Role Overview

We are looking for a Senior Shopify Full-Stack Developer to take ownership of the technical development and infrastructure behind our DTC e-commerce storefronts.

This is a hands-on engineering role for someone who can work across the Shopify storefront, backend systems, custom applications, integrations, automations, and third-party commerce infrastructure.

Key Responsibilities

• Own the development and technical maintenance of Shopify-based DTC storefronts and supporting systems.
• Build and maintain custom Shopify themes and storefront functionality using Liquid, JavaScript/TypeScript, React, and Shopify APIs.
• Develop custom Shopify applications, middleware, services, and integrations when native Shopify functionality is insufficient.
• Determine when to use Shopify Flow, Shopify Functions, custom apps, APIs, webhooks, or external middleware to solve a business or technical problem.
• 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.
• Experience working with 3PLs, warehouses, fulfillment systems, inventory synchronization, or other commerce operations infrastructure.
• Experience with Shopify migrations, multi-warehouse environments, or complex order/fulfillment integrations is highly valuable.
• Strong backend development experience using Node.js or another comparable backend technology.
• Experience working with databases and backend data management.
• Strong understanding of REST and GraphQL APIs, authentication, webhooks, asynchronous processes, and data synchronization.
• Experience with subscription commerce and platforms such as Skio or Recharge.
