AI/ML Engineer - Application Development & Support

Position Overview

The AI/ML Engineer is a hands-on technical specialist responsible for designing, building, and operationalizing AI and machine learning capabilities within the MDM platform and its surrounding ecosystem. This role focuses on applying AI/ML to core MDM problems — entity matching, deduplication, data quality scoring, anomaly detection, and intelligent automation of data stewardship workflows.

This is not a research role — the AI/ML Engineer builds production-grade models and integrates them into the MDM platform's operational pipelines. The role operates under the "you build it, you support it" model, owning AI/ML features from experimentation through production deployment and ongoing monitoring.

The AI/ML Engineer works closely with the MDM Architect (who drives overall technical direction), the Engineering Manager (who drives delivery), and MDM/Integration developers (who build the platform and pipelines that AI/ML models plug into).

Key Responsibilities AI/ML Model Development & Integration

• Design, build, and train ML models for entity matching, deduplication, and record linkage across customer, supplier, contact, and item domains
• Develop probabilistic and deterministic matching algorithms that improve match accuracy over traditional rule-based approaches
• Build data quality scoring models that assess completeness, accuracy, consistency, and timeliness of master data records
• Develop anomaly detection models to identify data quality issues, unusual patterns, and potential duplicates in real-time data flows
• Design and implement intelligent survivorship logic using ML to determine optimal golden record attribute values from multiple sources
• Build NLP/text processing capabilities for entity name standardization, address parsing, and fuzzy matching
• Integrate AI/ML models into MDM platform workflows — matching, merging, stewardship routing, and exception handling
• Develop automated data classification and categorization models for incoming records
• Build recommendation engines for data stewards — suggest merge candidates, flag potential false positives, prioritize review queues
• Experiment with graph-based approaches for relationship discovery and network analysis across MDM entities

MLOps & Production Operations

• Deploy ML models to production environments with proper versioning, monitoring, and rollback capabilities
• Build and maintain ML pipelines for model training, validation, and deployment (e.g., MLflow, Kubeflow, SageMaker, Azure ML)
• Implement model monitoring — track prediction accuracy, data drift, concept drift, and model degradation over time
• Design A/B testing frameworks to compare model performance against rule-based baselines
• Build automated retraining pipelines triggered by performance degradation or data distribution changes
• Manage feature stores and feature engineering pipelines for MDM-specific features
• Optimize model inference performance for real-time matching scenarios (latency, throughput)
• Maintain model documentation including training data, hyperparameters, performance metrics, and decision thresholds

AI Platform & Agentic Workflows

• Design and build agentic AI workflows integrated with MDM processes (e.g., using AWS Bedrock, LangChain, or similar frameworks)
• Develop LLM-powered capabilities for data enrichment, entity extraction, and intelligent data validation
• Build AI-assisted stewardship tools that reduce manual review effort through intelligent automation
• Implement RAG (Retrieval-Augmented Generation) patterns for contextual data quality recommendations
• Evaluate and integrate foundation models and LLMs for MDM-specific use cases
• Design prompt engineering strategies and guardrails for production LLM integrations
• Build conversational interfaces for data stewards to query and interact with MDM data using natural language

Data Engineering for AI/ML

• Design and build feature engineering pipelines that extract ML-ready features from MDM, ERP, CRM, and data lake sources
• Build training data pipelines — extract, label, and version training datasets from production MDM data
• Implement data preprocessing, cleansing, and normalization pipelines specific to ML model inputs
• Collaborate with data lake and integration teams to ensure AI/ML pipelines have access to required data sources
• Design and maintain data schemas for ML feature stores and model input/output contracts

Production Support & Troubleshooting

• Own production support for AI/ML features — monitor model performance, investigate prediction failures, and resolve issues within SLAs
• Debug model prediction errors — trace through feature extraction, model inference, and post-processing to isolate root cause
• Analyze model logs and prediction outputs to identify systematic errors or bias
• Collaborate with MDM developers when AI/ML model outputs cause downstream data quality issues
• Perform root cause analysis when match/merge accuracy degrades and implement corrective actions
• Maintain runbooks for AI/ML model operations, retraining procedures, and incident response

Testing & Quality

• Design and execute model evaluation frameworks — precision, recall, F1, AUC for matching models
• Build automated test suites for model validation including edge cases, boundary conditions, and adversarial inputs
• Conduct A/B testing and champion/challenger experiments to validate model improvements
• Perform bias and fairness testing across different data segments and domains
• Participate in code reviews for ML code and provide feedback on data pipeline quality
• Maintain regression test datasets to ensure model updates don't degrade performance on known scenarios

Security & Compliance

• Working knowledge of data security, information security practices, and SOX compliance for AI/ML model changes in production
• Ensure PII/sensitive data handling compliance in model training and inference pipelines
• Implement model explainability and audit trails for compliance-sensitive matching decisions
