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.
