Shopify Plus Full-Stack Developer

About The Role

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.

• 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.
