The Problem You'll Solve

As a Senior Cyber Specialist, you'll be part of Prosus' Global Cyber team, helping our businesses identify, understand and manage their most critical cyber and technology risks.

You'll work across a diverse portfolio of businesses, delivering hands-on security testing, advisory and assurance projects that strengthen security.

You will use AI natively in everything you do. Your work will span a broad range of cybersecurity and technology domains, including:

• Delivering cyber risk assessments, security reviews and controls testing across complex technology environments.

• Conducting red teaming exercises and long-term Advanced Persistent Threat (APT) simulations to identify vulnerabilities and test organisational resilience.

• Assessing cloud infrastructure, data platforms, DevOps environments and CI/CD pipelines to identify security weaknesses and opportunities for improvement.

• Designing and facilitating cyber crisis simulations to test business preparedness and incident response capabilities.

• Providing practical, constructive recommendations that help management strengthen security without slowing down innovation or business growth.

• Partnering with technology and business leaders across our global portfolio to translate complex technical risks into meaningful business outcomes.

This is a full-time global role based in our Amsterdam (Zuidas) office, with up to 30% international travel.

Who You Are

• A hands-on cybersecurity professional with strong technical specialist experience in offensive security, security engineering or red teaming. You enjoy getting into the technical detail, investigating threats and identifying weaknesses rather than focusing solely on governance, risk and compliance.

• An AI and technology enthusiast who enjoys understanding how systems work, building harnesses and getting hands-on with complex technical environments.

• Comfortable navigating code, CI/CD pipelines, cloud environments and modern technology architectures.

• Entrepreneurial in your mindset, with exposure to both fast-moving start-ups and larger, more mature IT organisations, not afraid to use AI to get the job done.

• A confident communicator who can build trusted relationships, tell compelling stories and translate technical concepts into clear business language.

• Equally comfortable engaging with CTOs, CIOs, security leaders, architects, developers and system administrators.

• A global mindset, with interests beyond technology and an openness to travelling internationally, including to less conventional destinations.

What You Bring

• 3–7 years of relevant professional experience in cybersecurity, with a strong technical foundation in offensive security, threat intelligence, red teaming or related disciplines.

• Practical experience conducting or supporting penetration tests, security assessments, adversary simulations, threat investigations or other offensive security activities.

• Hands on work with AI harnesses and offensive AI models.

• Experience working with cloud technologies, data platforms and modern software engineering environments.

• Experience working across different organisational environments, ideally including both entrepreneurial and more established technology businesses.

• Relevant certifications such as CEH, OSCP, CISSP, CISM or CISA are welcome, but we value practical technical expertise and hands-on experience over certifications alone.
