Job Description

Description : Client is seeking an ML/AI Engineer to develop, fine-tune, and operationalize machine learning models that predict track nonconformities on the subway system. Working within a Google Cloud Vertex AI environment, you will leverage sensor data (vibration, audio, location) captured by Pixel phone hardware kits on revenue cars and ground-truth defect records from MTA''''s Hexagon system to build predictive models supporting the TrackInspect application.

Key Responsibilities:
  • Perform feature engineering on sensor and operational data to identify patterns correlated with documented track defects in Hexagon (HxGN)
  • Leverage and refactor existing prototype ML models for pilot-scale use; validate performance and suitability for production
  • Utilize Vertex AI Workbench to train, retrain, and version ML models; track experiments and metrics
  • Conduct hyperparameter tuning and model validation activities to optimize nonconformity prediction accuracy
  • Deploy trained models for daily batch inference; connect deployed models to batched sensor input pipelines
  • Implement model monitoring, alerting, and a continuous feedback loop from Track Inspector inputs captured in HxGN
  • Build and maintain CI/CD pipelines and multi-environment deployment strategy for current models
  • Build the BigQuery 'Predictions 63 User Friendly View' incorporating location attributes, prediction metadata, and feedback fields
  • Assess model results against known track defects within HxGN and present findings at model evaluation meetings with MTA
  • Proficiency in Python (scikit-learn, TensorFlow or PyTorch) and SQL
  • Hands-on Vertex AI experience (Workbench, training pipelines, model deployment)
  • Strong understanding of feature engineering, model validation, and hyperparameter optimization
  • Experience with time-series or sensor data (vibration, audio, or accelerometer signals a plus)
  • Familiarity with BigQuery as a data platform for ML pipelines
  • Experience with geospatial ML or GPS/LRS-based positioning models
  • Prior work in predictive maintenance, anomaly detection, or IoT sensor analytics
  • Google Professional ML Engineer certification
  • Understanding of transit or infrastructure asset management systems
  • Experience with Looker Studio or similar BI tools for ML output visualization
