Job Description: ML/AI Data Scientist – Predictive Modeling 

Position Overview 

We are seeking an experienced ML/AI Data Scientist to design, build, train, evaluate, and deploy predictive models that solve complex business and operational problems. The ideal candidate combines strong statistical foundations with hands-on experience in data analysis, feature engineering, model development, and performance evaluation. 

This role is especially suited to someone who can build predictive solutions from the ground up and clearly explain the “what,” “why,” and “how” behind their analytical and modeling decisions to both technical and non-technical stakeholders. 

Key Responsibilities 

  • Translate business problems into well-defined machine learning and predictive modeling objectives. 
  • Collect, clean, transform, and analyze structured and unstructured data from multiple sources. 
  • Perform exploratory data analysis to identify trends, relationships, anomalies, biases, and data-quality issues. 
  • Develop predictive models from scratch, including data preparation, feature engineering, training, validation, testing, and optimization. 
  • Build and apply regression models for forecasting, estimation, risk scoring, pricing, demand prediction, and related use cases. 
  • Build and apply classification models for segmentation, fraud detection, churn prediction, recommendation, anomaly detection, and other decision-support applications. 
  • Select appropriate algorithms based on the problem type, data characteristics, business requirements, interpretability needs, and operational constraints. 
  • Compare baseline, linear, tree-based, ensemble, and other appropriate modeling approaches. 
  • Tune model hyperparameters and use appropriate cross-validation strategies to improve generalization. 
  • Experience building and deploying AI solutions using Natural Language Processing (NLP), Computer Vision, and sequence modeling techniques for text, image, video, and time-series data. 
  • Strong knowledge of deep learning architectures including RNNs, LSTMs, GRUs, CNNs, and Transformer-based models, with hands-on experience using TensorFlow or PyTorch. 
  • Ability to evaluate, optimize, and explain AI model performance, including model accuracy, robustness, bias detection, feature interpretation, and production monitoring. 
  • Evaluate model performance using relevant metrics such as RMSE, MAE, R², accuracy, precision, recall, F1 score, ROC-AUC, PR-AUC, log loss, calibration, and lift. 
  • Analyze model errors and identify opportunities for improving data quality, features, sampling strategies, and model assumptions. 
  • Assess model robustness, explainability, fairness, stability, and sensitivity to changing data patterns. 
  • Clearly communicate the rationale behind model selection, including why a particular model was chosen over alternatives. 
  • Explain technical results, assumptions, limitations, and trade-offs to product managers, business leaders, and other stakeholders. 
  • Document analytical methods, data sources, assumptions, experiments, model decisions, and results. 
  • Collaborate with data engineers, software engineers, product teams, domain experts, and business stakeholders to operationalize models. 
  • Support model deployment, monitoring, retraining, and continuous improvement in production environments. 
  • Stay current with developments in machine learning, statistical modeling, AI techniques, and responsible AI practices. 

Required Qualifications 

  • Bachelor’s or master’s degree in Data Science, Statistics, Mathematics, Computer Science, Engineering, Economics, or a related quantitative discipline. 
  • 3+ years of professional experience in data science, machine learning, predictive analytics, or a closely related field.

  • Strong knowledge of supervised learning workflows, including data splitting, cross-validation, feature selection, feature engineering, model tuning, and evaluation. 
  • Proficiency in Python and common data science libraries such as pandas, NumPy, scikit-learn, SciPy, and matplotlib or Seaborn. 
  • Strong SQL skills and experience querying, joining, aggregating, and analyzing data from relational databases. 
  • Experience working with missing data, outliers, imbalanced classes, categorical variables, high-cardinality features, and data leakage risks. 
  • Ability to select and justify appropriate evaluation metrics based on business objectives and model use cases. 
  • Experience explaining model behavior using techniques such as feature importance, partial dependence, SHAP, coefficients, permutation importance, or related methods. 
  • Excellent written and verbal communication skills. 
  • Ability to present complex analytical concepts clearly to audiences with varying levels of technical expertise. 

Preferred Qualifications 

  • Experience deploying machine learning models through APIs, batch pipelines, or cloud-based platforms. 
  • Familiarity with MLflow, Kubeflow, Airflow, Docker, Git, CI/CD, or similar tools. 
  • Experience with cloud platforms such as AWS, Microsoft Azure, or Google Cloud. 
  • Knowledge of time-series forecasting, survival analysis, recommender systems, or anomaly detection.

Ability to explain why a specific model is appropriate based on accuracy, interpretability, scalability, latency, data volume, feature relationships, regulatory requirements, and business impact. 

Statistical and Technical Expertise 

Strong understanding of statistical concepts and practical machine learning methods, with the ability to distinguish correlation from causation and identify modeling limitations. 

Data Understanding 

Ability to assess data quality, determine whether variables are meaningful, identify bias and leakage, and understand how data-generating processes affect model results. 

Communication 

Ability to communicate model assumptions, results, trade-offs, uncertainty, and limitations in clear and accessible language. 

Business Orientation 

Ability to connect technical modeling outcomes to measurable business goals, operational decisions, customer outcomes, or financial impact. 

Collaboration 

Ability to work effectively with engineering, product, operations, and leadership teams throughout the model lifecycle.
