Which master's specialisation suits a BTech graduate in Computer Science applying to Ireland with 6 years of work experience?

Six years of experience is enough that Ireland's employment-permit rules become as relevant to your specialisation choice as the coursework itself. Ireland's Critical Skills Employment Permit covers a wide range of ICT occupations, and Cybersecurity roles sit squarely within that list, which is why it edges out AI/ML and Cloud Computing despite all three scoring similarly on pure career fit.

Why Cybersecurity Edges Out AI and Cloud for This Profile

• Permit alignment: Ireland's Critical Skills Occupations List explicitly includes ICT security-related roles, and the current relevant-degree salary threshold sits at 40,909 euros for 2026.
• Experience leverage: Six years of networking, cloud, IAM or security-operations experience converts directly into a Cybersecurity master's, rather than needing new prerequisites.
• Safer fallback built in: If your six years were pure software development instead, Software Engineering remains an equally strong, lower-risk alternative.

My Advice

In my experience, candidates with six years of pure software-development experience sometimes force themselves into Cybersecurity because it sounds like the safer immigration bet, and that is a mistake if you have no security exposure at all. In that case, Software Engineering or Cloud Computing is a genuinely equal-ranked alternative that still benefits from Ireland's broad ICT permit coverage, without requiring you to learn an unfamiliar domain from zero.
