  • Hands-on use of LLMs / AI models for security tasks, with the judgment to measure where they help and where they fail
  • Comfort with large datasets (SQL, BigQuery, or similar) to drive research and measure detection accuracy
  • Takes research ideas from prototype to production with minimal guidance
  • Clear written communication โ€” can explain a complex attack path to engineers and product managers
