surfaces
  • Familiarity with MLOps tooling, model serving infrastructure, and vector databases
