Core Responsibilities
Primary Functions
- Design, implement, and maintain robust ETL/ELT data pipelines using Python, SQL, and orchestration tools (e.g., Airflow, Prefect), ensuring timely ingestion and transformation of structured and semi-structured data from multiple sources.
- Build and maintain data models and schemas in cloud data warehouses (e.g., Snowflake, BigQuery, Redshift) and ensure they are optimized for query performance and downstream analytics.
- Author, review, and optimize complex SQL queries for data extraction, reporting, and analytics while following best practices for performance and maintainability.
- Develop reusable data ingestion patterns and libraries to standardize onboarding of new data sources, including APIs, event streams (Kafka/Kinesis), and batch file systems.
- Implement data validation, profiling, and automated testing (unit and integration tests) for pipelines to detect data anomalies and prevent regressions in production.
- Collaborate with data analysts and data scientists to translate business requirements into technical specifications, deliverables, and production-grade data sets.
- Monitor pipeline health and reliability using observability and monitoring tools (e.g., Datadog, Prometheus, CloudWatch) and implement alerting and incident response playbooks.
- Apply data governance practices including data lineage, schema versioning, and documentation to ensure data discoverability, privacy, and compliance with policies.
- Optimize and refactor existing ETL jobs and SQL logic to reduce runtime, cost, and resource usage while preserving accuracy and reliability.
- Implement CI/CD workflows for data pipeline deployment using Git, GitHub Actions, GitLab CI, or similar tooling to enable safe, repeatable releases to production.
- Assist in the migration and modernization of legacy on-premise data processes to cloud-native architectures and managed services.
- Participate in code reviews and share knowledge with peers to improve code quality and team-wide engineering standards.
- Create and maintain clear documentation, runbooks, and onboarding guides for datasets, pipelines, and platform components to support team scalability.
- Work with data security and compliance teams to implement data access controls, role-based permissions, and encryption where required.
- Contribute to the design and implementation of data catalogs and metadata platforms to support data discovery and governance initiatives.
- Support development of near-real-time data pipelines using streaming frameworks or managed streaming services, and ensure end-to-end throughput and latency requirements are met.
- Profile, clean, and enrich raw data to produce high-quality, analysis-ready datasets; implement transformations that capture business logic and KPIs.
- Collaborate with platform and infrastructure teams to provision, configure, and tune cloud resources (compute, storage, and networking) to meet pipeline SLAs and budget constraints.
- Troubleshoot production incidents, perform root cause analysis, and drive permanent fixes to prevent reoccurrence while communicating status to stakeholders.
- Create dashboards and lightweight metrics to measure data pipeline performance, data quality metrics, and business-impacting KPIs.
- Engage in sprint planning and agile ceremonies; estimate tasks, deliver incremental value, and maintain an accountable cadence of work.
- Stay current on modern data engineering trends, open-source tools, and cloud services; propose practical improvements and proof-of-concepts to enhance the data platform.
Secondary Functions
- Support ad-hoc data requests and exploratory data analysis to help business teams validate hypotheses and make data-driven decisions.
- Contribute to the organization's data strategy and roadmap by identifying technical debt, opportunities for automation, and cost-saving improvements.
- Collaborate with business units to translate data needs into engineering requirements, prioritizing based on impact and effort.
- Participate in sprint planning and agile ceremonies within the data engineering team.
- Mentor interns or junior engineers, providing code-level feedback and practical guidance on data engineering best practices.
