The opportunity

As a Cybersecurity Expert, you will serve as a senior individual contributor who advances the security of our services, platforms, and operations. You will apply broad technical expertise to identify material risks, assess complex environments, shape practical solutions, and guide stakeholders toward sound security decisions.

The role works across cybersecurity domains and business areas rather than being limited to a single technology or workstream.

Priorities may evolve as threats, technologies, and business needs change.

You will join an international, multidisciplinary security organization that combines technical depth with a strong understanding of business risk. We value collaboration, constructive challenge, knowledge sharing, and ownership. Our experts work across locations and security disciplines to improve resilience, support secure transformation, and enable the business to innovate with confidence. We invest in professional growth and expect every team member to share expertise, learn continuously, and contribute to the development of our security community.

• Excellent written and verbal communication skills, with the ability to influence both technical specialists and senior stakeholders.
• A strong drive to learn and continuously develop, combined with curiosity, a collaborative mindset, and a commitment to sharing knowledge.

• Professional security certifications such as CISSP, CCSP, CISM, OSCP, GIAC, or comparable credentials.
