• Monitor platform health, availability, and performance; proactively resolve issues

• Implement, maintain, and monitor integrations between business systems using Celigo (iPaaS) and API-based connections
• Design and manage data flows between NetSuite, Shopify, Salesforce, third-party logistics providers, and other systems
• Build transformation logic, error handling, and alerting for integration pipelines
• Troubleshoot and resolve integration failures with urgency and rigor
• Document integration architecture, data mappings, and runbooks

• Manage AWS infrastructure including EC2, S3, IAM, Lambda, and related services
• Ensure appropriate security configurations, access controls, and cost monitoring are in place
• Support the deployment of new cloud-based components as the business evolves

• Serve as a primary escalation point for platform and integration issues raised by internal teams
