Quation Solutions Private Limited

Role Overview We are looking for a hands-on Data Scientist / Machine Learning Engineer who can translate business problems into scalable data science and ML solutions. The role requires strong analytical thinking, solid ML fundamentals, and the ability to productionize models in real-world environments. You will work closely with product, engineering, and business stakeholders to build, deploy, and maintain data-driven solutions across forecasting, recommendation, classification, and anomaly detection use cases. Key Responsibilities Data Science & Modeling Understand business problems and convert them into ML problem statements Perform EDA, feature engineering, and feature selection Build and evaluate models using: Regression, classification, clustering Time-series forecasting Anomaly detection and recommendation systems Apply model evaluation techniques (cross-validation, bias-variance tradeoff, metrics selection) ML Engineering & Deployment Productionize ML models using Python-based pipelines Build reusable training and inference pipelines Implement model versioning, experiment tracking, and retraining workflows Deploy models using APIs or batch pipelines Monitor model performance, data drift, and prediction stability Data Engineering Collaboration Work with structured and semi-structured data from multiple sources Collaborate with data engineers to: Define data schemas Build feature pipelines Ensure data quality and reliability Stakeholder Communication Present insights, model results, and trade-offs to non-technical stakeholders Document assumptions, methodologies, and limitations clearly Support business decision-making with interpretable outputs Required Skills Core Technical Skills Programming: Python (NumPy, Pandas, Scikit-learn) ML Libraries: XGBoost, LightGBM, TensorFlow / PyTorch (working knowledge) SQL: Strong querying and data manipulation skills Statistics: Probability, hypothesis testing, distributions Modeling: Supervised & unsupervised ML, time-series basics ML Engineering Skills Experience with model deployment (REST APIs, batch jobs) Familiarity with Docker and CI/CD for ML workflows Experience with ML lifecycle management (experiments, versioning, monitoring) Understanding of data leakage, drift, and retraining strategies Cloud & Tools (Any One Stack is Fine) AWS / GCP / Azure (S3, BigQuery, SageMaker, Vertex AI, etc.) Workflow tools: Airflow, Prefect, or similar Experiment tracking: MLflow, Weights & Biases (preferred) Good to Have Experience in domains like manufacturing, supply chain, fintech, retail, or consumer tech Exposure to recommendation systems, forecasting, or optimization Knowledge of feature stores and real-time inference systems Experience working with large-scale or noisy real-world datasets
