Job Description

We are looking for a highly capable, hands-on Senior Full Stack Developer with 4–6 years of professional experience. This role is for a builder who understands both the how and why behind the code.

You will be responsible for building end-to-end web experiences, managing custom Shopify environments, and maintaining the backend systems and infrastructure that support them.

Infrastructure & Deployment

• Manage hosting and deployment environments on Heroku and AWS
• Configure and maintain Cron jobs for automated server-side processes
• Monitor system performance and troubleshoot infrastructure issues

System Integration

• Build and consume REST APIs to connect storefront systems with internal tools and third-party services
• Maintain reliable integrations and ensure smooth data flow across platforms

Requirements

• 4–6 years of experience in a professional full-stack development role
• Expert-level knowledge of Shopify development, including Liquid, Shopify APIs, and Shopify Functions
• Strong proficiency in PHP, SQL, and Vanilla JavaScript
• Experience managing Heroku environments and backend deployments
