You will own the integrations between commerce platforms (Shopify, POS, OMS, third-party SaaS) and the data that moves through them for a large replatforming program. The standard is data correctness at the systems-of-record level: orders, inventory and fulfillment must agree across every platform, provably, before and after cutover. This is a long-term, full-time engagement. It is backend integration engineering, not storefront or theme work.

Key Responsibilities:

• Build and maintain REST and GraphQL integrations with Shopify, POS, OMS and third-party business applications

• Implement OAuth flows, webhook verification and processing, retries, deduplication and error handling for production data flows

• Handle the realities of distributed data: duplicate events, out-of-order delivery, partial failures, eventual consistency

• Develop new API integrations with enterprise and SaaS platforms as the program expands

• Own SQL and BigQuery work wherever integrations require data movement or transformation

• Build automated reconciliation checks so systems of record stay in agreement

• Troubleshoot production integrations and data quality issues end to end

Requirements:

• 5+ years of backend engineering focused on API integrations between enterprise or SaaS platforms

• Strong Python in production

• REST and GraphQL integration experience on both consuming and building sides

• OAuth, API authentication, webhooks and robust error handling patterns

• Practical command of idempotency, deduplication and reconciliation design

• Strong SQL; hands-on data integration or ETL experience

• AWS deployment experience with Docker and CI/CD

• Fluent English

• Minimum 4 hours daily overlap with US Eastern time, full-time availability

Nice to Have:

• Google BigQuery

• Shopify APIs (Admin GraphQL, webhooks, Fulfillment Orders) or Salesforce Commerce Cloud

• POS, OMS, ERP or fulfillment system integration experience

• Event-driven integration patterns: queues, event buses, connectors
