Shopify Developer in London

We are seeking a highly technical and strategic remote Shopify Developer to join our client's web development team. This is a pivotal role focused on high-level architecture rather than simple maintenance. You will be responsible for auditing a large ecosystem of Shopify stores to identify inefficiencies, reducing reliance on third-party applications, and architecting a unified, reusable theming solution to be deployed across multiple storefronts.

The ideal candidate is an expert in the Shopify ecosystem, possessing deep backend knowledge of Shopify APIs, Checkout Extensibility, and private app development. This is a full-time, contractual, freelancer position for a trial period of 3 months while working at home. If you are a highly motivated and detail-oriented individual with experience and qualified based on the criteria below, we encourage you to apply.
