We are looking for an experienced Data Warehouse Software Engineer III to own, scale, and optimize our core Google Cloud Platform (GCP) data warehousing and ingestion ecosystem! 

In this role, you will be a key technical contributor responsible for architecting high-volume data ingestion pipelines into Google BigQuery, orchestrating complex workflow topologies in Apache Airflow (Cloud Composer), and maintaining the performance and reliability of our enterprise data warehouse. You will collaborate closely with cross-functional software, data, and analytics teams to integrate disparate commercial and government data sources into clean, highly available, and query-optimized data models.

This is an experienced engineering role requiring strong Python skills, deep expertise across the entire GCP analytics stack, and hands-on experience managing and upgrading production Airflow environments.

Key Responsibilities:

  • Data Warehouse & Pipeline Engineering: Architect, build, and maintain production-grade ELT/ETL data pipelines that stream and batch high-volume, complex datasets into Google BigQuery.

  • GCP Architecture & Optimization: Maintain and optimize core GCP data services (BigQuery, Cloud Storage, Cloud Functions/Run, Pub/Sub, IAM). Implement advanced BigQuery performance tuning (partitioning, clustering, slot management, and query cost control).
  • Python Engineering & Integrations: Develop high-performance Python scripts, API connectors, and automation tools for data extraction, schema validation, and third-party data integrations.
  • Data Quality & Integrity: Enforce strict data quality frameworks, monitoring, and automated alerting across all ingestion pipelines to ensure zero data loss and minimal latency.
  • Technical Leadership & CI/CD: Maintain infrastructure-as-code and CI/CD deployment pipelines for data workloads using Git. Assist in architectural reviews and mentor junior engineers on data warehousing best practices.

Job Requirements:

  • U.S. Citizenship: Must be a U.S. Citizen due to federal government contract requirements.
  • Software Engineering Experience: 4–7+ years of professional software development experience, with at least 3+ years focused heavily on data warehousing, cloud data pipelines, and data platform operations.
  • Advanced Python Mastery: Production-grade Python development skills for data processing, custom pipeline tooling, and API integrations.
  • Airflow Platform Operations: Hands-on experience with Apache Airflow (Cloud Composer preferred), including DAG architecture, troubleshooting, environment configuration, and platform version upgrades.
  • GCP Ecosystem Expertise: Deep experience with the Google Cloud analytics suite—specifically BigQuery, Cloud Storage (GCS), Cloud Composer, Pub/Sub, and Cloud Functions/Run.
  • BigQuery Optimization: Advanced understanding of BigQuery architecture, DDL/DML, partitioning, clustering, slot allocation, and query cost-control strategies.
  • DevOps & Version Control: Proficient with Git, CI/CD pipelines, and modern software development workflows.

Preferred Qualifications:

  • GCP Certification: Google Cloud Certified Professional Data Engineer (highly preferred).
  • High-Volume Data Experience: Experience working with multi-terabyte or billion-row datasets, unstructured web-scraped data, or streaming architectures.

•             Security & Compliance: Familiarity with government compliance frameworks, IAM policy design, and data encryption standards.

Form CC-305
Page 1 of 1

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
