To support this delivery, they are looking for an experienced Cloud/DevOps Engineer to join an existing contractor and help accelerate the build of the integration layer ahead of a key June delivery milestone.

• Designing scalable event-driven architecture
• Processing large data feeds from S3 (CSV/JSON)
• Working with EventBridge and DynamoDB to manage event flows and state
