• Onboard enterprise datasets into Palmos, including ingestion, transformation, and validation of data assets
• Build, test, and maintain scalable data pipelines and data architectures that support enterprise controls and analytics use cases
• Build buisness controls algorithms for communications data to identify anomalies
• Build data completeness and integrity controls for the pipelines
• Apply data engineering best practices for performance optimization, reliability, and maintainability
• Use SQL extensively and work with both relational and NoSQL data stores
• Partner with producers to understand data requirements and translate them into production-ready solutions
• Apply SDLC practices including CI/CD, testing, and operational monitoring to ensure pipeline stability
• Contribute to reusable frameworks and standards to accelerate onboarding and pipeline delivery
• Identify data issues, anomalies, and optimization opportunities to improve data quality and performance
• Leverage enterprise-authorized AI coding assist tools within the work environment to improve code quality, delivery speed, and productivity across complex deliverables (e.g., code generation/refactoring, unit test creation, documentation), while validating outputs through peer review, automated testing, and secure coding standards; contribute learnings and reusable patterns to improve broader team effectiveness
