Computer Science (Infrastructure) Ríomheolaíocht (Infreastruchtúr)

Computer Science (Infrastructure) is a future-focused, practical honours degree that equips you with essential skills in software development, IT infrastructure, networks and systems design – the building blocks behind modern digital technology. This course prepares you to design, develop and maintain the software and infrastructure that power everything from smart mobile apps and cloud services to enterprise systems used by global organisations.

Through hands-on learning, you will gain a strong foundation in programming, operating systems, networking, cloud computing, cybersecurity and systems administration. You’ll also explore how technology supports data storage, distributed systems, secure applications and infrastructure architecture. Whether you see yourself building secure networks, managing IT systems, or creating software solutions, this degree gives you the confidence to adapt as technology evolves.

A highlight of the student experience is the opportunity to take part in international exchanges, work placements and industry-relevant project showcases, including presenting your final year work to employers and tech experts. You’ll be supported to work independently and in teams, developing real technical skills and professional confidence for future careers.

Graduates of the programme are in demand across the IT and tech sectors with roles such as Software Engineer, Software Developer, Systems Administrator, Virtualisation Engineer, IT Security Specialist and Database Administrator at international companies and innovative start-ups. Many alumni also pursue postgraduate opportunities or specialise further in areas like cloud computing, cybersecurity and networking technologies.

This degree is suited to students who want a practical, adaptable and future-ready qualification in computing that prepares you for lifelong learning and a wide range of careers in the digital economy.

Having worked as a computer technician for a couple of years, I was made redundant and found I was being overlooked for jobs because of my lack of formal qualifications. I found the diversity of subjects and the pace of the course suited me very well. As part of the course I worked as an intern for the company with which I now work full-time. The course continued to be challenging and interesting throughout, and has given me a career path I would have never achieved on experience alone.

Graduates are qualified to pursue postgraduate studies to MSc, MPhil or PhD levels.
