Job Description

About Swanky

Swanky is a Shopify Platinum Partner agency. We design, build and grow Shopify Plus stores for brands across the UK, Europe and beyond. Our work spans new builds, complex platform migrations, and ongoing optimisation for established merchants.

About the Role

This role sits within our Growth Accelerator division, where we work on retainer with a handful of key Shopify Plus accounts. The work is iterative and ongoing: performance optimisation, complex modular sections and components, checkout extensions, middleware integrations and continual improvement. You'll get to know your clients' stores deeply and deliver work that compounds over time.

You'll need to be comfortable working across the full stack, from Liquid templates and frontend JavaScript through to server-side logic, APIs and data flows. The work is deadline-driven, with multiple accounts running concurrently, so you'll need to track your time accurately, communicate clearly with clients, and take ownership of your delivery within each account.

Day to day, you'll:

• Build, test and deploy theme components, custom sections, checkout extensions and integrations for retainer clients
• Write clean, maintainable code across the frontend (Liquid, HTML, CSS, JavaScript) and backend (Node.js, APIs, serverless functions)
• Work with Shopify APIs (REST and GraphQL), third-party integrations and middleware
• Identify and implement performance optimisations across storefronts
• Participate in code reviews, giving and receiving constructive feedback
• Communicate directly with clients: providing updates, explaining technical decisions and managing expectations
• Track time accurately against accounts and tasks
• Contribute to improving our development processes and standards
  

About You

You're a full-stack developer with solid Shopify experience who does their best work when they know a codebase inside out. You're comfortable talking to clients, diligent with your time, and thrive when working to deadlines across multiple accounts. You care about code quality and performance, and you're looking for a role where you can go deep rather than wide.

Required

• 3+ years of commercial full-stack development experience
• 2+ years delivering Shopify or Shopify Plus projects
• Strong knowledge of Shopify Online Store 2.0, Liquid templating and the Shopify CLI toolchain
• Proficiency in HTML, CSS, JavaScript (ES6+) and TypeScript
• Backend experience with Node.js (or similar), including working with RESTful and GraphQL APIs
• Familiarity with serverless or cloud-based architecture patterns
• Experience with databases and relational data structures
• Comfortable with Git version control and branch-based workflows in multi-developer teams
• Strong client-facing communication skills: able to explain technical concepts clearly and manage expectations
• Disciplined approach to time tracking, task management and delivering to deadlines across concurrent workstreams
• A genuine interest in improving your craft and staying current with the Shopify platform
  
  

Nice to Have

• Experience building Shopify Checkout Extensions or Functions
• Experience with React, Remix or Next.js
• Familiarity with Alpine.js and Tailwind CSS
• Experience with Supabase or Firebase
• Exposure to Flutter for mobile development
• Knowledge of headless ecommerce and composable architectures
• Experience with Agile/Scrum delivery environments
• Specialism in performance optimisation, accessibility or web animation
