• Implement ELT/ETL processes to clean, validate, transform, and model data into trusted datasets.
• Build and maintain machine-learning–ready datasets and feature pipelines that support experimentation and production models.
• Ensure data quality, freshness, and reliability through monitoring, alerting, and automated validation checks.
• Partner with analytics and business teams to define data requirements, metrics, and reporting outputs.
• Support downstream data consumption for BI tools, dashboards, operational reporting, and partner data exports.
• Apply best practices around data governance, security, access controls, and documentation.
• Collaborate cross-functionally to deliver scalable, maintainable data solutions aligned with business priorities.
• Continuously improve performance, cost efficiency, and reliability of the data platform.

Qualifications

Required

• Bachelor’s degree in Computer Science, Data Engineering, Engineering, or a related field (or equivalent experience).
• 4+ years of experience in data engineering or related roles.
• Strong proficiency in Python and SQL.
• Hands-on experience building and operating data pipelines and workflows.
• Experience with modern data platforms (data lakes, data warehouses, or lakehouse architectures).
• Familiarity with orchestration tools (e.g., Airflow, Dagster, Prefect) and data transformation frameworks.
• Solid understanding of data modeling, schema design, and data quality best practices.
• Experience integrating data from APIs and third-party systems.
• Strong problem-solving skills and ability to work independently in a fast-paced environment.
• Excellent communication skills and ability to work with both technical and non-technical stakeholders.

Preferred

• Experience supporting machine learning workflows (feature engineering, training datasets, or ML pipelines).
• Familiarity with cloud platforms (AWS, Azure, or GCP).
• Experience with streaming or near–real-time data pipelines.
• Knowledge of data governance, security, and compliance best practices.
• Prior experience in financial services, fintech, or regulated data environments.
