Key Responsibilities

1. Machine Learning Model Development

• Design, develop, train, and evaluate machine learning models for prediction, classification, recommendation, or automation use cases.
• Apply supervised, unsupervised, and deep learning techniques as appropriate.
• Perform feature engineering, model tuning, and validation to improve accuracy and performance.

2. Productionisation & Deployment

• Deploy ML models into production using scalable, reliable architectures.
• Build and maintain APIs or batch pipelines for model inference.
• Monitor model performance, data drift, and retraining needs.

3. Data Engineering & Pipelines

• Collaborate with data engineers to design efficient data ingestion and transformation pipelines.
• Work with structured and unstructured data from databases, APIs, and data lakes.
• Ensure data quality, reproducibility, and versioning.

4. MLOps & Automation

• Implement MLOps practices including CI/CD for ML, model versioning, and experiment tracking.
• Use tools such as MLflow, Kubeflow, SageMaker, Vertex AI, or Azure ML.
• Automate model training, testing, deployment, and monitoring workflows.

5. Cloud & Infrastructure

• Build ML solutions on cloud platforms such as AWS, Azure, or GCP.
• Use containerization and orchestration tools (Docker, Kubernetes).
• Optimize compute costs and performance for training and inference workloads.

6. Collaboration & Stakeholder Engagement

• Work closely with Data Scientists, Product Managers, Software Engineers, and Analysts.
• Translate business requirements into scalable ML solutions.
• Communicate model behaviour, limitations, and results clearly to non-technical stakeholders.

7. Research & Continuous Improvement

• Stay current with advancements in machine learning, AI, and data science.
• Evaluate new algorithms, tools, and frameworks for potential adoption.
• Contribute to best practices, documentation, and knowledge sharing.
