React Performance Engineer @ Shopify

Shopify's storefront platform serves millions of storefronts worldwide. We need a React Performance Engineer to identify and fix rendering bottlenecks, reduce bundle sizes, and improve Core Web Vitals across our React-based storefront components. You'll write benchmarks, use profiling tools, and mentor other engineers on performance best practices. Experience with React DevTools Profiler, Lighthouse, and bundle analyzers is required. Familiarity with Hydrogen (our React-based commerce framework) is a bonus.
