The role

You will be our lead Shopify engineer. You take a client's store from requirements to launch and support: custom themes, private and custom apps, point-of-sale setups and integrations with the systems the business already runs. You will also review the work of junior developers and interns and set the standard for how we build on Shopify.

What you'll work on

  • Building and customising themes with Liquid and Online Store 2.0 (sections, blocks, metafields and metaobjects)
  • Writing custom code where apps fall short: theme JavaScript, Liquid logic, checkout and cart customisations
  • Building custom and private apps with the Shopify Admin and Storefront APIs (GraphQL and REST), webhooks and App Bridge
  • Setting up and integrating Shopify POS: POS UI extensions, hardware, staff and location setup, and keeping online and in-store inventory, orders and customers in sync
  • Integrating Shopify with ERPs, inventory and accounting tools, payment gateways, shipping and courier services, marketplaces and CRMs
  • Checkout Extensibility and Shopify Functions for discounts, delivery and payment rules
  • Store migrations (from WooCommerce, Magento and others), speed optimisation, Core Web Vitals and technical SEO
  • Shopify Flow and automation, Shopify Plus features and multi-market or multi-currency stores
  • Debugging and fixing live stores carefully, without downtime

What you need

  • 5+ years of hands-on Shopify development, with live stores you can show us
  • Strong Liquid, JavaScript, HTML and CSS; working knowledge of Node.js or a similar back-end
  • Real experience with Shopify POS setups and POS integrations
  • Experience with the Shopify Admin and Storefront GraphQL APIs, webhooks and app development
  • Experience integrating third-party systems (ERP, inventory, payments, shipping)
  • Git, theme CLI and a clean development workflow (development stores, theme previews, safe publishing)
  • Clear written English for working with clients and the team

Nice to have

  • Shopify Plus and Checkout Extensibility projects
  • Hydrogen or headless storefronts
  • Published apps or theme work on the Shopify App Store or Theme Store
  • Experience mentoring junior developers

Working arrangements

  • Type: Full-time
  • Location: Remote (India)
  • Hours: regular working hours with overlap for client calls

Salary

₹30,000–₹50,000/month, based on your experience, the depth of your Shopify work and how you do in the technical review.
