Job description

Senior Full-Stack .NET Engineer | AI Agents & AzureIreland | Up to €90,000

Most “AI roles” still involve adding a chatbot to an existing product.

This one doesn’t.

There are seven specific finance workflows that have already been identified as strong opportunities for AI agents. The first agents have been built and are approaching release. This new engineer will help get them into customers’ hands and shape what comes next.

These aren’t generic copilots looking for a problem. They’re focused agents designed to take established, time-consuming finance processes and execute them properly.

You’ll be working across:

• C# and modern .NET
• Azure and cloud-native operations
• REST APIs and distributed services
• Microservices and event-driven architecture
• Docker and Kubernetes
• React, Angular or Vue
• AI-assisted and agentic product development

This is a genuinely hands-on role. They need someone who can move from a rough frontend through to the API, validate assumptions, troubleshoot problems across the stack and explain why they made a particular technical decision.

AI tools will absolutely be part of how the team works. The important bit is knowing what good engineering looks like, so you can tell when the output is useful and when it is confidently wrong. You don’t need years of production AI experience.

You’ll need to be based in Ireland. Dublin-based engineers will generally attend weekly, while there is more flexibility for people living elsewhere in Ireland. Critical Skills sponsorship can be supported.

If you’re a strong .NET engineer who wants to work on AI that solves an actual customer problem, this is worth a conversation.
