Shopify | Front-End Engineer

Senior Full Stack Developer @ Cadence (Shopify, PHP, and Custom Systems)

We are looking for a highly capable, hands-on Full Stack Developer with 4–6 years of professional experience. This role is for a builder who understands the "how" and "why" behind the code. We aren't looking for someone who just stitches together React libraries; we need someone who can write clean, high-performance vanilla JavaScript and handle complex backend logic. You will be responsible for building end-to-end web experiences, managing custom Shopify environments, and maintaining the infrastructure that powers them.

Key Responsibilities No-Framework Frontend: Develop interactive, lightweight user interfaces using Vanilla JavaScript and jQuery. You must be able to solve complex UI challenges without relying on React, Vue, or Angular. Custom Shopify Development: Build and maintain bespoke themes using Liquid and implement advanced logic via Shopify Functions. Backend & Database Management: Design and maintain SQL databases and write server-side logic in PHP. Infrastructure: Manage hosting and deployments on Heroku and AWS, including the configuration of Cron jobs for automated tasks. System Integration: Build and consume REST APIs to connect our storefront with internal and external services. Technical Requirements Experience: 4–6 years in a professional full-stack role. Shopify Stack: Expert-level knowledge of Liquid, Shopify APIs, and the new Shopify Functions API. Languages: Deep proficiency in PHP, SQL, and "Plain Vanilla" JavaScript. DevOps: Experience managing environments on Heroku and handling database migrations/management. Automation: Ability to set up and troubleshoot server-side scheduled tasks (Cron). "Nice to Have" Skills Image Processing: Experience with programmatic image generation, layering, or synthesis (e.g., using GD library, ImageMagick, or Canvas). Complex Scripting: Experience handling heavy data processing or asset manipulation on the fly.
