Are you excited by the challenge of building intelligent, autonomous systems that deliver real-world impact? The Commerce Risk Analytics team at Microsoft is looking for a machine learning engineer to design, develop, and continuously improve a multi-agent AI Risk system that enables autonomous risk transaction review and decision-making. You'll be working at the intersection of large language models (LLMs), applied machine learning, and platform integration-building solutions that power scenarios from fraud prevention to customer support automation.

We're hiring across several focus areas, and your role will align with your expertise and interests:

• Autonomous Agent Development for Risk Decision - building LLM-based decision-making agents and advancing a multi-agent risk system
• AI Integration & MLOps - enabling scalable infrastructure, data pipelines, and operational excellence
• Quality & Integration - focusing on agent behavior testing, UI/UX integration, and platform reliability

Responsibilities:

As a machine learning engineer, you will:

• Design and optimize multi-agent AI architectures that enable autonomous risk assessment and decision-making at scale, leveraging agent collaboration to reduce huma manual effort and minimize false positive rates.
• Implement agentic ML infrastructure that automates the full model development lifecycle enabling continuous learning, adaptive optimization, and scalable risk decisioning.
• Build and evolve AI-driven solutions that improve the accuracy, speed, and adaptability of fraud detection across a wide range of Commerce scenarios.
• Develop infrastructure and MLOps pipelines to support continuous training, deployment, and monitoring
• Conduct rigorous behavior testing and validation, focusing on performance, safety, and real-world edge cases
• Integrate AI agents with Azure AI services, Microsoft Graph API, Power Platform, and internal systems
• Apply best practices in security, compliance, and privacy to all aspects of agent development
• Partner closely with product managers, engineers, and data scientists to translate complex business challenges into scalable technical solutions, ensuring alignment and impact across stakeholders
