Senior Frontend Engineer, Professional Services (Americas)

About The Role At Shopify, we're making commerce better for everyone — from independent entrepreneurs to global brands. We provide the scalability, reliability, and flexibility merchants need to build, grow, and evolve their businesses. Shopify powers commerce for brands like Allbirds, Gymshark, and Staples. Our Professional Services team works with those brands directly, on paid engagements, to architect and deliver native Shopify experiences that move real numbers: conversion, performance, and developer velocity. This is where Frontend Engineers come in. Some of our merchants are migrating to Shopify Plus from legacy enterprise platforms — untangling years of custom logic, integrations, and multi-market complexity. Others are already on Plus and need their storefront rebuilt to perform at a different scale. You'll build for both. A typical engagement might mean replatforming a global brand across a dozen markets without losing a point of conversion, migrating a merchant off legacy Scripts onto Checkout Extensibility ahead of peak season, or standing up a B2B storefront alongside an existing DTC build. You'll work alongside Solution Engineering, Customer Success, Engineering and Product — and because these are billable engagements, you'll help scope the work, set expectations, and own the outcome. What you can expect Engagements ranging from short technical spikes to 6 month buildsA genuinely hands-on role — you'll be writing code, not just reviewing other people'sA fast-moving environment where requirements shift and ambiguity is normalAutonomy to solve complex problems creatively, with mentorship and room to grow from each engagementDirect influence on merchant outcomes and on Shopify's roadmap Key Responsibilities Build and ship native Shopify Plus storefronts — leading technical discovery, solution design, and hands-on implementation across themes, checkout, and app/extension surfacesOwn 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 flightWork 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.
