Shopify Backend Developer

Avnzor is a Saudi-based, app-first health, beauty, and wellness platform serving the modern GCC consumer. Inspired by the legacy of Ibn Zuhr (Avenzoar), Avnzor blends trust, authenticity, and technology to deliver premium products through a scalable digital ecosystem.

Our platform supports 60,000+ SKUs, high transaction volumes, and complex integrations across Shopify, custom backend systems, mobile applications, OMS, WMS, and multiple payment providers. As we scale aggressively in the Kingdom, Shopify sits at the core of our ecommerce architecture.

This is a full-time, on-site role located in Riyadh for a Shopify Backend Developer I at Avnzor.

This role is focused on scalable Shopify architecture, performance optimization, and complex system integration. You will be responsible for managing and strengthening Avnzor’s Shopify backend to support a large product catalog, advanced filtering logic, checkout optimization, and seamless integration with our custom backend and mobile app.

You will be responsible for:

• Managing and optimizing Shopify backend architecture
• Handling large product catalogs (60,000+ SKUs) with proper taxonomy and metafields
• Building and maintaining custom Shopify integrations (APIs, webhooks)
• Ensuring real-time inventory synchronization with backend and WMS
• Customizing checkout logic and improving conversion flows
• Optimizing site speed and performance
• Managing product collections, filters, and search functionality
• Integrating payment gateways and third-party apps
• Troubleshooting sync issues, product visibility issues, and checkout errors
• Supporting campaign launches and high-traffic spikes

This is not a theme-only role — this is a core ecommerce systems role responsible for performance, scalability, and conversion.

• Strong experience working with Shopify backend and Shopify APIs
• Deep understanding of Shopify Liquid, metafields, and custom product structures
• Experience with Shopify webhooks and third-party integrations
• Strong understanding of ecommerce inventory logic and order flow
• Experience optimizing Shopify performance and site speed
• Knowledge of checkout customization and conversion optimization
• Experience integrating payment gateways and logistics providers
• Strong debugging and system troubleshooting skills
• Experience working in high-growth ecommerce environments

We are looking for someone who understands that:

• 60,000+ SKUs require structured taxonomy and data discipline
• Slow page speed kills conversion
• Inventory sync failures create operational chaos
• Campaign spikes must not break the system

You should think in terms of scale, performance, integration reliability, and conversion optimization — not just Shopify configuration.
