Overview

At Viatel Technology Group, we know that great technology is important, but it's the people behind it that make the real difference.

For more than 26 years, we've helped organisations across Ireland get the most from their technology through communications, cloud, networking, cybersecurity, and digital services. Our role is simple: to take the complexity out of technology so our customers can focus on running and growing their businesses.

Today, more than 300 people work across the Viatel Group, bringing expertise, teamwork, and a customer-first mindset to everything we do. We're proud to have been recognised as a Deloitte Best Managed Company and Guaranteed Irish Technology Company of the Year 2024.

We're committed to building a workplace where people feel supported, valued, and trusted to do their best work. We welcome different perspectives, invest in learning and development, and create opportunities for people to grow their careers.

If you're looking to join a company that values its people as much as its customers, we'd like to hear from you.

The Role:

The Security Operations Analyst delivers high-quality security monitoring and incident response support to customers. The role is designed for motivated individuals who can manage multiple alerts and investigations in a fast-paced environment while continuing to learn and adapt to evolving security procedures and threats.

The ideal candidate will have experience supporting and securing Microsoft Cloud environments, with knowledge of endpoint, server, and network security technologies. This includes Microsoft 365 security, XDR, identity and access management, firewalls, and virtualised infrastructure. The role monitors alerts, investigates low and medium severity incidents, and triages high and critical alerts before escalation. Experience with data protection, backup, replication, and disaster recovery is advantageous.

This role sits within the Security Operations (SecOps) Team in the Service Centre Department of Viatel Digital Services. It requires 23 years experience with Microsoft Azure, Microsoft 365 security, XDR technologies, and security monitoring platforms, plus a basic understanding of frameworks such as NIS2. Candidates should show a commitment to developing skills in cyber security, threat detection and response, automation, and AI-driven security capabilities.

Manage assigned incidents and service requests, ensuring prompt, high-quality customer service and engagement.

Provide professional and timely support in relation to customer security alerts and incidents.

Fulfil service requests following the defined process within the agreed SLA timeframes.

Monitor security platforms for alerts, suspicious activity and indicators of compromise.

Ensure tickets are updated with accurate notes, actions taken, and escalation details.

Triage high and critical alerts to identify false positives or benign activity before escalation.

Assist in resolving incidents with engagement with internal IT teams and 3rd party providers.

Promote, develop, and maintain a positive experience to the customers.

Comply, maintain, and promote information security within Viatel.

Build strong and valued customer relationships with assigned customers.

Understand customer priorities and ensuring services delivered are aligned accordingly.

Maintain high customer service standards in a security operations environment.

Identify service improvement opportunities and proactively recommend enhancements.

Develop and instil a positive, collaborative and customer-focused culture.

Assist with evaluating new technologies, services and processes.

Maintain and develop technical certifications.

Requirements:

A minimum of 23 years experience in IT support, security operations, infrastructure support, cloud administration, or a related technical role in ICT Managed Services (MSP).

Focused on delivering exceptional technical support service.

Demonstrable experience in delivering technical support services meeting SLA/KPI objectives.

Ability to manage multiple customers and priorities simultaneously.

Experienced in managing and improving technical services.

Good knowledge of Microsoft Cloud, technical support services and tools, cybersecurity tools & security best practices.

Strong communication and client-facing skills with a customer-first mindset.

Ability to investigate low and medium severity alerts and identify when escalation is required.

Excellent troubleshooting and analytical skills.

Highly organised with strong attention to detail whilst being proactive and improvement-focused.

Professional, approachable and supportive.

Strong communication and interpersonal skills and ability to lead by example.

Strong analytical and problem-solving skills.

High level of flexibility, enthusiastic, willingness to learn and develop.
