Lead & Senior Security Analyst - Global Security Operations

Location: Belfast | Permanent

Our client is growing their Global Security Operations team and is seeking both Lead and Senior Security Analysts to play a critical role in defending the organisation against cyber threats.

This is more than just monitoring dashboards - you'll be at the front line of threat detection, incident response, and security enhancement, working in a fast-paced, global environment where your expertise directly impacts the organisation's resilience.

If you thrive on solving complex problems, staying ahead of the evolving threat landscape, and making a tangible difference in security posture, this is the opportunity for you.

What You'll Be Doing

As part of the Security Operations team, you'll:

• Detect and defend - monitor alerts from SIEM, DLP, and threat intelligence platforms, distinguishing noise from genuine threats.

• Analyze and act - investigate vulnerabilities, identify malicious activity, and recommend remediation steps.

• Respond with impact - play an active role in incident response: containment, eradication, and recovery.

• Shape best practice - help refine and enhance incident response procedures, bringing lessons learned into the wider team.

• Strengthen defences - propose new detection rules, alerts, and analysis techniques to continually improve monitoring capability.

• Protect data - support DLP processes and contribute to compliance tasks.

• Record and report - document incidents, investigations, and outcomes with clarity and precision.

• Stay ahead - keep up-to-date with the latest cyber threats, tactics, and emerging technologies.

• Support operations - assist with configuration changes across firewalls, CASB, and other security tools, ensuring compliance with governance processes.

What You'll Bring

We're looking for professionals who combine technical know-how with proactive problem-solving and a collaborative mindset:

• Bachelor's degree in Computer Science, Information Security, or related field.

• Senior Analyst - 5+ years of relevant cybersecurity experience.

• Lead Analyst - 7+ years of relevant cybersecurity experience.

• Strong knowledge of core security principles, tools, and best practices.

• Practical experience with monitoring and security tools (SIEM, IDS/IPS, endpoint protection).

• Familiarity with incident response processes and playbooks.

• Strong analytical mindset and a keen eye for detail.

• Excellent communication skills, with the ability to work effectively across diverse teams.

What Will Make You Stand Out

• Experience with DLP solutions and data protection.

• Knowledge of compliance standards and regulatory requirements.

• Previous involvement in vulnerability remediation or infrastructure security hardening.

• A proactive approach to automating detection, response, or workflow improvements.

Why This Role?

This is your chance to work in a global, enterprise-scale security environment where your skills won't just be tested - they'll be developed. Whether you join as a Senior Analyst ready to deepen your expertise or as a Lead Analyst looking to take ownership of complex incident handling, you'll be part of a team that values continuous learning, innovation, and collaboration.

You'll be given the autonomy to make an impact while being supported by a team of skilled professionals who share the same mission: to stay ahead of threats and protect what matters most.
