The beautiful tip of the iceberg
Most of what we build you'll never see. This is the part you can.
We have built with Blazor since its first release and run it in production for insurance, travel, health and the trades, alongside our own products. This role leads that work on .NET 10 and ASP.NET Core: component architecture, performance, accessibility and the release engineering that keeps a front end safe to change every week for years.
Server, WebAssembly and .NET MAUI Blazor Hybrid applications with ASP.NET Core APIs behind them.
Component libraries, state management, rendering performance, virtualisation and WCAG across large line-of-business screens.
Static server rendering, streaming and interactive modes per page, not by default.
Blue-green slots on Azure App Service, regression suites that gate every swap, rollback in seconds.
Web Forms, MVC and WPF front ends moved onto Blazor release by release, without a big-bang rewrite.
Reviewing code across the team and raising the bar without raising your voice.
Held and current on the day you apply. Every engineer applying for a role at Assemblysoft needs a current Microsoft Azure certification, and we verify it on Microsoft Learn or Credly before the first conversation. Include a link to your transcript or badge with your application.
Exams, study time and annual renewals for the Microsoft credentials your role needs, and the next tier when you are ready for it.
Work from home across the UK with a Bournemouth base to meet in; contract roles, full or part time.
£300–£600 a day depending on role and experience, and a non-corporate team of senior engineers who review each other's work.
Regulated, business-critical and long-lived: healthcare, insurance, transport, trades. Not throwaway builds.
Applications without proof of the required certification are not progressed, so please include it first time.
Who you are, what you have built or supported, and why this role. CV as Word or PDF.

Exam AZ-305. Required for our architect role and for anyone who signs off an Azure design.
Exam AZ-400. Preferred for engineers who own pipelines, environments and releases.
Exam AZ-204. The minimum for every developer role: ASP.NET Core and Blazor on Azure.
Exam AZ-104. The prerequisite for the Solutions Architect Expert certification.
Exam AZ-900. A useful start, but on its own it does not meet the requirement for any of our roles.
