• Manage SageMaker Model Registry with versioning, lineage tracking, and approval workflows for model governance
• Implement sophisticated endpoint deployment strategies including blue/green traffic routing, canary deployments, and A/B testing configurations
• Configure and maintain SageMaker Model Monitor for continuous data quality monitoring, model quality assessment, bias detection, and feature drift alerting
  
  

GenAI Model Lifecycle Management

• Implement automated evaluation pipelines for foundation model outputs with quality gates and human-in-the-loop review workflows
• Design prompt versioning systems integrated with model registry for reproducible GenAI deployments
• Monitor GenAI model performance including latency, cost per inference, hallucination rates, and guardrail trigger metrics
  
  

Model Lifecycle Automation

• Develop automated retraining trigger systems based on data drift, performance degradation, scheduled intervals, or manual triggers
• Implement evaluation gates as code with configurable thresholds for metrics (F1, precision, recall, AUC, etc.) before model promotion
• Build automated model promotion workflows from dev → staging → prod with approval gates and rollback capabilities
• Design rollback automation with traffic shifting strategies to quickly revert to previous model versions upon performance degradation
  
  

Training Data Engineering

• Build AWS Glue ETL pipelines for training corpus assembly, transformation, and feature engineering at scale
• Design dataset versioning systems using S3 + manifest files ensuring reproducibility and lineage tracking across model training runs

• Manage Amazon ECR repositories with lifecycle policies, image scanning, and vulnerability remediation workflows
• Implement bring-your-own-container (BYOC) patterns for SageMaker supporting custom frameworks and dependencies
• Optimize container startup times and resource utilization for cost-effective inference
  
  

ML Observability & Monitoring

• Design comprehensive CloudWatch dashboards for model health including accuracy, latency, throughput, error rates, and drift metrics
• Implement custom CloudWatch metrics for business-specific KPIs (e.g., clinical accuracy per condition, false positive rates for critical alerts)
• Build alerting systems for accuracy regression, data drift, concept drift, and model staleness with appropriate escalation paths
• Create observability frameworks that integrate with AWS X-Ray for end-to-end request tracing from API call through model inference
  
  

CI/CD for ML Artifacts

• Design and implement GitHub Actions or AWS CodePipeline workflows for automated ML artifact testing, validation, and deployment
• Build multi-stage promotion pipelines (dev → staging → prod) with automated testing gates and manual approval checkpoints
• Implement artifact versioning and lineage tracking for models, datasets, feature transformations, and deployment configurations
• Create integration testing frameworks for ML APIs including performance benchmarking and regression testing
  
  

Infrastructure & Compliance

• Collaborate with Full Stack AI/ML Engineers to define infrastructure requirements and translate them into production-grade AWS CDK constructs
• Implement HIPAA-compliant ML pipelines with appropriate encryption, access controls, audit logging, and data residency requirements
• Design multi-tenant ML infrastructure with tenant isolation, resource quotas, and cost allocation
• Ensure reproducibility and auditability of all ML experiments and deployments for regulatory compliance
