*Full-Stack Developer (Front-End Focused)* iSite is the UK’s largest Digital Media agency specialising in the creation, hosting and syndication of product data and video content/images for leading global brands, and providing eCommerce consultancy and development services. In short; we help our clients sell more online. *The Role* We are looking for a Full-Stack Developer with a passion for the front of the stack. You’ll be joining a multidisciplinary team where we prioritise performance, scalability, and elegant UI. You’ll have the autonomy to influence our architecture and help us transition toward next-gen frameworks. *What you’ll be doing:* * Crafting Experiences: Building lightning-fast, accessible interfaces using modern tools like Svelte and Astro. * Building Robust Backends: Developing scalable APIs and serverless logic within the .NET Core and Azure ecosystem. * Architecture & Innovation: Moving us toward an Islands Architecture to optimize content delivery for global brands. * Quality by Design: Writing clean, SOLID code supported by TDD and automated CI/CD pipelines. *The Essentials:* Modern Front-End: Deep experience in TypeScript and at least one modern framework (We have a handful of Angular projects in our stack but we are rapidly moving toward Svelte and Astro for performance). * The Core: Strong proficiency in C# and .NET Core. * Cloud Native: Experience deploying and scaling within Azure (Functions, App Services, Cosmos DB). * State & Styling: Mastery of modern CSS (Tailwind/SCSS) and state management patterns. *The "Nice to Haves":* * Experience with Headless CMS or eCommerce platforms. * Knowledge of SQL Server and NoSQL patterns (Cosmos DB). * An eye for UX/UI—you know when a transition feels off and how to fix it. * Any 3D/Computer Graphics experience would be useful as WebGL/AR projects are common also. *Why iSite?* We operate with Lean and Agile methodologies. You won't be a cog in a machine; you’ll be an owner of your code. We value curious developers—those who see a new tool like Astro and immediately want to know how it can improve our Lighthouse scores.
