About the project

We're developing a modern, scalable commerce platform built around Shopify's headless ecosystem. The system connects multiple services and APIs to deliver flexible, high-performance online experiences across multiple brands and regions.

About You

You're an experienced engineer with hands-on Shopify experience who enjoys working across the stack. You thrive in environments that value clean architecture, scalability, and thoughtful problem-solving, and you're comfortable making pragmatic decisions that balance technical depth with business goals.

Responsibilities

  • Design, build, and maintain full-stack features within a headless Shopify environment.
  • Integrate external services, APIs, and data sources to support product, marketing, and checkout workflows.
  • Contribute to architectural decisions that ensure scalability, performance, and maintainability.
  • Collaborate with cross-functional teams to deliver seamless customer journeys and internal tools.
  • Maintain robust testing, observability, and deployment processes.
  • Drive best practices in code quality, documentation, and team collaboration.

Requirements

  • 8+ years of professional experience
  • Shopify development experience including custom app and API integrations.
  • Proficiency in React, , and TypeScript, with an understanding of full-stack application design
  • Experience working with microservices, API integrations, and asynchronous data flows.
  • Understanding of headless commerce principles and decoupled front-end/back-end workflows.
  • Familiarity with CI/CD, automated testing, and version control best practices.
  • A systems-thinking approach — able to reason about data flow, architecture, and performance optimizations.
  • Bonus: exposure to event-driven systems, AI-assisted development tools, or commerce data integrations (PIM, ERP, CRM).

Why join us

  • Work on a modern commerce platform with meaningful technical challenges and global visibility.
  • Join a team that values clean code, thoughtful architecture, and continuous improvement.
  • Collaborate in a setting that encourages ownership, autonomy, and innovation.
  • Help shape a scalable ecosystem that supports evolving business needs.
