Shopify Plus Full-Stack Developer

Full Funnel Growth • New York, NY

About The Position

We’re looking for a skilled Shopify Plus Full-Stack Developer to join our team on a part-time, hourly basis. You’ll be the technical backbone of our e-commerce operations—building custom Shopify apps, developing and maintaining Shopify Plus storefronts, and owning the supporting infrastructure that powers our digital commerce ecosystem.
This isn’t just a theme development role. You’ll architect custom apps, integrate with third-party systems, deploy supporting microservices to serverless environments, and maintain the health of everything in production. We need someone who understands Shopify deeply and can build the custom tooling and integrations that take a Shopify Plus store beyond out-of-the-box capabilities.
Why Part-Time Works for This Role
Project-based workflow — Work comes in sprints and defined projects rather than constant full-time demand
Async-first culture — We communicate primarily through documentation and async tools, so you can work when it suits you
Flexibility — Set your own hours within reason; we care about output, not presence
Potential to grow — Hours may increase based on project needs and mutual fit
This is ideal for senior developers who want flexibility—whether you’re freelancing, have other commitments, or simply prefer part-time work.

Requirements

• Shopify Depth, Not Just Breadth
• You’ve done more than install apps and make minor theme tweaks. You understand Shopify’s architecture deeply—why things work the way they do, what the platform’s limitations are, and how to build around them. You can evaluate when to use a third-party app versus building custom.
• Full-Stack Ownership
• You’re comfortable across the entire stack. You can build a polished Liquid theme, develop a custom app with Polaris UI, deploy the backend to Lambda, and set up monitoring in Datadog. You don’t throw code over the wall—you own it through deployment and production.
• Production Mindset
• You think about what happens after code ships. You care about error rates, response times, and user experience in production. When something breaks, you want to know why and prevent it from happening again.
• Pragmatic Problem Solver
• Shopify has constraints. Every platform does. You can work within them creatively, evaluate trade-offs, and make decisions that balance ideal solutions with practical realities. You know when to build custom and when to use existing solutions.
• Clear Communicator
• You can explain technical concepts to non-technical stakeholders. You document your integrations. You ask clarifying questions before building something that doesn’t meet the need.
• Continuous Learner
• Shopify evolves constantly—new APIs, deprecations, features. You stay current with platform changes and can adapt your approach as the ecosystem shifts. You’re excited about Checkout Extensibility, Functions, and where the platform is heading.
• Reliable & Responsive
• Part-time doesn’t mean absent. You respond to messages within a reasonable timeframe, meet your commitments, and communicate proactively when priorities shift or blockers arise.
• Shopify Plus Platform (Required)
• 2+ years of hands-on Shopify development experience
• Deep proficiency with Liquid templating language (not just basics—complex logic, objects, filters)
• Experience with Shopify Plus tier features and capabilities
• Strong understanding of Shopify’s data model (products, variants, collections, customers, orders, metafields)
• Experience building and deploying Shopify Custom Apps
• Proficiency with Shopify CLI and modern app development workflow
• Working knowledge of Shopify Admin API (GraphQL strongly preferred)
• Experience with Storefront API for headless/custom storefronts
• Familiarity with Polaris component library and Shopify design patterns
• Understanding of Shopify’s app review requirements and best practices

• Familiarity with Shopify Functions (discounts, shipping, payment customizations)
• Knowledge of Shopify Scripts (legacy) and migration paths to Functions
• Experience with Shopify Flow automation
• Understanding of B2B on Shopify Plus (company accounts, price lists, payment terms)
• JavaScript/TypeScript Development
• 3+ years of professional JavaScript development
• Strong TypeScript proficiency
• Experience with Node.js backend development
• Proficiency with modern frontend frameworks (React preferred, given Shopify’s stack)
• Experience with Remix (Shopify’s preferred app framework) is a strong plus
• Understanding of RESTful and GraphQL API design and consumption
• Familiarity with authentication patterns (OAuth 2.0, JWT, session management)
• Infrastructure & DevOps
• Serverless & Cloud
• Experience deploying to serverless platforms (AWS Lambda, Vercel, Netlify, Cloudflare Workers)
• Understanding of serverless architecture patterns and limitations
• Familiarity with at least one major cloud provider (AWS preferred)
• Experience with managed databases (RDS, PlanetScale, MongoDB Atlas, DynamoDB)
• CI/CD & Deployment
• Hands-on experience with CI/CD pipelines (GitHub Actions preferred)
• Experience with Serverless Framework (serverless.com) or similar IaC tools
• Understanding of deployment strategies (blue-green, canary, rollbacks)
• Experience with automated testing in CI environments
• Monitoring & Observability
• Production experience with Sentry for error tracking and alerting
• Experience with Datadog or similar APM/monitoring tools
• Ability to set up dashboards, alerts, and incident response workflows
• Understanding of logging best practices in distributed systems
