Senior Software Developer Location: London - hybrid, 3 days per week in the office Salary: c£65,000 - £75,000 + bonus The Opportunity - Senior Developer - Cloud Platform & AI We're recruiting for a Senior Software Developer to join a small, highly capable technology team delivering a major legacy-to-cloud transformation. 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. What We're Looking For * Strong hands-on software development experience, ideally 6-10 years, with the majority in .NET/C#. * Recent experience with modern .NET, ideally .NET 8 or later. * Blazor experience. * Strong Azure experience, including App Service or Container Apps, Azure SQL, API Management and Azure DevOps pipelines. * Experience modernising legacy systems, ideally using strangler-fig or similar incremental migration approaches. * Good understanding of REST API design, microservices and event-driven architecture patterns. * Practical day-to-day use of AI-assisted development tools such as GitHub Copilot, Cursor, Claude Code or similar. * Identity and authentication experience, including Entra ID/Azure AD, OAuth2 or OIDC. * Comfortable working with SQL Server or Azure SQL data modelling, performance and migration activities. * Clear communication skills and the confidence to work in a small permanent team where engineers take ownership from design through to delivery. Useful Additional Experience * Exposure to React or React Native, particularly where APIs support web or mobile products. * Experience with retrieval-augmented generation, vector search or integrating LLM-based features into production products. * Experience working in a scale-up, transformation programme or small permanent technology team. Salary: c£65,000-£75,000, with some flexibility. For further information, or to apply, please send your CV to Wayne Young at Young's Employment Services Ltd.
