Senior Data Scientist (AI/ML/Predictive system maintenance)

Job Description:

We are looking for an experienced Data Scientist to support the design and implementation of an AI-driven Predictive Maintenance solution for industrial equipment.

The role will focus on analyzing historical and telemetry data, understanding equipment failure patterns, assessing data suitability for predictive use cases, developing machine learning models, and translating analytical findings into actionable maintenance insights.

Key Responsibilities:

• Analyze historical equipment, maintenance, operational, sensor and telemetry data to identify patterns associated with equipment degradation and failures.

• Work with domain experts to understand failure modes, their potential indicators, and whether available data provides sufficient predictive signals.

• Perform exploratory data analysis, data profiling, statistical analysis, correlation analysis and feature discovery.

• Assess data quality, completeness, frequency and predictive value before model development.

• Identify and engineer relevant features from time-series and operational data.

• Develop, train, validate and optimize machine learning models for failure prediction, anomaly detection and predictive maintenance.

• Evaluate appropriate modeling approaches for different equipment and failure scenarios.

• Define suitable model evaluation metrics and validate model performance against business and operational objectives.

• Develop approaches for handling imbalanced datasets and rare failure events.

• Collaborate with Data Engineers and solution architects on data preparation and model integration.

• Collaborate with equipment and maintenance SMEs to validate model outputs and ensure predictions are operationally meaningful.

• Support model explainability and provide transparency into the major factors contributing to predictions.

• Document experiments, assumptions, data limitations, model performance and recommendations.

• Contribute to the transition of validated models from experimentation or proof of concept into a production-ready solution.

Required Skills and Experience:

• 5+ years of experience in Data Science or Machine Learning, preferably including predictive maintenance, industrial analytics or IoT use cases.

• Strong proficiency in Python and common data science libraries such as Pandas, NumPy and Scikit-learn.

• Strong knowledge of machine learning, statistical analysis, time-series analysis, anomaly detection, classification, regression, feature engineering, and model validation and optimization.

• Experience working with sensor, telemetry, event and time-series datasets.

• Understanding of predictive maintenance concepts, including failure prediction, condition monitoring and equipment-health indicators.

• Experience dealing with missing, noisy, sparse and imbalanced industrial data.

• Strong SQL and data-analysis skills.

• Experience with model explainability and communicating model results to technical and business stakeholders.

• Ability to work closely with engineering and domain SMEs to translate physical equipment behavior into analytical hypotheses.

Nice to Have:

• Previous experience with manufacturing, industrial equipment, IoT, vending or cooling equipment, or connected-device analytics.

• Experience with cloud-based ML and data platforms.

• Experience with Azure Machine Learning, Databricks, MLflow or equivalent technologies.

• Knowledge of MLOps and production model monitoring.

• Experience with streaming or near-real-time telemetry.

• Understanding of Remaining Useful Life modeling and survival or reliability analysis.

• Experience with deep-learning approaches for time-series data.

Expected Contribution:

The Data Scientist will help determine which equipment failures can realistically be predicted from the available data, establish the relationship between telemetry signals and failure modes, and build validated predictive models capable of supporting proactive maintenance decisions.
