• Participate in the RAIA to build and maintain standards and frameworks for Wintrust to use to review use cases and help the business develop use cases

• Analyze AI-specific security risks, including algorithmic bias, sensitive data exposure, PII leakage, and model poisoning (adversarial attacks), ensuring models remain resilient against manipulation

• Demonstrate agility by managing shifting security priorities and "other duties" as AI integration evolves, ensuring Wintrust's defense posture remains aligned with organizational needs

• Experience building and fine-tuning LLMs using frameworks like PyTorch or TensorFlow, with a focus on writing clean, scalable code for data preprocessing, embedding generation, and API integration while maintaining secure coding practices to prevent injection vulnerabilities
