Director – cyber defence operations

Job Summary: Director – Cyber Defence Operations

Colt Technology Services is seeking a visionary cybersecurity leader to architect and scale a next-generation global Security Operations Center (SOC). Reporting directly to the Chief Security Officer, you will be responsible for transforming Colt’s cyber defence posture, integrating advanced threat intelligence, and leading a high-performing global team. In an era where telecommunications infrastructure is a primary target, this role offers the chance to redefine resilience for a company that connects thousands of businesses across the digital universe.

Requirements and Skills

• Leadership Experience: 8+ years in cybersecurity operations, with at least 3 years in a senior leadership role managing global teams.

• Technical Depth: Expert knowledge of security operations, threat intelligence (TI), and incident response frameworks.

• Network & OS Mastery: Deep understanding of intrusion detection, Windows/UNIX, web technologies, and—crucially—telecommunications networks.

• Proactive Defense: Hands-on experience developing custom detections, building high-fidelity alerting, and leading threat-hunting initiatives.

• Automation: Proficiency in cloud security operations and SOAR (Security Orchestration, Automation, and Response).

• Programming: Scripting experience in Python, PowerShell, Node.js, or JavaScript is highly desirable.

• Certifications: CISSP, GIAC, or equivalent professional certifications are a plus.

Role Overview

As Director of Cyber Defence Operations, you are the architect of Colt’s digital shield. Your mission is to move the SOC from a reactive monitoring unit to a proactive, intelligence-led operation. You will define the strategy for vulnerability management and incident response, acting as the ultimate escalation point for complex global threats. This role requires a “growth mindset”—the ability to navigate high-ambiguity environments and simplify complex technical risks for diverse stakeholders across the global organization.

Key Responsibilities

• Strategic Leadership: Drive the global cyber defence strategy aligned with business risk and lead the SOC transformation project.

• Intelligence Integration: Embed advanced threat intelligence into daily workflows to proactively identify and neutralize emerging threats.

• Vulnerability Management: Develop an automated, risk-based programme to significantly reduce the attack surface across global infrastructure.

• Incident Response: Oversee high-fidelity monitoring of network traffic and lead cross-functional responses to critical security incidents.

• Continuous Innovation: Stay ahead of evolving attack techniques and enhance detection logic and security tools.

• Stakeholder Management: Build collaborative relationships across the global business to ensure security is embedded by design.

What Colt Offers

• Autonomy & Impact: A culture that empowers leaders to create intelligent solutions without micromanagement.

• Flexibility: Support for flexible working hours and the option to work from home.

• Inclusion: A deeply inclusive culture with internal D&I networks, Mental Health First Aiders, and a global Family Leave Policy.

• Development: Extensive induction, mentoring, and continuous educational opportunities.

Application Tip: The Telco Advantage

Peer Note: Because Colt is a major network provider, they face unique threats (e.g., signaling attacks, large-scale DDoS, and infrastructure hijacking). In your application, emphasize any experience you have with carrier-grade security or protecting high-availability infrastructure.
