Modern Checkout Customization: Take full ownership of migrating legacy scripts and designing advanced, secure checkout logic using Shopify Checkout Extensibility and Shopify Functions . System Integrations: Architect seamless API integrations between Shopify and enterprise-level external systems, including ERPs (SAP, NetSuite), CRMs, and complex PIM (Product Information Management) systems. Performance & CRO Infrastructure: Own Core Web Vitals, technical SEO health, and server-side optimization to ensure peak loading speeds during global high-traffic sales events (e.g., Black Friday). Technical Leadership & Governance: Establish clean code standards, lead comprehensive code reviews, manage CI/CD pipelines, and maintain technical documentation to ensure long-term system scalability. Requirements Experience: 6–10 years of professional experience in fullstack software engineering, with a strict, proven focus on enterprise-level Shopify / Ecommerce platforms .

Checkout Extensibility: Proven, hands-on experience implementing Checkout Extensibility and writing custom business logic via Shopify Functions .
