• Partner closely with the IT team on infrastructure updates and serve as a senior escalation point for complex security issues.

• At least 5 years of professional experience in IT security, ideally within a highly regulated, research-heavy, or product-driven environment.
• ISO 27001 certification (e.g., Professional or Internal Auditor) or a similar recognized professional credential.
• Knowledge of security frameworks (with specific experience in NIS2 and an interest in supporting secure software/hardware development considered a strong plus)
• Solid expertise in network security (firewalls, VPN, routing), endpoint security, and security operations (SIEM, incident handling, log analysis).
• High flexibility to adapt to a startup environment, combining a senior "owner" mentality with the willingness to be hands-on during technical implementations.
