Key Responsibilities
### Core responsibilities (ordered by frequency and impact)
- •Design, build, and maintain ETL/ELT pipelines (daily)
- •Develop and run pipelines that move and transform data (e.g., ingest 200+ GB/day from APIs and S3). Ensure pipelines complete within agreed SLAs (typically 99.9% success rate). This keeps analytics accurate and available for weekly reports and ad-hoc queries.
- •Optimize query and storage performance (daily/weekly)
- •Tune SQL and table schemas to reduce query time by measurable amounts (target: cut median dashboard load time by 30%). Use partitioning, clustering, and columnar formats to lower compute costs and speed up user-facing reports.
- •Implement data modeling and schema design (weekly/strategic)
- •Create dimensional models (star/snowflake) and canonical schemas for business domains. Good models reduce downstream ETL complexity and speed up BI development, enabling analysts to build dashboards 40% faster.
- •Monitor, alert, and troubleshoot pipelines (daily)
- •Set up automated monitoring and alerts for failures, latency, and data drift. Investigate incidents within defined MTTR (e.g., 2 hours) and document root causes to prevent recurrence.
- •Manage infrastructure and costs (weekly/strategic)
- •Configure clusters, reserved instances, and query settings to control spend—aim to reduce monthly cloud spend by at least 10% while meeting performance targets.
- •Ensure data quality and governance (weekly/ongoing)
- •Implement validation tests, lineage tracking, and access controls. Maintain data accuracy for KPIs used by leadership in monthly executive reviews.
- •Collaborate and mentor (weekly/monthly)
- •Work with analysts, product managers, and data scientists to deliver features (e.g., deliver new customer cohort view within 2 sprints). Mentor junior engineers through code reviews and pair programming sessions.
Actionable takeaways:
- •Prioritize pipeline reliability: aim for 99.9% SLA.
- •Schedule weekly performance reviews to target 20–30% improvements.
- •Track cost metrics monthly and set concrete reduction goals.
