Machine Learning Engineer

Job Summary

Job Responsibilities:

• Design, build, deploy, and maintain production-grade machine learning solutions supporting demand forecasting, dynamic pricing, inventory optimization, and recommendation use cases.
• Partner with data scientists to convert experimental notebooks and prototypes into modular, tested, repeatable training and inference pipelines.
• Build and maintain feature engineering, model-training, batch-scoring, and real-time inference workflows using Python, Spark, SQL, Databricks, and MLflow.
• Implement MLOps practices for experiment tracking, model registration and versioning, automated testing, CI/CD, controlled promotion, rollback, and reproducibility.
• Define and monitor model and operational health measures, including model quality, drift signals, latency, failures, data quality, resource utilization, and compute cost.
• Validate model changes against reproducible datasets and established baselines, and assess downstream impact.
• Integrate model outputs with business applications and downstream platforms through reliable batch jobs, APIs, and secure data-access patterns.
• Optimize model architecture, feature processing, training, and inference for scalability, reliability, maintainability, and cost efficiency.
• Implement safeguards and fallback behavior so invalid data or failed optimization does not result in unsafe or misleading recommendations.
• Collaborate with stakeholders to translate revenue-management requirements into technical specifications, acceptance criteria, and measurable outcomes.
• Create and maintain technical documentation, model cards, runbooks, deployment plans, monitoring procedures, and retraining and rollback strategies.
• Ensure solutions comply with enterprise data governance, privacy, security, audit, and responsible AI requirements.

• Hands-on experience developing, deploying, and supporting machine learning models in production environments.
• Experience with cloud platforms, with a preference for Microsoft Azure.
• Experience with Apache Spark or Databricks and large-scale data processing.
• Knowledge of supervised learning, forecasting, optimization, feature engineering, model evaluation, and experiment design.
• Experience with software engineering practices including Git, code review, automated testing, CI/CD, configuration management, and environment promotion.
• Strong problem-solving, critical-thinking, communication, and cross-functional collaboration skills.
• Ability to work independently, manage changing priorities, and deliver in a fast-paced product environment.

Preferred Qualifications:

• Experience designing batch and real-time model-serving patterns and integrating model outputs into operational applications.
• Experience with model explainability techniques, statistical equivalence testing, A/B testing, and business-impact measurement.
• Experience with Azure services such as Synapse Analytics, Event Hubs, Azure Data Lake Storage, or related integration services.
• Experience with distributed ML libraries and frameworks such as scikit-learn, XGBoost, LightGBM, TensorFlow, PyTorch, or Spark MLlib.
• Experience implementing governed feature stores, lineage, access controls, audit trails, and model approval workflows.
