Senior Frontend Engineer, Professional Services

Senior Frontend Engineer, Professional Services 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.

Engagements ranging from short technical spikes to 6 month builds

A genuinely hands‑on role — you'll be writing code, not just reviewing other people's

A fast-moving environment where requirements shift and ambiguity is normal

Autonomy to solve complex problems creatively, with mentorship and room to grow from each engagement

Direct influence on merchant outcomes and on Shopify's roadmap

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

Content modeling with metafields and metaobjects
