  • Establish data-quality checks, reconciliation processes, and monitoring.
  • Create clear technical documentation for data marts, pipelines, and analytical datasets.
  • Collaborate with technology, security, architecture, and production-support teams.
Required Qualifications

Experience:
  • Professional experience in data engineering, analytics engineering, software engineering, or a related technical field.
  • Advanced SQL skills, with the ability to write complex SQL from scratch.
  • Proficiency in Python for API integration, data extraction, automation, and transformation.
  • Hands-on experience designing and building data pipelines and analytical data models.
  • Experience integrating data from REST APIs or other third-party interfaces.
  • Hands-on experience with Google Cloud Platform and cloud-based data services.
  • Experience building data marts or other curated analytical data products.
  • Knowledge of dimensional modeling, data grain, and transformation logic.
  • Experience with data-quality testing, validation, logging, and monitoring.
  • Familiarity with source control and collaborative development practices.
  • Strong technical documentation and communication skills.
Preferred Qualifications
  • Experience building data products for Answer Engine Optimization, search analytics, or content intelligence.
  • Experience working with third-party marketing or analytics vendor APIs.
  • Experience with clickstream data, web-traffic data, or other event-level digital behavioral data.
  • Experience integrating digital marketing data with client, account, product, or campaign information.
  • Experience with modern analytics-engineering technologies, including dbt, dlt, and DuckDB.
  • Working knowledge of modern AI capabilities, such as LLM-based applications and retrieval-augmented generation.
  • Experience with business intelligence platforms such as Tableau, Looker, or Power BI.
  • Familiarity with GitHub, pull requests, CI/CD, and DevOps practices.
