Senior Frontend Engineer — Plus Storefronts & Migrations

Shopify Inc.; United States; Remote; CAD 110,000 - 160,000; Full time

Job summary

Shopify Inc. is seeking a Senior Frontend Engineer for Professional Services to design and deliver native Shopify Plus storefronts for high‑volume brands.

You’ll lead technical discovery, implement solutions, and ensure scalable, robust experiences across themes, checkout, and extensions. You’ll collaborate with Solution Engineering, Customer Success, Engineering and Product on billable engagements, shaping scope, expectations, and outcomes while advancing merchant performance and developer

Qualifications

• Hands-on Shopify Plus development for high‑volume or enterprise merchants.
• Deep expertise in Shopify Themes and Liquid, including Online Store 2.0 architecture, content schemas, and theme settings.
• 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.

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
