JOB OVERVIEW

We are looking for an experienced Shopify app developer to build a Shopify app that connects Shopify stores to our SaaS platform.

The core functionality is simple: when a customer places an order, the required order/customer information needs to be sent securely to our API.

Our existing senior developer will build and manage everything on our SaaS/backend side.

You will not receive access to our backend, servers or source code.

What we need:

- Shopify app installation/authentication
- Secure connection between the Shopify store and our API
- Capture relevant order events
- Send required order/customer information to our API
- Handle app uninstall/reconnection
- Basic error handling/logging
- Prepare the app properly for Shopify App Store submission
- Assist with any technical changes required during Shopify review

Requirements

You should have real experience with:

- Shopify app development
- Shopify Admin API / GraphQL
- OAuth
- Shopify webhooks
- Shopify App Store requirements
- External REST/API integrations

Please include:

1. Links or examples of Shopify apps you have built
2. Whether any of your apps are currently in the Shopify App Store
3. Your hourly rate
4. Your estimate of the number of hours required

Expected outcome: a polished public Shopify app.

Budget guideline: USD $6–$10/hour, depending on experience.

We are particularly interested in someone we can continue working with as the app develops. We also have another app that is more complex and needs it's own Shopify app as well.
