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.

Solid understanding of query optimization, storage systems, and data pipelines.

Excellent problem‑solving skills, with the ability to design scalable solutions.

Strong communication and collaboration skills to work in cross‑functional teams.

Benefits —What you get —
