Shopify Developer (Backend-Focused / Custom Apps, Integrations)

About the Project

We are supporting a long-term client with a strong background in React and Node.js development, working with major telecom companies such as AT&T, Vodafone, and Telos International.

This engagement marks a new direction for the client: their first Shopify-based project.

The end customer operates in the mobile device diagnostics industry, providing a proprietary system that combines hardware (USB diagnostic hubs) and software to automatically assess the condition of mobile devices (battery health, memory, display, etc.) when plugged in.

Their solution allows retailers and telecom operators to instantly evaluate returned phones without sending them to repair centers, significantly reducing logistics costs and turnaround times.

The company originally started in the law enforcement sector, building tools for mobile data extraction during investigations, before pivoting into commercial telecom and retail diagnostics.

Project Overview

• Existing Shopify store already exists for mobile devices, but the new project is expected to be a significant rebuild or extension rather than a simple theme update
• Strong focus on backend-heavy Shopify development
• Work will include:
  • Custom Shopify app development
  • API integrations between Shopify and external systems
  • Logistics and warehouse workflow automation
  • Connection between Shopify storefront and proprietary diagnostic backend platform
• Scope is expected to go beyond standard Shopify theme customization

Estimated duration: 2–5 months, suggesting substantial custom development work

Technical Focus

We are specifically looking for a Shopify Developer with strong backend capabilities, including:

• Shopify Apps (custom/private apps)
• Shopify Admin API / Storefront API
• Node.js backend development
• API design & integrations
• Experience with warehouse/logistics or ERP-style systems (strong plus)
• Ability to work on system architecture beyond frontend theming

Important Context

• This is the first Shopify project for the client’s team
• Long-standing relationship with the client (8+ years), with high trust
• Requirements are still evolving and will be clarified after the next client meeting
• Candidate should be comfortable working in an environment with some ambiguity at the start

Communication & Work Style

• Client expects very clear, structured, and concise communication
• High availability is required (this is a strict expectation, not a preference)
• Both part-time and full-time engagement possible, to be finalized after initial discussions

Compensation

• Starting at approximately $20/hour
• Budget flexibility up to $26–28/hour for highly relevant Shopify backend experience

Ideal Candidate

You are a strong fit if you:

• Have solid Shopify backend / app development experience
• Are comfortable building integrations between Shopify and external systems
• Think in APIs, workflows, and system architecture rather than only themes/UI
• Can work independently in an initially unclear scope
• Communicate clearly and reliably in a fast-moving client environment
