Job responsibilities

• Build and enhance platform services for model registries, feature registries, promotion policies, and governance workflows
• Design and deliver capabilities for data preparation, annotation workflows, lineage, and audit trails
• Develop cloud-native services and application programming interfaces that scale across development and production environments
• Implement large language model-powered features (prompt design, agent workflows, tool integration, retrieval) with strong controls and evaluation practices
• Produce and maintain architecture and design artifacts; ensure solutions meet performance, resiliency, and security expectations
• Use approved AI-assisted development tools responsibly, validating outputs through code review, testing, and secure coding practices
• Partner with product and engineering stakeholders to prioritize roadmap items and improve platform usability
• Analyze operational metrics and user feedback to improve reliability, usability, and platform adoption
• Identify and remediate issues in systems and data; improve code quality, observability, and maintainability
