Master's in Computer Science: Specialisations, Careers & Salaries
An MS in Computer Science abroad is the broadest, most flexible route into a tech career — software engineering, AI, cybersecurity, systems. But here's the question most guides skip: if you already have a CS or IT bachelor's, what is the master's actually buying you? Sometimes it's deep specialisation. Often it's market access — the visa and the foot in the door at companies that hire abroad. This page covers the specialisations that matter, the roles and salaries, and an honest take on whether you need it. We're planners, not agents.
Is it worth it?
If you already hold a computer science degree, be clear-eyed about why you're doing this.
For specialisation — going deep in AI/ML, cybersecurity, or distributed systems that your bachelor's only touched. Good reason.
For market access — the degree is your route to a post-study work visa and a first job in the UK or Irish tech market. Also a good reason.
The warning: a broad, non-specialised CS master's that repeats your undergraduate is poor value. Pick a programme that genuinely adds a specialism or a placement.
What you actually study
- Core — advanced algorithms, software engineering, systems.
- A specialisation — AI & machine learning, cybersecurity, cloud/distributed systems, or software engineering.
- A substantial project or dissertation — increasingly with an industry placement, which is what employers reward.
