GCP Data Analyst - BigQuery (USA)

Key Responsibilities:-

• Write, optimize, and execute complex SQL queries in BigQuery to validate data accuracy, identify inconsistencies, and support analytics and reporting.
• Analyze large datasets to assess data quality, compare trends across systems, and surface anomalies or unexpected behaviors.
• Utilize advanced BigQuery features such as authorized views, materialized views, UDFs, partitioned tables, and joins to support scalable, high-performance analysis.
• Use Python (including data frames and relevant libraries) for exploratory analysis, data manipulation, and supporting validation workflows.
• Support time series analysis and, where applicable, anomaly detection using SQL or Python-based approaches.
• Assist with load/transform validation to ensure reliability and accuracy in data pipelines.
• Collaborate with engineering teams to understand data pipelines, with basic ability to read and interpret Java or Scala code when needed.
• Perform side-by-side comparisons of data across systems to ensure consistency during and after migrations.
• Maintain basic familiarity with orchestration tools such as Airflow (Composer) to follow pipeline logic and collaborate effectively with engineering.
• Work within the GCP environment, leveraging cloud tools and services to support analysis, troubleshoot issues, and navigate cloud-based workflows.
• Clearly communicate analytical findings and data quality issues to cross-functional stakeholders to support decision-making.

Qualifications:-

• Bachelor’s degree in Computer Science, Data Science, Engineering, or a related field.
• 5+ years of experience in data analyst or analytics engineering roles with strong BigQuery, SQL, and Python skills.
• 5+ years of experience building and operating solutions on Google Cloud Platform (GCP).
• Strong ability to write and optimize SQL queries to validate data, analyze trends, and detect inconsistencies.
• Proficient in Python, including use of data frames and common analytical libraries.
• Experience with advanced BigQuery features such as authorized views, materialized views, UDFs, partitions, and time series analysis.
• Strong analytical skills and experience validating data across systems during migrations and ongoing operations.
• Basic ability to read and understand Java or Scala code to support engineering collaboration.
• Familiarity with Airflow (Cloud Composer) to interpret and trace data pipeline workflows.

Nice to have:-
