Full Stack Developer (Shopify/Hydrogen)

Job Title: Full Stack Developer (Shopify/Hydrogen)

Location: Remote

Schedule: 9am - 5pm Eastern Standard Time

Salary Range: Negotiable based on experience

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

They're not a "standard" Shopify setup - they 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

Must-Haves (Non-Negotiable)

• Strong frontend proficiency in HTML, CSS, and modern React
• Hands-on experience with Shopify Hydrogen (React Router-based), Storefront API, and headless commerce architecture
• Solid Python skills with Django experience; comfortable navigating monolithic codebases and API integrations
• Experience with CI/CD pipelines and deploying to serverless/edge platforms
• Experience with Shopify's GraphQL APIs (Admin and Storefront); ability to write, debug, and optimize complex queries
• Demonstrated ability to self-direct on clear technical tasks while recognizing when to escalate ambiguous requirements or architectural trade-offs
• Strong English communication skills; capable of explaining technical constraints to non-technical team members
• 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.

Tech Stack

• Shopify Hydrogen (React Router)
• React / HTML / CSS
• Python / Django
• PostgreSQL
• GraphQL (Shopify Admin & Storefront APIs)
• Algolia (Search)
• Storyblok (CMS)
• CI/CD & Deployment (Oxygen / edge platforms)
• Custom API integrations
