Job Description
Summary We are a marketplace. Sellers list there items onto our website, and buyers purchase. (Think like ebay). We don’t hold any stock. We have created an API for sellers to connect there stores to our site. Some sellers are on Shopify. We’re hiring a Shopify app developer to build a Phase-1 connector that lets Shopify sellers sync their products + variants + inventory into our website, and keeps Shopify stock aligned when items sells on our website. This is not a Shopify theme/storefront role. It’s an Admin API + inventory integration role. Phase 1 Scope (intentionally limited) -Shopify → marketplace -Import products + variants (each Shopify variant becomes a separate IFND listing) -Sync inventory levels from Shopify to marketplace(initial + ongoing) -marketplace → Shopify -marketplace sends a listing.sold webhook to the connector -Connector decrements Shopify inventory (delta-based, location-aware) Out of scope in Phase 1 -No order creation in Shopify -No full Order API -No refunds/cancellations sync -Sellers manage all order details inside IFND Shopify Constraints (important) -We do not have server access to seller stores (we can’t “install code” on their servers) -The connector must be a Shopify app that sellers install -Shopify image URLs are fine only if publicly accessible -Need to respect Shopify rate limits and handle retries -Must work for stores with 1,000+ products (and ideally 10k+ variants) What you’ll build -A Shopify app (public or custom app approach — you propose the simplest reliable option) -Backend service that: -runs initial import (Bulk Operations preferred for large stores) -maintains mapping (Shopify variant_id ↔ listing_id) -receives listing.sold webhook and updates Shopify inventory safely -handles idempotency (webhooks can be delivered more than once) -retries/backoff + basic logging Key design requirement: no duplicates on re-sync, no double-decrement on webhook retries. Deliverables -Working connector for 1 pilot Shopify store -Setup/install flow for additional sellers -Simple admin/config approach (even if minimal) -Short handover doc: how to deploy, configure, and support Required Experience -Built Shopify apps that use Admin API (GraphQL) in production -Inventory experience: InventoryItem / InventoryLevel / Locations -Webhooks + idempotency + retry queues -Bulk Operations API experience for large catalogs is a big plus Apply tot his job
