The ideal candidate combines strong machine learning expertise, software engineering best practices, and experience building scalable cloud-based ML systems.

What You Will Do

• Design, develop, and deploy machine learning models and solutions to solve complex business problems.

• Build and maintain production-grade ML pipelines for model training, evaluation, inference, and monitoring.

• Perform data transformation and feature engineering to create reliable and scalable input features for machine learning models.

• Implement model monitoring and drift detection frameworks to track data drift, feature drift, and model performance degradation in production.

• Develop scalable APIs and ML services using frameworks such as FastAPI to integrate ML models into business applications.

• Apply strong software engineering principles, including object-oriented programming, modular design, and code maintainability.

• Implement unit and integration tests using frameworks such as pytest to ensure reliability and maintainability of ML systems.

• Deploy and manage ML solutions in cloud environments, preferably Microsoft Azure.

• Work with large-scale enterprise data platforms such as Snowflake and collaborate with data engineering teams to build reliable data pipelines.

• Optimize model training and performance using distributed computing frameworks such as Ray and Dask.

• Use Optuna or similar tools for hyperparameter tuning and model optimization.

• Explore and implement Large Language Model (LLM) based solutions to address business problems such as knowledge retrieval, decision support, and workflow automation.

• Participate in code reviews, system design discussions, and continuous improvement of engineering standards.

• Collaborate closely with cross-functional teams including business, analytics, data engineering, and technology teams to deliver high-impact solutions.

Qualifications

• Master’s degree in Computer Science, Machine Learning, Data Science, Statistics, or a related quantitative field.

• 4+ years of experience building and deploying machine learning models and systems in production environments.

• Strong proficiency in Python for machine learning and software development.

• Strong understanding of object-oriented programming (OOP) and software design principles.

• Experience building APIs using frameworks such as FastAPI or similar Python web frameworks.

• Experience implementing unit testing using frameworks such as pytest.

• Strong understanding of data transformation, feature engineering, and feature pipeline development.

• Experience implementing model monitoring, drift detection, and model performance tracking in production environments.

• Experience working with cloud platforms, preferably Microsoft Azure.

• Experience working with data lake or modern data platforms such as Snowflake.

• Strong experience with machine learning frameworks such as scikit-learn, PyTorch, or TensorFlow.

• Experience working with large-scale datasets and building scalable ML pipelines.

• Familiarity with Large Language Models (LLMs) and their application to solve business problems.

Preferred Qualifications

• Experience with distributed computing frameworks such as Ray or Dask.

• Experience with Optuna or similar hyperparameter optimization tools.

• Experience with containerization technologies such as Docker.

• Experience working on end-to-end ML systems and production deployments across different domains.

Soft Skills

• Strong communication and presentation skills, with the ability to explain complex technical concepts to non-technical stakeholders.

• Ability to collaborate effectively across cross-functional teams including business, analytics, and engineering.

• Strong problem-solving mindset and ownership of end-to-end solutions.

• Ability to manage multiple priorities in a fast-paced, collaborative environment.

• Demonstrated ability to work with stakeholders to translate business problems into analytical solutions.
