• A bachelor’s or master’s degree from a technical university with a focus on Information Technology, or a completed EFZ apprenticeship in IT with proven professional experience in the field of cybersecurity.
• 3–5 years of experience in information security, ideally in a security engineering or operations role.
• Strong Linux skills and solid understanding of network and endpoint security concepts.
• Familiarity with frameworks such as ISO 27001 ISMS, NIST, or BSI IT‑Grundschutz.
• Hands‑on experience with SIEM platforms (experience with Elastic preferred).
• 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.
