- Implement best practices for DAG performance, dependency management, retries, SLA monitoring, and alerting
- Optimize Airflow scheduler, executor, and worker configurations for high-concurrency workloads
- Lead dbt Core implementation, including project structure, environments, and CI/CD integration
- Design and maintain robust dbt models (staging, intermediate, marts) following analytics engineering best practices
- Implement dbt tests, documentation, macros, and incremental models to ensure data quality and performance
- Optimize dbt query performance for large-scale datasets and downstream reporting needs
- Deploy and manage data workloads on Kubernetes / OpenShift platforms
- Design strategies for workload distribution, horizontal scaling, and resource optimization
- Configure CPU/memory requests and limits, autoscaling, and pod scheduling for data workloads
- Troubleshoot container-level performance issues and resource contention
- Monitor and tune end-to-end pipeline performance across Airflow, dbt, and data platforms
- Identify bottlenecks in query execution, orchestration, and infrastructure
- Implement observability solutions (logs, metrics, alerts) for proactive issue detection
- Ensure high availability, fault tolerance, and resiliency of data pipelines
- Work closely with data architects, platform engineers, and business stakeholders
- Support financial reporting, accounting, and regulatory data use cases
- Enforce data engineering standards, security best practices, and governance policies
Experience
- 10 years of professional experience in data engineering, analytics engineering, or platform engineering roles
- Proven experience designing and supporting enterprise-scale data platforms in production environments
- Expert-level Apache Airflow (DAG design, scheduling, performance tuning)
- Expert-level dbt Core (data modeling, testing, macros, implementation)
- Strong proficiency in Python for data engineering and automation
- Deep understanding of Kubernetes and/or OpenShift in production environments
- Extensive experience with distributed workload management and performance optimization
- Strong SQL skills for complex transformations and analytics
- Experience running data platforms on cloud environments
- Familiarity with containerized deployments, CI/CD pipelines, and Git-based workflows
- Experience supporting financial services or accounting platforms
- Exposure to enterprise system migrations (e.g., legacy platform to modern data stack)
- Experience with data warehouses (Oracle)
