Medior AI Developer

About the job

As a Medior AI Developer you add full-time build capacity to the team. You pick up well-defined items from our roadmap and backlog, work them with limited supervision, and take them through to production. This is new development on products that are live and in daily use. The role is deliberately not a maintenance or BAU support seat, and it isn’t a blank-page greenfield project either. If you enjoy shipping features that real users feel the next day, you’ll be at home here. You’ll work closely with our Product Owner and senior engineers, take part in technical discussion and code review, and help raise the team’s standard through documentation and proactive knowledge sharing. The AI Apps team builds and operates 5CA’s internal platforms and client-facing customer-experience solutions on Microsoft Azure. We are mid-way through an ambitious modernization programme — migrating our core business platforms off the Power Platform onto a modern, Azure-native stack — and we apply AI inside those platforms as we go. This is applied AI engineering: we integrate Azure OpenAI, Azure AI Foundry, and Microsoft Copilot into production applications. We don’t train models or build ML pipelines — we ship working software that uses them. Position shift: 09:00 - 18:00 CEST.

Responsibilities

Build and deliver features and components of our platforms and AI solutions in C#/.NET and Azure Functions, owning well-defined items end-to-end through to production

Implement AI integrations using Azure OpenAI, Azure AI Foundry, and Microsoft Copilot, and contribute to prompt and grounding design

Design, develop, and test REST API integrations between our platforms and client systems

Work with Azure SQL and Entity Framework Core within our established data models and tenant-isolation patterns, and propose improvements where those patterns fall short

Work to the team’s engineering practices, including Git, GitHub Actions CI/CD, code review, and AI-augmented development, and review colleagues’ work

Instrument what you build, monitor it in production, and act on what the telemetry shows

Break assigned items into deliverable steps, provide realistic estimates, and flag risks to scope or timeline early

Document what you build to team standards and proactively share knowledge with the team

Refine requirements with the Product Owner and engineering colleagues, understanding the user and client impact of what you build
