• Work with Cloudflare for delivery, caching, performance and security
• Contribute to technical architecture, technology choices and code quality
• Integrate web applications, forms and customer data with different CRM and marketing automation platforms
• Build responsive and accessible email templates for marketing, transactional and CRM-driven communication
• Use AI-assisted development tools responsibly to support planning, development, debugging, documentation and delivery across web projects
• Take ownership of features and solutions from idea to production
• Work particularly closely with design to create digital experiences where implementation quality matters
• Collaborate directly with clients and stakeholders to clarify requirements, manage expectations and support practical delivery decisions
• Contribute to how we continuously improve our development practices and ways of working

Experience

• 5+ years of professional development experience, with a strong focus on frontend and modern web development

• Comfortable working across the full stack, including Node.js, APIs and data modelling
• Hands‑on experience with headless CMS platforms and Shopify or comparable e‑commerce solutions
• Experience shipping production applications and working with CI/CD, cloud environments and modern development infrastructure
• Experience integrating third‑party APIs, CRMs, analytics, marketing tools or payment/e‑commerce systems
• Testing/QA awareness, especially component testing, integration testing, accessibility testing or structured QA before release

Who you are

• You enjoy building polished digital products and care about the details of how they work and feel
• You are strongest in frontend development but comfortable taking ownership across the stack
• You care about quality, performance and the people who will actually use what you build
• You are pragmatic and able to make good technical decisions based on context, balancing technical quality with user needs, business goals and delivery
• You enjoy working closely with designers, strategists, project leads, quality assurance and people from other disciplines
• You are curious about AI and how it is changing both digital products and software development, and eager to explore how it can be used in the products we build and the way we work
