This role involves evaluating AI models' ability to generate secure code by identifying vulnerabilities, testing their security reasoning, and writing corrections when they fail. It suits security engineers and cybersecurity professionals who can spot weaknesses in authentication, cryptography, input handling, and secret management that automated tools miss.
Evaluate how AI models handle DevOps tasks such as CI/CD pipelines, infrastructure-as-code, and cloud operations. Identify failures in automation, security configurations, and deployment processes, then write correct solutions that a platform engineer would trust.
