--- title: "Hiring Shopify Plus Developers in 2026" source: https://refact.co/insights/ecommerce/shopify-plus-developers author: "Saeedreza Abbaspour" date: "2026-08-29" --- # Hiring Shopify Plus Developers in 2026 A public company spent roughly six months and approximately one million dollars developing a single Shopify store with finance back-end integration. Another team placed nine mostly senior engineers on a single shop migration and took almost a year to do it. Neither of these projects was doomed because of Shopify. Both of these projects failed because of the way the work was scoped and staffed. That is the hiring problem for Shopify Plus developers in 2026: not if the candidate can push a theme edit, but if they will burn a year of runway before you get your first conversion. This article is for the operators and engineering managers who want to hire well in spite of the platform that is moving underneath them. Scripts will be replaced. Checkout.liquid will also be replaced. Agentic commerce will likely show up in the roadmap. Brief a generalist on last year’s playbook, and you will have to pay for a migration of features that you did not request. The right hire comes from knowing what to look for and what to pay for and also knowing what to avoid. ## What Actually Changed on Shopify Plus in 2026 There are three main shifts to note in hiring for this year. **Scripts to Functions.** Shopify Scripts, the Plus-only customization system based on Ruby, will be replaced by Shopify Functions. Functions run at the edge and therefore scale better than Scripts. There will now be a visual and no-code tooling layer. Discount logic, shipping rules, payment rules, and validation rules will all move here. If you are tasked with looking after a store built on Scripts, someone will need to rewrite that logic before Shopify disables the code. **Checkout.liquid and checkout extensibility.** Legacy checkout customization relied on Liquid templates that would break after each Shopify upgrade. Checkout extensibility features UI elements and APIs that allow partners to control their checkout interface, and are designed to be resilient to future platform updates. This is one of the biggest updates for Plus stores that have been able to control their checkout, and it is often one of the largest sources of “quiet” bugs that show up after launch when the migration is rushed. **AI and agentic commerce.** Shopify has begun to develop infrastructure for AI agents that conduct checkout on behalf of shoppers: a first-party MCP server, Universal Commerce Protocol, agentic plans, and the Catalog surface. Transactions no longer occur solely in the storefront. The quality and structure of product data and content combined with clean and functional APIs will serve as a greater differentiator than yet another homepage animation. Someone in your team who cannot verbalize these trends will not suffice for what you will need for a Plus store in 2026. This is not a vocabulary test, but rather a reflection of the work that lies ahead. ![Shopify Functions configuration screen in the Plus admin](https://cdn.refact.co/uploads/2026/08/image_placeholder_1-128.avif) Shopify’s discount configuration, shown here selecting various types, exemplifies how Functions now enable sophisticated, custom logic, replacing older developer customization models. · Source: genovawebart.com ## The Skills That Separate Plus Developers From Shopify Generalists There are many developers with the ability to create a Shopify store. There are even fewer people who can create a Plus store that can stand the pressures of its own success. ### Deep Liquid, but also Functions and extensibility Liquid is the templating language utilized by almost all storefronts. To provide the functionality that OS 2.0 sections, metafields, and theme blocks provide, Plus developers need to know Liquid cold. Extending Liquid beyond these use cases and knowing how to work with Functions, built either in JavaScript or Rust, and how the checkout UI is built and how to deal with the app configuration surface for customer-facing extensions is also useful. Developers who only know Liquid will struggle the first time you need custom discount logic that used to live in Scripts. ### Integration architecture, not just app installs Most Plus stores connect to an ERP, an ecosystem of CRMs, subscriptions, fulfillment services, and tax engines, as well as a couple of business intelligence tools. Each of these connectors introduces new state that needs to be reconciled with Shopify. Candidates should be able to explain how they deal with webhooks that fail and how they deal with partial refunds against an applied discount, and how they detect drift between Shopify and the ERP. If they say they use an app, you should continue your search. Coupons in combination with partial returns are one of the most common reasons why projects miss their timelines during a migration. ### Performance measured where it matters Time to Interactive is the e-commerce conversion metric, not Lighthouse scores taken at 3 am on an empty cart. How do developers profile a product page and how do they ensure that third-party tags are not broken, and how do they audit apps prior to installation? Our [Shopify theme development](https://refact.co/insights/ecommerce/shopify-theme-development) guide goes into more detail regarding operational budgets in practice. ### B2B and multi-store fluency If your store sells to wholesalers, runs multiple regional stores, or uses company-level pricing, the candidate must understand B2B catalogs, company location objects, and how