About The Position

We are seeking a highly skilled Senior Data Engineer with 8+ years of hands-on experience in enterprise data engineering, including deep expertise in Apache Airflow DAG development, dbt Core modeling and implementation, and cloud-native container platforms (Kubernetes / OpenShift). This role is critical to building, operating, and optimizing scalable data pipelines that support financial and accounting platforms, including enterprise system migrations and high-volume data processing workloads. The ideal candidate will have extensive hands-on experience in workflow orchestration, data modeling, performance tuning, and distributed workload management in containerized environments.

Requirements

  • 8+ years of hands-on experience in enterprise data engineering.
  • Deep expertise in Apache Airflow DAG development.
  • Deep expertise in dbt Core modeling and implementation.
  • Deep expertise in cloud-native container platforms (Kubernetes / OpenShift).
  • Extensive hands-on experience in workflow orchestration.
  • Extensive hands-on experience in data modeling.
  • Extensive hands-on experience in performance tuning.
  • Extensive hands-on experience in distributed workload management in containerized environments.

Responsibilities

  • Data Pipeline & Orchestration: Design, develop, and maintain complex Airflow DAGs for batch and event-driven data pipelines.
  • Implement best practices for DAG performance, dependency management, retries, SLA monitoring, and alerting.
  • Optimize Airflow scheduler, executor, and worker configurations for high-concurrency workloads.
  • dbt Core & Data Modeling: 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.
  • Cloud, Kubernetes & OpenShift: 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.
  • Performance & Reliability: 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.
  • Collaboration & Governance: 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.
