Job Description:

The Prompt Injection Specialist will design and execute structured adversarial prompt testing against a LLM chatbot. The focus is exclusively on prompt-layer vulnerabilities: jailbreaks, direct and indirect prompt injection, instruction override, and boundary attacks. This is not a cybersecurity or infrastructure penetration testing role.

Job Responsibility:

  • Design and execute structured adversarial prompt testing against a LLM chatbot
  • Focus exclusively on prompt-layer vulnerabilities: jailbreaks, direct and indirect prompt injection, instruction override, and boundary attacks

Requirements:

  • Hands-on experience with LLM prompt injection, jailbreaking, and adversarial prompt design
  • Strong understanding of chatbot architectures, system prompt structures, and guardrail mechanisms
  • Familiarity with OWASP LLM Top 10, MITRE ATLAS, and relevant adversarial ML frameworks
  • Experience designing structured prompt test sets with coverage metrics
  • Ability to define failure taxonomies and severity classification for prompt-layer attacks
  • Proficiency with common LLM APIs and chat interfaces (OpenAI, Anthropic, Azure OpenAI, or equivalent)
