About APIWORX

APIWORX runs the multi-enterprise automation layer for high-volume commerce and ERP operations. We move millions of orders, inventory updates, and EDI documents every month between Shopify, BigCommerce, Amazon, NetSuite, Sage Intacct, Acumatica, Business Central, and 400+ other systems — through our Data APIXX intelligent data layer.

What you''ll do

Design and build production integrations between commerce platforms (Shopify, BigCommerce, Amazon, Wayfair) and ERPs (NetSuite, Sage Intacct, Acumatica, Business Central, Sage X3).
Own connector lifecycle: API discovery, schema mapping, authentication (OAuth2, API keys, mTLS), pagination, rate-limit handling, retries, and idempotency.
Build event-driven flows on top of webhooks and queues that survive partner outages without losing transactions.
Contribute to the Data APIXX unified data layer — normalize disparate schemas into a clean, queryable model.
Diagnose live customer issues: trace webhook payloads, replay failed jobs, fix data drift, and ship the durable fix.

Requirements

5+ years building production integrations or backend services.
Strong TypeScript / Node.js (or comparable: Python, Go) and PostgreSQL.
Deep practical knowledge of REST and GraphQL APIs, OAuth2, webhooks, and queue-based architectures (SQS, pgmq, RabbitMQ, Kafka).
Experience with at least one major ERP or commerce API (NetSuite SuiteTalk/SuiteScript, Sage Intacct API, Shopify Admin API, Amazon SP-API, BigCommerce, Acumatica).
Comfort with EDI (X12 850/810/856/940/945) is a strong plus.
You write tests, you read logs, you ship.

Nice to have

Background in 3PL, retail, or B2B distribution operations.
Experience with serverless edge runtimes (Supabase, Cloudflare Workers, Deno Deploy).
Open-source contributions to integration tooling.
