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 wont 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.
