Expertise in AWS-native AI/ML infrastructure (SageMaker, S3, Lambda, Step Functions, API Gateway)
Proven system design skills, balancing latency, scalability, experimentation, and cost
Familiarity with the full AI lifecycle: prototyping, evaluation, deployment, monitoring, and optimization
Experience leading cross-functional teams and mentoring engineers or data scientists
Product-oriented mindset: ability to translate AI capabilities into solutions that deliver real user value
Advanced degree (Masters or PhD) in Data Science, Computer Science, or a related field preferred
Bonus: experience in fraud detection, fintech, risk management, or security domains
