Cybersecurity Engineer, Artificial Intelligence

The AI Cybersecurity Engineer will support technical security engineering for Wintrust's Responsible Artificial Intelligence Alliance (RAIA). This is a hands-on role focused on building robust defense-in-depth for AI systems, specializing in the secure integration of LLM frameworks and the mitigation of adversarial machine learning risks. You will collaborate across multi-disciplined teams to engineer automated security controls, perform red teaming on model deployments, and ensure that AI innovations remain resilient against evolving threat vectors.

What You'll Do

• Lead security assessments within the RAIA for Large Language Models (LLMs), Natural Language Models (NLMs), Small Language Models (SLMs), or other projects under the scope of Artificial Intelligence
• Participate in RAIA to review use cases based on value, complexity, feasibility, risks, compliance, and alignment with strategic goals
• Review AI architectural designs and usage within third-party products for compliance with security best practices, AI security frameworks, and regulatory requirements
• 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

• Bachelor's degree in Data Science, Computer Science, or AI preferred or equivalent experience
• 3-5 years of experience in the full Software Development Lifecycle
• Specific or relative experience in conducting security reviews of AI-driven applications to identify vulnerabilities in code, model logic, and data integration is a plus, but not necessary
• Understanding of machine learning architecture, including the ability to evaluate the security of training pipelines, inference engines, and API-driven workflows from a software engineering perspective
• Cybersecurity and/or Artificial Intelligence related certifications preferred

• Competitive pay and discretionary or incentive bonus eligible
• Comprehensive benefit package including medical, dental, vision, life, a 401k plan with a generous company match and tuition reimbursement to name a few
• Promote from within culture
