• Data Validation: Ensure accuracy, consistency, and completeness of datasets used in dashboards
• Query Performance: Identify inefficient queries and make basic improvements to support responsive dashboards
• Requirements Translation: Translate dashboard and reporting requirements into effective SQL queries

Basic Qualifications

• Bachelor's degree in computer science, Software Engineering, or related field with 4-8 years of experience; or Master's with 2-6 years
• US Citizenship
• Active TS/SCI with ability to successfully pass a Polygraph
• Strong SQL skills, including the ability to write advanced queries (joins, aggregations, subqueries, window functions)
• Experience working with enterprise relational databases (PostgreSQL, MySQL, Oracle, etc.)
• Background supporting analytics, dashboards, or reporting pipelines
• Comfortable working in Linux-based environments
• Proven ability to work independently on datacentric tasks and ensure data quality

Preferred Qualifications

• Experience with Grafana, Tableau, or similar visualization tools
• Exposure to CI/CD pipelines
• Experience working in Agile environments
