About ROCTEL

ROCTEL is Ireland’s only Cisco Powered and Premier Service Provider Partner with global designation. In 2025, we celebrated 25 years in business, delivering secure, scalable, and intelligent network infrastructure to organisations across Ireland, the UK, and beyond.

We deliver high-availability connectivity, core network management, firewalls, collaboration tools, and secure WAN solutions for our clients. Our mission is to simplify complex technologies, enabling organisations to operate securely, productively, and cost-effectively.

As we continue to grow, we’re looking for a talented engineer to help bridge today’s critical network security operations with tomorrow’s AI-powered innovations.

Role Overview

This is a hybrid role combining hands-on network security engineering with forward-looking innovation in AI.

You’ll play a key role in maintaining and optimising secure, high-availability client networks, while also contributing to the design and development of intelligent, AI-enhanced security systems.

Working across both customer environments and internal projects, you’ll help ensure our clients remain ROCSOLID, while supporting the evolution of next-generation, AI-driven solutions.

Key Responsibilities

Manage and optimise Cisco-based security infrastructure, including firewalls, VPNs, and secure WAN environments
Conduct proactive threat detection using XDR and participate in SOC operations to analyze and respond to security events, with occasional fieldwork as needed.
Perform network upgrades, patching, and maintenance (including occasional out-of-hours work where required)
Collaborate with field engineers on client sites to support installations and troubleshooting
Support and enhance secure connectivity across multi-site client environments
Contribute to the design and development of AI-driven security solutions and intelligent automation systems
Work closely with internal teams to improve visibility, resilience, and performance across networks

Key Requirements

Degree in Engineering, Telecommunications, Networking, Cybersecurity, Computer Science, or a related field
Cisco CCNP certification (or equivalent hands-on experience with Cisco security technologies)
Strong experience in network security, including firewalls, VPNs, and secure infrastructure
Genuine interest in AI and its application within cybersecurity and network operations
Full driver’s licence and willingness to travel to client sites when required
Right to work in Ireland is essential

What We Offer

Opportunity to work with cutting-edge Cisco-powered technologies
Exposure to emerging AI-driven security and automation initiatives
Modern city centre offices
Competitive salary and performance-based bonuses
Flexible working
Pension contributions
Ongoing training and development

If you’re ready to innovate, learn, and grow with us, we’d love to hear from you.

Please send your CV and Cover Letter to [email protected] with the subject line “AI & Security Network Engineer – Ireland”.
