• Securing cloud environments through configuration management, data encryption, and adherence to cloud security best practices across public cloud platforms
• Promoting security awareness and best practices among IT teams and stakeholders, fostering a culture of security across the organisation

Requirements

• Minimum 2 years of relevant experience in a security engineering role, with a focus on infrastructure security, network security, or systems security
• Offensive Security Certified Professional (OSCP) is required
• Hands-on experience conducting network or infrastructure penetration testing, including scoping, execution, and reporting of findings to both technical and non-technical audiences
• Demonstrated ability to function as a cybersecurity SME, advising and influencing technical teams on security matters and translating complex security concepts for non-technical stakeholders
• Additional professional certifications such as CISSP, CEH, CISM, CCSP, or equivalent are an advantage
