Security Engineer Jobs

Cybersecurity is one of the fastest-growing career paths in Ireland, with 128 active roles reflecting the urgent demand for professionals who can protect increasingly complex digital infrastructure. Dublin dominates with 86 positions, while Cork (14), Limerick (6), and Galway (5) contribute meaningful regional clusters.

Accenture leads recruitment with 20 positions across its cybersecurity consulting practice at Grand Canal Square, Dublin 2. These roles span security operations, identity management, and threat intelligence — often embedded within client organisations across financial services, healthcare, and public sector. J.P. Morgan recruits 10 security professionals for its Dublin technology hub, covering application security, cloud security, and infrastructure protection for one of the world's largest financial institutions.

The physical security sector offers a distinct track. G4S has 5 positions for roles including field-based security operations. Tesco recruits security specialists for its retail operations. But the growth story is overwhelmingly in digital and application security: Canonical hires remotely for security engineers working on Ubuntu's enormous global install base. Whatnot, the live shopping marketplace, has 5 roles in its Dublin engineering office.

The consulting firms are aggressively building security practices. PwC at One Spencer Dock recruits for its cyber and privacy consulting teams. Endava adds software engineering-focused security positions. Arctic Wolf and Axway represent the specialist security vendor market, hiring for Security Operations Centre (SOC) and API security roles respectively.

What roles are available? The spectrum is broad — from Apprentice Fire & Security Engineer (an entry-level, earn-while-you-learn path) through to Senior IAM Engineers specialising in Identity Governance and Staff Product Security Engineers at scale-ups like Whatnot. The most in-demand skills include SIEM/SOAR platforms, identity and access management (IAM), cloud security architecture, penetration testing, and DevSecOps practices. Professional certifications such as CISSP, CISM, CEH, and CompTIA Security+ remain valuable differentiators, particularly for consulting roles that require demonstrating expertise to clients. With regulatory requirements like DORA (Digital Operational Resilience Act) and NIS2 driving investment across the financial services and critical infrastructure sectors, the demand for cybersecurity professionals in Ireland shows no sign of slowing.
