• Monitor cloud and SaaS security posture, remediate misconfigurations, and review third-party integrations and access scopes.
• Implement and document technical security controls (runbooks, hardening guides) and support internal and external audits.

What we need:

• 5+ years of hands-on experience in IT infrastructure or cybersecurity engineering with a clear security specialization.
• Hands-on experience administering and hardening Linux, Windows, and macOS systems.
• Experience with endpoint protection and device management platforms.
• Solid understanding of networking fundamentals (TCP/IP, DNS, DHCP, VPN) and practical experience with firewalls and network security controls.
• Hands-on experience with identity and access management/SSO platforms with a security-first approach.
• Experience with vulnerability management tools and security monitoring and incident-response workflows.
• Understanding of common attack types and detection/prevention methods.
• Practical familiarity with recognized security frameworks and standards.
• Analytical mindset with the ability to assess risk and prioritize pragmatically.

• English proficiency (documentation, vendors, and external partners).

Would be an advantage:

• Ability to automate security and infrastructure tasks with scripting (Python, Bash, or PowerShell).
• Working knowledge of cloud security controls.
• Security certifications.
• Experience in enterprise or critical-infrastructure environments.

What you’ll get:

• Professional growth through working with cutting-edge defense technologies and exposure to international security best practices.
