Build and maintain integrations between Shopify and third-party systems, including 3PLs, warehouses, subscription platforms, CRM/marketing platforms, product/review platforms, and other commerce tools. Develop and maintain backend services and data flows supporting Shopify operations. Work on 3PL migrations, multi-warehouse setups, fulfillment workflows, inventory synchronization, and order/data integrations. Troubleshoot and resolve issues involving orders, products, variants, inventory, subscriptions, fulfillment, integrations, APIs, and data synchronization. Build and maintain subscription functionality and integrations using platforms such as Skio or Recharge. Develop automations and workflows that reduce manual operational work and improve reliability. Work with Shopify APIs, GraphQL/REST APIs, webhooks, authentication, and asynchronous processes. Build and maintain custom functionality across Shopify's backend and storefront architecture. Develop responsive, high-performance storefront experiences using Liquid, React, and/or Hydrogen. Optimize page speed, Core Web Vitals, mobile performance, and storefront reliability. Implement and maintain CRO and A/B testing, including experiments using tools such as Intelligems, Convert, or VWO. Integrate and maintain marketing and customer-data platforms such as Klaviyo and Okendo where required. Investigate production issues independently, identify root causes, and implement durable fixes. Use AI-powered development tools to accelerate development while independently validating and testing generated code. Write, test, review, and deploy production code following strong engineering practices. Maintain Git/GitHub workflows, including branches, pull requests, testing, and code reviews. Own technical decisions from implementation through production without relying on another engineering team for escalation. Requirements 7+ years of professional software development experience, with significant hands-on Shopify experience. Deep experience building and maintaining production Shopify stores and custom Shopify functionality. Strong experience with Shopify Liquid, JavaScript/TypeScript, Shopify APIs, and webhooks. Hands-on experience with Shopify Flow, Shopify Functions, custom Shopify apps, or Shopify middleware. Experience building integrations between Shopify and external systems using APIs, webhooks, and custom services.
