Why This Organisation
Our client is a globally recognised payments technology company processing billions of transactions annually across more than 175 countries. Their Belfast engineering team develops and maintains a high throughput payment gateway that handles millions of card transactions every single day, supporting customers from small businesses all the way through to 70,000 seat stadiums. One hundred percent uptime is not an aspiration here; it is the standard. This organisation takes engineering quality seriously because it has to. The systems are mission critical, the scale is significant, and the problems you would be working on are genuinely complex.

This is a hands-on Senior Software Engineer position at the heart of a high performing payments engineering team. You will design, build and maintain robust, scalable .NET applications and services, contribute to architectural and technical design discussions and work on high throughput, low latency systems where every line of code carries real weight. You will also be part of a collaborative Agile team, contributing to code reviews, CI and CD pipelines and automated testing, with real input into how the engineering function continues to improve.

- 4 or more years of software development experience
- Strong server side development experience in C# and .NET
- Experience building scalable web services and APIs
- Solid experience with SQL Server or other relational databases
- Experience working in a CI and CD environment using Jenkins, GitLab, Bamboo or similar

- Good understanding of software design principles and OO design
- Strong problem solving and communication skills
- Experience working in Agile delivery environments
- Must reside in Northern Ireland or commuting distance to Belfast, with the right to work in the UK on a permanent, full time basis
