## Role details

## Job Summary

The Data Engineer is responsible for integrating CDS source systems into the AI platform by building the connectors and ingestion pipelines that reliably move source-system data into the platform.

## Key Responsibilities

    
- Build source-system integrations (webhooks $\rightarrow$ API Gateway/Lambda $\rightarrow$ EventBridge $\rightarrow$ SQS).
    
- Implement watermark/state tracking (DynamoDB) and periodic reconciliation to capture webhook delivery gaps without placing polling load on source systems.
    
- Onboard new CDS source systems onto the platform's ingestion pattern as the scope expands (e.g., Confluence, JIRA, and others across the CDS estate).
    
- Handle data migration activities where a source system needs backfilling into the platform (e.g., AWS DMS).
    
- Work with Knowledge Engineers to ensure ingested data meets quality and structural requirements.
