Job Description

We’re seeking a highly skilled, execution-focused Senior Data Scientist with a minimum of 5 years of experience. This role demands hands-on expertise in building, deploying, and optimizing machine learning models at scale, while working with big data technologies and modern cloud platforms. You will be responsible for driving data-driven solutions from experimentation to production, leveraging advanced tools and frameworks across Python, SQL, Spark, and AWS. The role requires strong technical depth, problem-solving ability, and ownership in delivering business impact through data science.

Responsibilities

  • Design, build, and deploy scalable machine learning models into production systems.
  • Develop advanced analytics and predictive models using Python, SQL, and popular ML/DL frameworks (Pandas, Scikit-learn, TensorFlow, PyTorch).
  • Leverage Databricks, Apache Spark, and Hadoop for large-scale data processing and model training.
  • Implement workflows and pipelines using Airflow and AWS EMR for automation and orchestration.
  • Collaborate with engineering teams to integrate models into cloud-based applications on AWS.
  • Optimize query performance, storage usage, and data pipelines for efficiency.
  • Conduct end-to-end experiments, including data preprocessing, feature engineering, model training, validation, and deployment.
  • Drive initiatives independently with high ownership and accountability.
  • Stay up to date with industry best practices in machine learning, big data, and cloud-native deployments.
