Job Description

As a Red Team Specialist, you'll work in close collaboration with our Blue Team, emulating real-world threat scenarios to assess and improve our overall security posture.

Our environment is as diverse as it is innovative, requiring a creative and adaptive mindset. From our 5G radio networks to our eCommerce platforms and warehouse systems, you'll navigate a range of technologies and environments. Success in our Red Team means adapting traditional attack techniques to fit this diverse landscape while emulating our threat actors.

• Collaborate with our Security Incident Response Team to enhance detection and response capabilities.
• Work closely with our Infrastructure Security Team to propose defensive improvements across our varied environments, including our mobile networks and cloud systems.
• Work alongside non-technical teams to propose enhancements and additions to existing policies and processes.
• Take part in our gamified collaboration exercises.
• Stay informed on current security trends, advisories, publications, and academic research relevant to our organisation and the broader telecommunications industry.

What You’ll Bring

• Experience in cybersecurity roles such as Red Team Specialist, Ethical Hacker, Security Consultant, Penetration Tester, or similar.
• In-depth understanding of the MITRE ATT&CK framework with the ability to utilise threat intelligence to create relevant Red Team scenarios.
• Proficiency in scripting and programming languages like Python, Go, and Ruby to automate tasks and create custom security tools.
• Command-line experience with Linux-based operating systems
• Experience exploiting vulnerabilities in web applications, cloud environments Linux and/or MacOS workstations, and software supply chains.
• Strong understanding of telecommunications systems, including familiarity with RF (Radio Frequency) concepts, wireless network architectures, and mobile communication standards like 4G, and 5G.
• Experience with field-based and hands‑on technical tasks within safety regulations.
• Proficiency in a range of security testing tools and methodologies.
• Hands‑on experience with at least one of the major cloud providers.
• An adversarial mindset with the ability to think like an attacker.
• Excellent and professional communication skills (written and verbal) with an ability to articulate complex topics in a clear and concise manner.

• CISSP (Certified Information Systems Security Professional)
• OSEP (Offensive Security Experienced Penetration Tester Certification)
