Tasks

Client's ecommerce platform is a custom headless Shopify architecture built with React Router v7 (formerly Remix), Node. js, and Type
Script, organized in a Turborepo monorepo and deployed on Vercel. The system integrates Shopify, Builder. io, and a network of custom Node-based microservices that coordinate data from Salsify (PIM), Hub
Spot, and internal event pipelines. Multiple custom Shopify apps (admin, checkout UI extensions, functions) extend core capabilities, including advanced bundling logic and dynamic draft order workflows.

Requirements

• Deep Shopify experience — building against Admin, Storefront, Functions, and Checkout UI Extension APIs; understanding of platform constraints and best practices for scalable workarounds
• Advanced React / Remix / Node. js proficiency, with a strong understanding of SSR, routing, and composable architecture
• Full-stack Type
  Script expertise, including typing complex data models and designing maintainable shared packages across a monorepo
• Microservices & API integration — designing, deploying, and consuming Node-based services to orchestrate data and events between systems (Shopify, Salsify, Hub
  Spot, Builder. io)
• Strong
  - thinking mindset — able to reason about architecture, data flow, and the impact of design decisions across services
• Performance and reliability focus — experience with caching, code splitting, async lifecycles, and observability (Sentry)
• Proficiency with CI/CD pipelines and Git
  Hub automation (linting, tests, deployments)
• Comfortable in modern headless commerce environments — familiarity with Builder. io, Vercel, and related tooling
• Bonus: Experience with
  - driven systems, AI-assisted development (Cursor, Claude, Chat
  GPT, etc), or e
  Commerce data workflows (PIM/ERP)

The ideal candidate

• Senior engineers with
  - on experience pushing the limits of Shopify’s ecosystem, who can architect, implement, and maintain
  - scale integrations with clear thinking and precision. Someone who thrives in a modern Type
  Script-first,
  - driven environment and can make pragmatic, scalable technical decisions.
