Senior Shopify Developer, Professional Services

At Shopify, we're making commerce better for everyone — from independent entrepreneurs to global brands. We provide the scalability, reliability, and flexibility merchants need to build, grow, and evolve their businesses. Shopify powers commerce for brands like Allbirds, Gymshark, and Staples. Our Professional Services team works with those brands directly, on paid engagements, to architect and deliver native Shopify experiences that move real numbers: conversion, performance, and developer velocity. This is where Senior Shopify Developers come in. Some of our merchants are migrating to Shopify Plus from legacy enterprise platforms — untangling years of custom logic, integrations, and multi-market complexity. Others are already on Plus and need their storefront rebuilt to perform at a different scale. You'll build for both. A typical engagement might mean replatforming a global brand across a dozen markets without losing a point of conversion, migrating a merchant off legacy Scripts onto Checkout Extensibility ahead of peak season, or standing up a B2B storefront alongside an existing DTC build. You'll work alongside Solution Engineering, Customer Success, Engineering and Product — and because these are billable engagements, you'll help scope the work, set expectations, and own the outcome. What you can expect Engagements ranging from short technical spikes to 6 month builds A genuinely hands-on role — you'll be writing code, not just reviewing other people's A fast-moving environment where requirements shift and ambiguity is normal Autonomy to solve complex problems creatively, with mentorship and room to grow from each engagement Direct influence on merchant outcomes and on Shopify's roadmap Key Responsibilities Build and ship native Shopify Plus storefronts — leading technical discovery, solution design, and hands-on implementation across themes, checkout, and app/extension surfaces Own migrations for merchants coming from legacy platforms: assess the existing architecture, define the target state on Plus, and sequence the work so nothing breaks in flight Work at Plus scale — expansion stores, multi-market and multi-currency setups, B2B alongside DTC, high-traffic launches, and the operational surfaces Plus merchants actually run on (Flow, custom apps, Launchpad) Set the performance bar. Define frontend standards (Core Web Vitals, rendering strategy, asset discipline) and coach merchant and partner teams to hit them Make the hard build calls and explain them — Liquid vs. Hydrogen/Oxygen, native vs. app, Checkout Extensibility patterns, and content modeling with metafields and metaobjects Scale your impact beyond the engagement by building reusable reference implementations, accelerators, and internal tooling — Theme App Extensions, Checkout UI Extensions, Functions — so the next team starts further ahead Work across the org with Solution and Enterprise Architects, Merchant Success, Product, and Engineering to unblock complexity, surface risk early, and feed what you learn back into the product roadmap Communicate with range — deep technical detail with engineers, clear recommendations and tradeoffs with executive stakeholders Qualifications Significant hands-on Shopify Plus development experience, shipping production work for high-volume or enterprise merchants Deep expertise in Shopify Themes and Liquid, including Online Store 2.0 architecture, content schemas, and theme settings Strong modern frontend fundamentals: storefront JavaScript, component architecture, advanced CSS, and demonstrable performance optimization work Hands-on experience across Shopify's Plus extensibility surfaces — Checkout UI Extensions, Theme App Extensions, Functions, App Bridge — including migration patterns off legacy Scripts Experience with Plus-specific complexity: expansion stores, Shopify Markets and multi-region setups, B2B, and custom app development Strong GraphQL and REST proficiency across the Admin and Storefront APIs, with webhooks and rate-limit-aware patterns Content modeling with metafields and metaobjects Fluency with Shopify CLI, Git-based workflows, and automated checks (Theme Check, ESLint/TypeScript) Demonstrated use of AI tools (Cursor, Copilot, Claude) to ship production code and build internal tooling that speeds up delivery Excellent communication with both engineering and executive audiences, and a track record of turning ambiguous merchant goals into clear builds with measurable outcomes Nice to have Hydrogen/Oxygen experience, with a clear point of view on when headless is actually the right call Experience replatforming merchants onto Plus from Magento/Adobe, Salesforce Commerce Cloud, commercetools, or similar Subscriptions and Bundles implementations on Plus Agency, consultancy, or SI background delivering for enterprise merchants Familiarity with ERP/OMS/PIM integrations via Admin APIs and webhooks Public thought leadership — talks, writing, podcasts We're interested in what you can do.
