Job summary

Shopify is seeking a Senior Shopify Developer to architect and deliver native Shopify Plus storefronts, leading technical discovery and hands-on implementation across themes, checkout, and app surfaces.

You will migrate merchants from legacy platforms to Plus, support multi-market setups, B2B, and collaborate with Solution, Enterprise Architects, Merchant Success, and Product to shape the roadmap.

Qualifications

• Significant hands-on Shopify Plus development experience shipping production work.
• Deep expertise in Shopify Themes and Liquid, including Online Store 2.0 architecture.
• Strong frontend fundamentals: JavaScript, CSS, and performance optimization.
• Hands-on experience across Shopify’s Plus extensibility surfaces — Checkout UI Extensions, Theme App Extensions, Functions, App Bridge.
• 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 to ship production code and build internal tooling.

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
• 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
• 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