markets interact with checkout. Generalists often make things up, and three months later there are broken price lists. ### Headless judgment, not headless enthusiasm Hydrogen and Oxygen are real, but headless isn’t always the answer when dealing with Plus stores. A candidate should be able to identify when Liquid is the appropriate choice, or when it isn’t, and they should be honest when they say traditional Liquid storefronts clear Core Web Vitals more often than headless. We covered this tradeoff in our article on [Shopify headless commerce](https://refact.co/insights/ecommerce/shopify-headless-commerce). ## How to Interview for the Work That Actually Breaks Stores Most Shopify Plus interviews are focused on what a candidate can build. The more important question is how they act when something breaks without any warning. One developer described a situation where the client was happy on day 21, but then payment webhooks started failing, order confirmation emails stopped going out, and the admin was crashing in Safari. The build worked in the demo, but it failed in production. Interview for that gap. Some good interview questions: - Walk through the last time a Shopify update broke something you shipped. What was the root cause? - How do you test checkout across payment methods, shipping zones, and browsers before launch? - You need to move a store from checkout.liquid to checkout extensibility. What is the sequence? - Describe how you would migrate a Scripts-based tiered discount to Functions. What breaks if you get it wrong? - The client wants a 60-day rebuild. The catalog has 40,000 SKUs, three custom apps, and a NetSuite integration. What do you push back on? The best answers are always specific, and typically make candidates uncomfortable. A candidate who has never argued against a bad timeline has probably never delivered a real project under a constrained timeline. ## The Migration Trap The most expensive failure mode for Plus is over-engineered migrations. They happen predictably. Months of Domain-Driven Design workshops precede the first access to the admin, and teams are dominated by senior engineers who discuss architectures and edge cases, like vouchers and partial refunds, which no one bothers to model until they are released to production. This leads to the dreaded six-month, seven-figure single store build. The opposite approach is more boring. However, it leads to better outcomes. A small team builds a production-like data staging environment on day one. A cutover plan occurs before the theme is selected. A redirect map is built and treated as a first-class deliverable. Data validation between Shopify and the ERP occurs on a weekly basis. For the full sequence, refer to our [Shopify migration checklist](https://refact.co/insights/ecommerce/shopify-migration-checklist) and [migration services playbook](https://refact.co/insights/ecommerce/shopify-migration-services). The executive summary: The more excited a team gets about the whiteboard before a redirect map is built, the more that team needs to be replaced. ![Migration planning whiteboard for a Shopify Plus replatform](https://cdn.refact.co/uploads/2026/08/image_placeholder_2-124.avif) A meticulously planned project timeline, detailing every step from requirements to launch and beyond, illustrates how thorough preparation prevents migration pitfalls. · Source: boardmix.com ## Freelancer, Agency, or Product Partner The right shape of engagement depends on the operating model behind the store, not the size of the catalog. **A freelancer** is the right choice when the scope is narrow and the rest of the store is otherwise stable: a specific Functions migration, a checkout extension for one payment method, a performance pass on a product template. The risk is discontinuity. If the freelancer leaves mid-project, everything they know about it leaves with them. **An agency** is what we recommend for a replatform, a headless build, or a launch with significant operational risk. The tradeoff is process weight. Enterprise agencies tend to add governance and project scoping with more predictable timelines, though their per-hour rate does not dictate the total project cost. We recommend a long-term product partner when the store is a system that is constantly evolving: more markets, more customer segments, and ongoing integrations. Refact typically works this way, with client relationships spanning on average two years. The economics are quite different from a project-based agency as the focus is on what the store will look like in 18 months versus what is the next sprint to be shipped. This is what we describe on our [Shopify development services page](https://refact.co/services/shopify). If you are still deciding whether you need a partner at all, our ecommerce development company [page](https://refact.co/insights/ecommerce/ecommerce-development-company) covers the questions that help you determine real capability versus a good pitch deck. ## What This Looks Like in Practice When we worked on [Broya’s Shopify store](https://refact.co/work/broya-living/), the interesting work wasn’t a new theme. The store already had decent traffic. The work was transforming the store from browsing to checkout. This involved improving each product and collection page to describe the product, as well as creating a subscription model in the cart. Conversions have continued to climb after the work was completed, and the reason is simple. The work focused on how the business sells, not on the redesign. [Fiore Designs](https://refact.co/work/fiore-designs/) was the polar opposite. The storefront worked