Senior Data Engineer building trusted production ETL/ELT pipelines on GCP with BigQuery and orchestration.
IndiaWhat I'm looking for
I’m a Senior Data Engineer with 13+ years of experience designing, building, and operating production data pipelines and platforms. I deliver robust ETL/ELT on GCP—integrating sources across a ~300-project BigQuery estate—with SQL and Python, orchestrated via Cloud Composer (Airflow) and Keboola.
I focus on reliability, data quality, and governance as first-class concerns: I embed monitoring, reconciliation, and proactive data-quality checks in pipelines, and I run system/user-access and IAM/GCP audits with third-party auditors. I also leverage Terraform/Terragrunt, GitHub Actions, and Python automation to improve CI/CD and reduce toil, while leading 24×7 incident command and RCA with SLA/SLO tracking—plus mentoring (~17 engineers) and driving ~$245K cost savings.
