Lead Shopify Software Engineer

Responsibilities

• Spearhead the build-out of custom Shopify Plus solutions, including headless storefronts (Hydrogen and Remix), custom middleware apps, and Liquid-based Online Store 2.0 themes where appropriate
• Create and ship custom platform extensions using Shopify Functions, Checkout UI Extensions, Customer Account UI Extensions, and Shopify Admin extensions
• Build solid backend services, webhook consumers, and data sync pipelines that connect Shopify with third-party enterprise systems (ERP, PIM, OMS, CRM)
• Work alongside the Shopify Solution Architect to translate high-level system designs into concrete engineering tasks, technical specs, and sprint deliverables
• Set and enforce engineering standards, covering thorough PR/code reviews, automated testing (unit, integration, E2E), and CI/CD pipelines (e.g., GitHub Actions, Shopify CLI workflows)
• Push forward storefront and API performance improvements, handling edge caching strategies on Shopify Oxygen, optimizing GraphQL query costs, and keeping Core Web Vitals green
• Advocate for AI-native development workflows across the team (e.g., Claude Code, Cursor, GitHub Copilot) to speed up feature delivery, scaffolding, and complex refactoring
• Define codebase-level context rules, custom prompts, and project guidelines so AI-generated code stays within Shopify API boundaries, TypeScript standards, and architectural patterns
• Use AI tooling to automate unit/E2E test generation, GraphQL schema validation, PR pre-reviews, and living technical documentation
• Apply strict quality, security, and verification guardrails to AI-assisted code generation to avoid hallucinations, performance regressions, or security vulnerabilities
