Job description

Senior .NET Developer – Galway

Galway | Hybrid | Permanent

We're looking for a Senior .NET Developer to join a growing engineering team in Galway, working on a major transformation of a global SaaS platform.

This is a hands-on development role where you'll work with modern .NET, cloud technologies, microservices, event-driven architecture and AI-assisted development.

The Galway R&D centre is also a global AI hub, so you'll have the opportunity to work with AI coding tools, RAG and AI-powered product capabilities as part of your day-to-day development.

What You'll Do

• Design and develop cloud-native .NET services and REST APIs


• Build new functionality while modernising existing .NET applications


• Work with C#, .NET 8+, ASP.NET Core and Entity Framework


• Develop scalable microservices and event-driven applications


• Work with SQL Server and relational databases


• Use AI coding assistants such as GitHub Copilot as part of the development process


• Contribute to AI/ML and RAG-powered features


• Work with cloud technologies, CI/CD, Docker and Kubernetes


• Participate in code reviews, technical discussions and Agile ceremonies


• Collaborate closely with Product, Architecture, UX and QA teams

What We're Looking For

• Strong commercial experience developing software with C# and .NET


• Excellent knowledge of .NET 8+, ASP.NET Core and Entity Framework Core


• Experience building REST APIs and microservices


• Strong SQL Server experience


• Experience with cloud development, ideally Azure


• Knowledge of Docker, Kubernetes, Git and CI/CD


• Experience working in an Agile development environment


• Experience with modern front-end technologies such as React, Vue or Blazor


• Experience using AI-assisted development tools


• Strong problem-solving and communication skills

Nice to Have

• Experience modernising legacy .NET applications


• Experience in accounting, fintech or payments


• Kafka or other event-driven technologies


• GraphQL


• RAG, LLM or AI application development


• Automated testing / Playwright


• AWS experience

Why This Role?

This is an opportunity to join a growing Galway R&D operation and work on a significant technology transformation rather than simply maintaining an existing product.

You'll get exposure to modern .NET, cloud-native architecture, microservices and AI, while working on products used by thousands of customers internationally.

If you're a strong .NET engineer who enjoys hands-on development and wants to work with some of the newer AI-assisted engineering approaches, we'd like to hear from you.
