Hire senior Shopify developers for themes, apps and Hydrogen
Senior Shopify engineers who build Online Store 2.0 themes, custom apps, checkout extensions and headless Hydrogen storefronts, on US hours.
By the Ryz Labs team · Updated October 2026
Hiring Shopify developers through Ryz gets you senior engineers who know the platform's limits and extension points, so your store stays fast and upgradable. They are in the top 1% of the engineers we interview, they join your ecommerce team, and they work within an hour of US time zones.
What our Shopify developers work on
Shopify work spans themes, apps, integrations and headless builds. Our engineers use Liquid, Online Store 2.0 sections and blocks, Shopify CLI, the Admin and Storefront GraphQL APIs, Shopify Functions, Checkout UI Extensions, Polaris, Remix-based app templates and Hydrogen with Oxygen hosting. Common work:
- Custom Online Store 2.0 themes with flexible sections so merchandisers can build pages without developer help.
- Private and public Shopify apps built on the Remix template, with webhooks, billing and admin UI extensions.
- Checkout customization with Checkout UI Extensions and Shopify Functions for discounts, delivery and payment rules.
- Headless storefronts with Hydrogen or Next.js on the Storefront API, for brands that need full control of the front end.
- Integrations with ERP, inventory, fulfillment and marketing systems through APIs and webhooks.
- Migrations to Shopify or Shopify Plus from other platforms, including product data, customers, orders and redirects.
Skills we vet for
- Liquid and theme architecture. Sections, blocks, app blocks, metafields and metaobjects, and keeping themes maintainable across updates.
- Shopify APIs. GraphQL Admin and Storefront APIs, cost-based rate limits, bulk operations and pagination.
- Extensibility. Shopify Functions in Rust or JavaScript, checkout and customer account extensions, and theme app extensions.
- App development. OAuth installs, session tokens, webhooks with verification, and the app billing API.
- Headless commerce. Hydrogen, Remix loaders, caching strategies on Oxygen, and cart and customer flows.
- Performance. Core Web Vitals on product and collection pages, image handling, script loading, and app bloat audits.
- Markets and B2B. Shopify Markets for multi-currency and multi-language stores, and B2B catalogs and price lists on Plus.
- Testing and deployment. Theme versioning with GitHub integration, preview themes, and safe releases during sales events.
How we vet Shopify developers
Recruiters look for Shopify engineers who have built custom themes, apps and integrations for live stores, not only installed apps and adjusted settings. ARC, our in-house ranking system, orders the pipeline. Candidates complete a structured NTRVSTA AI interview on Liquid, the Shopify APIs and commerce logic. Recruiters review each candidate before and after the interview and send you a curated shortlist. AI scores are advisory, and people make the decisions.
Sample interview topics
- A product page loads slowly and the theme includes scripts from twelve apps. How do you measure the impact of each and decide what to remove?
- Marketing wants a "buy two, get the third at half price" rule only for certain customer tags. How would you build it with Shopify Functions?
- You need to sync inventory for 100,000 variants every hour. How do you handle rate limits, bulk operations and partial failures?
- When does a Hydrogen headless build make sense over a well-built Liquid theme, and what does the brand give up?
- How do you verify Shopify webhooks, handle duplicates and keep an app's data consistent if webhooks arrive out of order?
Ways to hire Shopify developers
| Option | Best for | Trade-offs |
|---|
| Freelance marketplace | Theme tweaks and quick app setup | Many profiles are theme customizers. Custom app and checkout work needs deeper skills. |
| Staffing or recruiting agency | General ecommerce hiring | Shopify depth is hard to screen for. Liquid and app development often get lumped together. |
| In-house recruiting | A long-term ecommerce engineering lead | Senior Shopify engineers often work at agencies, so direct hiring can be slow. |
| Ryz Labs staff augmentation | Adding senior Shopify engineers to your ecommerce or digital team | You set priorities with merchandising and marketing. Best with an active store and backlog. |
| Ryz Labs dedicated team | A replatform, headless build or custom app delivered by one team | A tech lead plus engineers and design as needed, scoped together with a plan. |
Ryz is not the right fit if you want to book a freelancer for a few hours through a marketplace, or if you need engineers in European or Asian time zones. If you want engineers on your own payroll, an employer-of-record partner is the better option.
Why hire Shopify developers from Latin America
Ecommerce has grown fast across Latin America, and many senior Shopify engineers there have built stores and apps for US direct-to-consumer brands through agencies. They know the seasonal pressure of product drops and holiday sales, and how to prepare a store for traffic spikes.
Ecommerce teams make dozens of quick decisions every day: a promotion changes, a collection needs a new filter, an app conflicts with the theme. Our Shopify developers work within an hour of US time zones, so they can respond during your trading hours and watch a launch with you. They work in English and use your tools.
