Essex | Outside IR35 | Flexible working available
We’re looking for an experienced Full-Stack Developer to deliver a package of enhancements to a suite of branded e-commerce websites. This is a contract role starting immediately, outside IR35, based in Essex with flexible working options.
The primary focus will be improving product search functionality by integrating Algolia Search, ensuring users get faster, more accurate results — even with typos or spelling errors. You’ll also help align the user experience with other platforms and support operational initiatives such as tiered pricing and stock accuracy.
The Role:

• Implement Algolia Search within ASP.NET (.NET Framework 4.8) websites
  
• Enhance product search UX, prioritising relevance and popularity of results
  
• Ensure accurate stock availability, including ring-fenced stock visibility
  
• Align features and UX with the wider group site (icons, order tracking, etc.)
  
• Enable case quantity ordering and tiered pricing functionality
  
• Deliver clear testing, documentation, and handover to the internal team
  

Tech Stack:

• ASP.NET (.NET Framework 4.8), C#
  
• JavaScript, HTML, CSS
  
• REST APIs
  
• Algolia Search integration
  

What we’re looking for:

• Strong experience integrating Algolia (or similar) into .NET websites
  
• Solid understanding of e-commerce product search challenges
  
• Commercial experience with mid-sized platforms
  
• Ability to deliver scoped enhancements independently
  
• Clear communication and documentation skills
  

Nice to have:

• Experience with B2B e-commerce or branded microsites
  
• Knowledge of stock logic/ERP-connected product data
  
• Familiarity with order and pricing workflows
  

Why apply?

• Outside IR35 contract
  
• Essex-based with flexible working
  
• Opportunity to deliver impactful search and UX improvements on live platforms
