Full Stack Developer — AMC

We are looking for an experienced Full Stack Developer on AMC to take technical ownership of our live e-commerce website and its underlying integrations. The website is built on a headless Shopify architecture, with a custom Next.js frontend and Shopify functioning as the commerce backend. The system integrates with multiple third-party services for payments, authentication, order management, logistics, communication and analytics. This is therefore not a standard Shopify theme maintenance role. The developer will be responsible for maintaining, troubleshooting, monitoring and improving the existing system and ensuring that critical customer and order journeys remain functional.

New features, major architectural changes or substantial development work can be handled separately depending on scope. Before you apply Please apply only if you are comfortable taking ownership of an existing production e-commerce application with multiple interconnected APIs and third-party services. You should be comfortable entering an existing codebase, understanding its architecture and independently troubleshooting production issues. Experience with Shopify alone is not sufficient.
