IT Manager

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.

Requirements

• 5+ years of experience in IT management, including at least 2 years leading IT operations or a small team.
• Proven hands-on experience with network infrastructure, Windows and Linux server environments, and at least one major cloud platform (AWS, Azure, or GCP).
• Strong working knowledge of cybersecurity fundamentals: endpoint protection, identity and access management, network segmentation, and incident response, with the ability to execute a security work plan defined by a CISO or security leadership.
• Experience supporting a multi-site or international organization across different time zones.
• Hands-on experience administering Microsoft 365, MDM platforms, and IT ticketing/asset-management systems.
• Bachelor's degree in Information Systems, Computer Science, or a related field - or equivalent hands-on experience.
• Excellent English communication skills (written and spoken)
• Strong cross-functional collaborator, comfortable operating as the execution partner to a CISO or security function, with clear reporting and follow-through.
• A hands-on, service-oriented, “get it done” attitude, strong ownership, and the ability to work independently under pressure - a fit for Sentrycs' fast-paced, high-growth culture.

Nice to Have

• Prior experience working alongside a CISO or dedicated security function in a regulated or security-sensitive company.
• Experience in defense, cybersecurity, RF/wireless, or other regulated, security-sensitive industries.
• Familiarity with information security frameworks and compliance regimes (ISO 27001, SOC 2, CMMC).
• Scripting/automation skills (PowerShell, Python, or Bash) for IT process automation.
• Experience with SIEM, vulnerability management, or other security-monitoring tooling.
• Experience supporting hardware, embedded, or lab/test engineering environments.
