• Design scalable data models and schemas that support both transactional and analytical workloads.
• Orchestrate and schedule data workflows using tools such as Apache Airflow, Dagster, or Prefect.
• Implement data quality checks, validation, and monitoring to ensure accuracy, completeness, and reliability of data across the platform.
• Optimize query performance and pipeline efficiency for large-scale datasets.
• Collaborate with front-end team members to present data in a clear and user-friendly format, enhancing the product's user experience.
Qualifications:
• Ability to own and manage concurrent initiatives, demonstrating effective judgment in prioritization and time management.
• Driven, self-managed, capable of conceiving and implementing solutions on your own and with a team.
• A strong desire to continuously improve and learn new technologies in a fast-paced Agile development environment.
• Excellent analytical and problem-solving skills, effective communication, attention to detail and high-quality work.
• Strong technical documentation ability to support the development process, including data flow and pipeline documentation.
• Effective communication and collaboration with designers, developers, and product managers.
• Ability and interest in mentoring junior and mid-level engineers to foster their growth and development.
Required Education / Experience:
• Bachelor's Degree in Computer Science, Computer Engineering or related field.
• 7+ yrs professional software engineering experience using Python, including at least 3 years focused on data engineering or ETL pipeline development.
• Experience building applications on cloud computing platforms such as AWS, Azure, GCP, using container technologies such as Docker and Kubernetes.
• Expert proficiency in SQL, including query optimization and performance tuning.
• Hands-on experience designing and building production data pipelines using Python data libraries (e.g., pandas, PySpark).
• Strong understanding of data modeling concepts, including relational and dimensional modeling.
Preferred Education/Experience:
• Experience with various database architectures including relational (PostgreSQL) and graph (Neo4j).
• Experience building GraphQL backends.
• Experience with workflow orchestration tools such as Apache Airflow, Dagster, or Prefect.
• Experience with distributed data processing frameworks such as Apache Spark.
• Experience with streaming or event-driven data technologies such as Kafka, Kinesis, or change data capture (CDC).
• Experience with cloud data warehouses and lakes such as Snowflake, Redshift, Databricks, or S3-based lakes using Parquet/Delta formats.
