• Ensure adherence to internal security policies, standards, and legal requirements.


• Develop, monitor, and report security KPIs to continuously improve operations.

What You Bring

• 3–5 years of experience in information security, ideally in a security engineering or operations role.

• Relevant certifications such as CompTIA CySA+, SSCP, Security+, GSEC, or equivalent is a minimum.


• Analytical mindset, curiosity, and the ability to independently identify and resolve issues.


• Eligibility or willingness to undergo Swiss security clearance “PSP - Personensicherheitsprüfung”.


• Excellent communication skills with all levels of stakeholders, suppliers, and third parties – including face-to-face meetings, teleconferences, and presentations.


• A positive attitude and collaborative spirit, with the ability to thrive in multicultural teams.


• Business-fluent in English and German; any additional language is an asset.
