# Senior Full Stack Engineer (.NET/React) - AI Services

PROJECT OVERVIEW Our client is building the software that hearing clinics run on patient records, bookings, hearing tests and sales. Clinic chains and hospitals use it every day. You join the team that owns the Sales domain: quote, invoice, insurance claim and payment. We are looking for a Senior Full Stack Engineer who ships business outcomes, not just tickets. You own features end to end - from why a clinic needs them, through design and build, to checking in production that they worked. AI coding agents are a normal part of every step of your work. Tech environment: C# / .NET 8.0, Azure Services (Azure SQL, AI Search, Service Bus, App Insights, Data Factory), Entity Framework Core, Docker, Kubernetes, MassTransit, React with TypeScript, plus growing use of Python for AI tooling and experimentation. IN THIS ROLE, YOU WILL Design, build and run full-stack features in the Sales domain: .NET services, event-driven integrations and React front end. Work with the Product Owner and QA from discovery onwards. Shape the spec and agree acceptance criteria before code is written. Find the gaps in a spec before you build. Close the small ones yourself and bring only business questions to
