They’re only as good as the rules they know and the data they’re trained on. We’re the team that helps model these behaviors.

What You’ll Do

    – Engage in real-time “conversations” with AI to label fact vs. context vs. behavioral patterns.
    – Assess output for both factual accuracy and correct interpretation.

  • Stress-Test Models:
    – Deliberately “break” the AI, document failure modes, and propose fixes to our training workflows.

  • Iterate & Improve:
    – Collaborate with engineers and data scientists to refine prompts, evaluation criteria, and recovery strategies.
    – Track performance metrics and share insights in weekly reviews.
