Overview
Join to apply for the Junior Cybersecurity Engineer role at Diacom Computer Telephony Limited
Diacom is a rapidly growing Managed IT Service Provider, delivering enterprise-grade IT solutions across networking, managed IT services, and voice telecommunications. Our tech stack includes HPE Aruba & Fortinet networking, Microsoft Windows, Microsoft Azure, and Microsoft 365, and an industry-leading cybersecurity platform in the MSP IT space. Our growth means we need specialists who can maintain the rapid response times our clients depend on. You’ll be joining a team that values curiosity, has autonomy, and demands technical excellence.
This role is a full-time, permanent position, based in our office in Park West, Dublin 12. Initially, this is a fully office-based role with direct mentoring to ensure you’re fully equipped for success in the role.
The Role
As the bridge between our Security Operations Centre (SOC) and engineering teams, you’ll ensure every validated alert leads to meaningful action. You’ll monitor and respond to alerts from our SOC, backup systems, Microsoft security tools, and RMM platforms — driving resolution, not just acknowledgment.
This is not a typical security analyst role: we want someone who asks why something happened and what the pattern means. You’ll develop an instinct for how big-picture IT designs are built and secured, becoming the person who detects and prevents major incidents before they escalate.
What You'll Do
* Monitor, analyse, and triage security and system alerts across our entire client base
* Identify patterns and correlations that signal larger systemic issues
* Escalate intelligently—based on context, not just predefined rules
* Ensure seamless handoff and resolution between SOC and engineering
* Collaborate with senior engineers to understand the root causes of security alerts, and their wider technical context
* Reduce false positives and improve our detection capabilities across our IT estates and product portfolio
* Monitor and verify all backup jobs across our estates, ensuring client data is fully protected
* Track issues through to resolution, documenting learnings for the team
* Design and execute fixes and solutions, or escalate intelligently when needed
What We're Looking For
We are looking for someone who:
* Is eager to learn and prove themselves in cybersecurity and IT operations
* Has a strong technical aptitude with the ability to quickly understand new systems
* Has a natural curiosity about how technology works and why it sometimes doesn’t
* Has excellent communication skills – you’ll need to translate technical issues for various audiences, including non-technical ones
* Can stay calm and think clearly when multiple alerts are firing
* Is self-reliant but knows when to escalate
* Has some experience with Windows environments, networking concepts, or security tools (training on specifics will be provided as part of this role)
Why This Role Matters
In this role, you will be looking at a lot of alerts, but you’ll also be:
* The guardian preventing client security breaches and downtime
* Learning from real-world security incidents that textbooks can never teach
* Positioned to move into security engineering and incident response roles
Growth Path
This role will evolve as you do. You’ll start by mastering our alert protocols and backup technologies. As you prove yourself, you’ll take on more complex incidents, automation projects, or specialisation in areas that interest you. We’re building this function for the long term and want someone who’ll develop and shape the role as it evolves.
Requirements
* Some IT/cybersecurity experience, or an applicable degree or industry certifications
* Strong analytical and problem-solving skills
* Genuine interest in cybersecurity and/or IT as a career path
Nice to Have
* Security+ or other entry-level security certification
* Familiarity with Microsoft PowerShell and Microsoft Windows & 365
* Scripting and automation experience
This role is a full-time, permanent position, based in our office in Park West, Dublin 12. At least initially, this is a fully office-based role with direct mentoring to ensure you’re fully equipped for success in the role.
