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.
