Title and Summary

Machine Learning Engineer II

Overview
As a Data Engineer on the Data Science & AI team, you will develop data products and solutions built on vast datasets gathered by retail stores, restaurants, banks, and other consumer-focused companies. The challenge will be to create high-performance algorithms, cutting-edge machine learning techniques, including deep learning, and intuitive workflows that enable our users to derive insights from big data, which in turn drive their businesses, all while maintaining a keen eye for data privacy. You will have the opportunity to create high-performance analytical solutions based on datasets containing billions of transactions, as well as front-end visualizations to unlock the value of big data.
You will also have the opportunity to develop innovative, data-driven analytical solutions, identify opportunities to support business and client needs quantitatively, and facilitate informed recommendations/decisions through activities such as AI-driven engineering solutions, automated data pipelines, and executing jobs in big data clusters using various execution engines like Spark, Hive, Impala, and others.
Role
In this role, you will:
• Build, deploy, and maintain production-level, data-driven applications and data processing workflows or pipelines.
• Work with testing frameworks and follow test-driven development (TDD) practices.
• Understand product requirements, engage with team members and customers to define solutions, and estimate the scope of work required.
• Utilize quantitative and qualitative problem-solving abilities to quickly learn and implement new technologies, and perform POCs to explore the best solutions for the problem statement.
• Work as a member of a matrix-based, diverse, and geographically distributed project team.
Qualifications
• You possess a degree or master's in Computer Science, Applied Mathematics, Engineering, or a related field.
• You have intermediate experience as a Machine Learning Engineer, Software Engineer, Data Engineer, and/or in a Data Solutions role.
• You have experience deploying machine learning models.
• High proficiency in Python and SQL.
• Experience with cloud-native big data frameworks (e.g., Hadoop, Yarn, Spark, Impala, Hive, NiFi, Airflow).
• Experience deploying solutions in cloud environments (e.g., Cloudera, Databricks, AWS) and using services (e.g., Tableau, Power BI, Databricks SQL dashboards).
• Experience working with engineering best practices (e.g., Git, Jira, DevOps).
• Solid understanding of data modeling, data monitoring, data dashboarding, database design, and data warehousing concepts.