fine, but Shopify’s stock checkout couldn’t model the complexities of running a same-day flower delivery business. Zip-code-based delivery zone checks, time-window selection, and zone-based pricing are examples of work that used to reside in Scripts, and now live in Functions and checkout extensions. A generalist would most likely have installed three apps in a rushed manner. The right hire modeled the workflow and built the extension. ## What to Put in the Contract The contract is where founder time gets protected or burned. No matter whom you hire, specify: - Deliverables tied to acceptance criteria, not vague milestones. - Ownership of code, theme files, custom apps, and the Shopify Partners account access. - Environment access: development store, staging, production, and who can touch what. - Testing scope: browsers, devices, payment methods, and edge cases like partial refunds. - A migration rollback plan with the trigger conditions in writing. - Launch support window with response times, not just business hours. - Change request process and rate for out-of-scope work. - Post-launch responsibilities for a defined period, including monitoring. If any of that is blurred at signing, the confusion will persist at the review of the incident three months later. ## Budget Reality Plus development is priced based on risk and complexity, not by the hour. A straightforward Functions migration can run in the tens of thousands. A full replatform of an ERP, subscription, and B2B features can easily clear six figures and can run into seven figures if the scope is honest about the integration work needed. Our [Shopify website cost guide](https://refact.co/insights/ecommerce/shopify-website-cost) can help you with the ranges. There are two rules of thumb worth remembering. The first is that if a proposal appears to be significantly cheaper than other quotes, a big part of the proposed work has likely been omitted. The second is that post-launch retainers should be considered part of the total cost of the work and not an afterthought. The stores that remain fast, integrated, and converting are the ones where someone is still watching. ## What to Track After Launch After a store goes live, the important signals are boring: order accuracy against the ERP, the success of webhooks, conversion rate of the checkout for each device and browser, the Time to Interactive for each product page, regressions of accessibility, and the response time of support. If your Plus developer cannot show you these metrics in a work activity dashboard in the second week, you hired someone for delivery and not for ownership. ## The Short Version The best Shopify Plus developer of 2026 is not the one with the fastest scroll on their portfolio. It is the one who can speak to the Functions and extensibility of the checkout and the potential failure modes of integration without a script. This is the one who will push back on a six-month time frame for a task that should take three, and who will write the redirect mapping instructions prior to the design. If you are trying to finalize some key decisions that must occur before a Plus build or migration, the early definition of these key decisions is the cornerstone of Refact’s [Shopify development work](https://refact.co/services/shopify). Focus on the business problem. Hire the store around it. ## FAQ ### What is the difference between a Shopify developer and a Shopify Plus developer? A Plus developer works with features that only exist on Shopify's enterprise tier: Functions, checkout extensibility, B2B catalogs and company objects, multi-store markets, and higher API limits. A generalist Shopify developer can build a strong storefront but usually cannot design the integration, checkout, and B2B logic that Plus stores rely on. The gap shows up most on migrations and post-launch reliability. ### How long should a Shopify Plus migration take? For a mid-market store with a clean catalog and a few integrations, a well-run migration lands in the range of three to five months. Migrations that stretch to a year usually have too many senior engineers debating architecture and too little time in staging with production-like data. If a proposal front-loads workshops instead of a redirect map and a data reconciliation plan, expect the timeline to slip. ### Do I need to move off Shopify Scripts right now? Yes, if any part of your discounts, shipping, payments, or validations depends on Scripts. Shopify is retiring the system and Functions is the replacement. Rewriting logic in Functions is not a straight port. Tiered discounts and multi-condition cart rules often need to be modeled differently, so plan for real engineering time rather than a quick swap. ### Should I build headless on Shopify Plus? Only when the storefront requirements clearly justify it. Traditional Liquid storefronts clear Core Web Vitals more often than Hydrogen or other headless setups, and headless adds infrastructure, deployment, and hiring complexity. Headless makes sense when you need a shared frontend across multiple commerce backends, unusual UX patterns, or content workflows that Shopify's admin cannot support. ### How do I make sure my Shopify Plus store is discoverable to AI agents? Focus on clean, structured product data, complete metafields, and consistent taxonomy. Shopify's first-party MCP server and the Universal Commerce Protocol expect well-formed catalog data to expose products to agents like ChatGPT, Gemini, and Copilot. This is closer to disciplined content operations than to a marketing tactic, and it rewards the same work that helps search engines.
