About the role
Glass Atlas are looking for an experienced full-stack Shopify Developer to join our Commerce Technology team. You will work across a range of ecommerce clients, designing, building, launching and continually improving high-quality Shopify and Shopify Plus solutions. This is broader than a storefront or theme-development role: you will work across customer-facing experiences, server-side services, APIs, integrations and data flows, helping to understand client requirements, recommend pragmatic technical approaches and take responsibility for the quality of what we deliver.
Key responsibilities
The Shopify Developer is responsible for delivering robust, maintainable and high-performing solutions across the full Shopify technology stack. The role combines hands-on frontend and backend development with technical discovery, estimation, API and integration design, data modelling, quality assurance and production support. You will collaborate with developers, technical leads, designers, delivery managers and clients to turn commercial and functional requirements into effective Shopify solutions.
Full-Stack Shopify Development
- Build and maintain Shopify and Shopify Plus solutions across storefronts, custom applications, services and integrations.
- Develop bespoke themes and extend existing themes using Liquid, JSON templates, sections, blocks, HTML, CSS and JavaScript, while contributing to backend services where required.
- Translate designs and functional requirements into responsive, accessible and performant ecommerce experiences.
- Create flexible, reusable frontend components and backend services that are well structured, testable and maintainable.

- Support migrations and replatforming projects onto Shopify, including data, content and integration considerations.
Quality, Delivery & Collaboration
- Improve storefront performance, accessibility, SEO and overall technical quality.
- Use Git, Shopify CLI and agreed development and deployment workflows consistently.
- Review code, contribute to technical standards and help other developers deliver maintainable solutions.
- Estimate development work, contribute to technical discovery and communicate risks, dependencies and options clearly.
Live Support & Client Engagement
- Diagnose and resolve issues across existing Shopify implementations and live ecommerce sites.
- Support projects through development, QA, launch and post-launch optimisation.
- Work directly with clients where appropriate to understand requirements and explain technical solutions in plain language.
Platform Development & Continuous Improvement
- Keep up to date with changes to Shopify and recommend capabilities that could benefit our clients.
- Contribute to shared patterns, tooling, documentation and development practices across the Commerce Technology team.
- Build or extend custom Shopify applications and explore headless commerce, server-side services and enterprise integrations where appropriate.
