• Proficiency in Python, including experience interacting with AI/LLM APIs and developing small-scale automation or orchestration components.
• Understanding of secure AI development practices, including safe prompt design and data-minimization principles.
• Experience implementing workflows that incorporate human-in-the-loop validation or approval mechanisms.
• Exposure to cybersecurity concepts such as detection engineering, incident response, threat intelligence, or security operations.
• Experience with AWS services such as Lambda, S3, CloudWatch, Step Functions, or DynamoDB.

Nice-to-Have Skills
