As IT & Security Manager, you will own Sentrycs’ end-to-end IT operation – infrastructure, systems, and support – across our Tel Aviv headquarters and our growing international footprint. This is a hands-on, high-visibility role in a company whose product is cybersecurity, so our own internal security posture has to be exemplary. 

You will work in close, ongoing partnership with our CISO: the CISO sets security strategy, policy, and risk priorities, and you are the operational owner who executes the resulting work plan day to day – implementing controls, running the cybersecurity processes, driving remediation, and reporting progress back. Think of this as the hands-on execution engine behind the CISO’s roadmap, combined with full ownership of core IT infrastructure and support. 

In This Role, You Will 

• Partner closely with the CISO to translate security strategy and risk priorities into a concrete work plan, and own execution of that plan across IT systems, infrastructure, and processes. 
• Manage day-to-day cybersecurity operations: access control and identity management, endpoint protection, patching, vulnerability remediation, monitoring, and incident response – in line with the CISO’s direction. 
• Own and manage Sentrycs’ global IT infrastructure – network, servers, endpoints, cloud environments (AWS/Azure/GCP), and SaaS tooling – across HQ and international offices. 
• Design and maintain secure network architecture (firewalls, VPN, segmentation, Wi-Fi) covering both standard office use and sensitive R&D/lab and testing environments, per security requirements set with the CISO. 
• Run day-to-day IT support and helpdesk operations: employee onboarding/offboarding, hardware provisioning, ticket resolution, and SLAs, as the team and headcount grow. 
• Own the IT budget: plan spend, evaluate and negotiate with vendors, ISPs, MSPs, and hardware/software suppliers, and control costs without compromising security or reliability. 
• Support the CISO on information security compliance and certification efforts (e.g., ISO 27001-aligned practices) and help prepare responses to customer, partner, and government security questionnaires and audits. 
• Support secure handling of sensitive defense- and government-related data, in line with export control and confidentiality requirements. 
• Own business continuity and disaster recovery planning for a company operating across multiple time zones and customer types (defense, government, critical infrastructure). 
• Drive IT projects end to end: cloud migrations, systems upgrades, MDM rollouts, and adoption of new collaboration and security tooling. 
• Partner with R&D, hardware, and QA teams on infrastructure needs for development, lab, and test environments. 
• Report regularly to the CISO and management on security work-plan progress, open risks, and IT operational health. 
• Build and mentor an IT support team as the company scales.
