The business is moving its core booking platform to an Azure and modern .NET solution, while also building an AI-powered quotation and knowledge platform that will be central to how the organisation works. This is a hands-on senior engineering role and you'll be joining at a point where the architecture, delivery approach and product direction still matter. You'll design and ship production services, contribute to a structured strangler-fig migration, and use AI-assisted development tools such as Cursor and Claude Code as part of everyday engineering practice. The role would suit an experienced Senior Developer, or a strong Developer ready to step up in a collaborative, senior-led environment. What You'll Be Doing * Design, build and support cloud-based services in .NET 10 across Azure API Management, Azure SQL and the wider Azure platform. * Help modernise a business-critical booking platform using an incremental strangler-fig migration approach. * Work on anti-corruption layers, two-way data synchronisation, staged cutovers, validation and zero-downtime release patterns. * Build and maintain reliable CI/CD pipelines using Azure DevOps and GitHub Actions. * Develop secure services within the Entra ID identity plane for staff and customer authentication. * Contribute to AI-enabled quotation and knowledge tools, including human-in-the-loop quote drafting and retrieval-augmented knowledge features. * Collaborate closely with mobile, product and engineering colleagues where your APIs are consumed across different surfaces. * Take part in architecture discussions, code reviews and mentoring of graduate developers. ## Related Videos - [Blazor Unleashed: The Future of .NET Web Development](https://www.wearedevelopers.com/videos/1564-blazor-unleashed-the-future-of-net-web-development) - [Innovating Developer Tools with AI: Insights from GitHub Next](https://www.wearedevelopers.com/videos/1268-innovating-developer-tools-with-ai-insights-from-github-next) - [Keeping applications secure by evolving OAuth 2.0 and OpenID Connect](https://www.wearedevelopers.com/videos/100152-keeping-applications-secure-by-evolving-oauth-2-0-and-openid-connect) - [Develop enterprise-ready applications for Microsoft Teams with Azure resources on modern web technologies](https://www.wearedevelopers.com/videos/187-develop-enterprise-ready-applications-for-microsoft-teams-with-azure-resources-on-modern-web-technologies) - [Blazor – the new SPA Framework for everyone who hates JavaScript](https://www.wearedevelopers.com/videos/699-blazor-the-new-spa-framework-for-everyone-who-hates-javascript) - [Bringing AI Model Testing and Prompt Management to Your Codebase with GitHub Models](https://www.wearedevelopers.com/videos/1536-bringing-ai-model-testing-and-prompt-management-to-your-codebase-with-github-models) ## Related Articles - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Frontend Developer Salary in The UK](https://www.wearedevelopers.com/magazine/233-frontend-developer-salary-in-the-uk) - [7 Most Popular Web Developer Jobs in Europe](https://www.wearedevelopers.com/magazine/163-7-most-popular-web-developer-jobs-in-europe)
