Full Stack Developer - Sr. Shopify Hydrogen Developer

Full Stack Developer (Shopify/Hydrogen)
Location: Remote ( Philippines, Latin America or Eastern Europe)
Schedule: East Coast Time Zone (9-5 Full-Time)
Salary Range: USD Open based on experience

We are a US-based e-commerce retailer operating multiple storefronts. We run lean: operational efficiency matters more than scale. Our architecture is custom headless: Shopify Hydrogen (React Router) for storefronts, Algolia for search, Storyblok for CMS, and a mature Django monolith handling ERP/PIM/CRM functions.

We're not a "standard" Shopify setup. Management often expects "Shopify just does this"—but with our headless architecture, many things that "just work" in normal Shopify (feed syndication, native search, content management) require custom middleware, API integrations, or creative workarounds.

We're seeking a pragmatic Full Stack Developer to navigate this gap: someone who can either build the solution or knows when to escalate for architectural discussion.

Key Responsibilities

Hydrogen & Frontend Development

• Build and maintain fully custom Shopify Hydrogen storefronts using React Router, implementing complex commerce features and headless integrations
• Implement responsive UIs using HTML, CSS, and modern React; own frontend performance across all storefronts
• Manage migrations from legacy frontends (one Shopify Liquid, two Django-based) to Hydrogen with data integrity and minimal business disruption
• Debug and optimize the full data flow from React components through GraphQL to backend systems

Backend Integration & API Work

• Extend and maintain Python/Django code powering GraphQL API integrations between Shopify and our internal PIM/ERP/CRM monolith
• Build custom middleware and integrations when "standard" Shopify features don't work with our headless stack (e.g., custom feed generators for syndication, Algolia reindexing logic)
• Modify data exchange layers and API endpoints as business requirements evolve
• Navigate and enhance monolithic Django codebase without breaking existing functionality

Infrastructure & Deployment

• Manage software-defined infrastructure for Hydrogen deployments—build CI/CD pipelines, configure environments, and automate releases to Oxygen or similar edge platforms
• Own the deployment toolchain from local development through production
• Troubleshoot deployment and infrastructure issues across the stack

Translation & Problem-Solving

• Translate ambiguous business requests ("we need Pinterest syndication," "can we change how search works?") into technical approaches—assessing whether this is a quick tweak, custom integration, or architectural discussion
• Identify when requirements touch core architecture, involve significant data migration, or have business implications that need CTO input; escalate strategically rather than habitually
• Communicate technical constraints to non-technical stakeholders without being dismissive or overly technical

Requirements

Non-Negotiable Technical Requirements

• 3+ years of experience building custom eCommerce storefronts using  Shopify Hydrogen ,  React , and  React Router .
• Proven experience developing headless commerce solutions and implementing complex frontend functionality.
• Hands-on experience maintaining and extending  Python/Django applications .
• Deep understanding of  GraphQL APIs , REST integrations, and data synchronization between platforms such as Shopify, ERP, CRM, and PIM systems.
• Demonstrated success migrating legacy applications to modern architectures with minimal business disruption.
• Experience working with monolithic codebases and integrating multiple business systems while maintaining data integrity.
• Experience building and managing  CI/CD pipelines , deployment workflows, and cloud-hosted applications.
• Familiarity with  Shopify Oxygen , edge platforms, containerized deployments, environment configuration, and infrastructure troubleshooting. Experience with Shopify's GraphQL APIs (Admin and Storefront); ability to write, debug, and optimize complex queries

• Full-time availability (40 hours/week)

Nice-to-Haves

• Experience working in "Shopify-but-not-really-Shopify" environments where standard features required custom implementations
• Experience migrating Liquid storefronts to Hydrogen
• Experience managing large-scale product catalogs (100K+ SKUs) and SEO-sensitive migrations
• Familiarity with feed syndication, search integration (Algolia), or headless CMS (Storyblok) workflows
• React Router experience outside Hydrogen contexts

Ideal Candidate Profile

• Pragmatic problem-solver: You figure out how to make things work within real constraints. You don't default to "that won't work" or immediately escalate every obstacle—but you also don't spin wheels for days when a conversation would help.
• Full-stack fluency: You trace issues across the entire stack—from React components through GraphQL queries to Django backend logic—and implement end-to-end solutions.
• Judgment on autonomy: You know the difference between "I can handle this" and "I should discuss this first." You escalate strategically, not out of insecurity or habit.
• Adaptable to ambiguity: You receive "we need X" without a spec, ask the right clarifying questions, and either implement or flag complexity appropriately.
• Ecosystem navigator: You understand that "Shopify" in a Hydrogen + Algolia + Storyblok context is very different from "Shopify" in a Liquid theme context, and you can bridge that gap for stakeholders.
• Mentee-ready: You can work independently but recognize this is the second engineering role at the company; you're comfortable being the "reverse half" of a mentor relationship with the CTO.
