About the Role

We’re looking for a Full Stack Developer who helps us build, improve, and scale the digital foundation behind our business. This is a role with real ownership: you’ll work closely with E-Commerce, CRO, Marketing, and IT to turn ideas into fast, reliable, and customer-facing solutions.

Responsibilities

• Build and improve our Shopify Plus storefront, including Liquid, JavaScript/TypeScript, theme architecture, and custom functionality.
• Support projects across checkout, cart flows, apps, and customer experiences.
• Use modern AI coding tools as your daily driver to accelerate development, improve workflows, and help build internal tools and automations.
• Create and iterate on A/B tests and conversion improvements, working closely with our CRO and E-Commerce teams.
• Turn insights into practical changes that improve the customer journey.
• Contribute to our Shopify Plus infrastructure, including custom apps, Shopify Functions, APIs, tracking integrations, and automation workflows.
• Help keep our webshop fast, stable, and scalable by improving Core Web Vitals, code quality, accessibility, and overall frontend performance.
• Work closely with CRO, E-Commerce, Trade Marketing, and IT to translate business needs into clear technical solutions.

Requirements

• 1-3+ years of experience building web applications or e-commerce experiences.
• Ideally hands-on experience with Shopify Plus, Liquid, themes, or Shopify APIs.
• Comfortable with JavaScript/TypeScript, HTML/CSS, and modern frontend development.
• Actively use AI tools in your development workflow and know how to evaluate, improve, and validate AI-generated solutions.
• Like taking responsibility, working independently, and turning ideas into shipped features – while knowing when to ask for input.
• Focus on solving problems and delivering value.
• Know when a solution needs more depth and when a simple approach is the right one.
• Can communicate clearly with both technical and non-technical stakeholders.
• Comfortable working in English.
• Enjoy working with unclear requirements and turning them into concrete solutions.
• Document your work and care about maintainable code.
