Senior IT Manager

Seeking a Senior IT Manager to lead IT administration and infrastructure operations, covering systems administration, networking, security systems, and remote management. This is a highly autonomous, hands-on role — the person will be building out most of this infrastructure from the ground up, not maintaining an existing setup. Strong ownership, independent judgment, and self-direction are essential.

- 5+ years in IT administration/management, with senior or lead experience

- Proven ability to work autonomously and independently build IT infrastructure with minimal oversight — this role requires someone who can design and implement systems from scratch, not just operate existing ones

- Strong hands-on experience with Windows Server and Linux (Ubuntu/CentOS/RHEL)

- Networking expertise (TCP/IP, VLANs, firewalls, VPN protocols)

- Experience installing and managing IP camera/CCTV systems

- Familiarity with RMM/remote support tools

- Relevant certifications a plus (CompTIA Network+/Security+, CCNA, MCSA, RHCSA)

- Strong troubleshooting, prioritization, and project management skills

- Comfortable making architecture and vendor decisions independently

Systems Administration

- Manage and maintain Windows Server and/or Linux server environments

- Oversee patching, updates, and system hardening

- Administer Active Directory, Group Policy, and user/access management

- Manage virtualization platforms and backup/disaster recovery systems

Networking

- Design, configure, and maintain LAN/WAN infrastructure (switches, routers, firewalls) — largely from scratch

- Manage VPN infrastructure for secure remote access

- Monitor network performance and troubleshoot connectivity issues

- Establish network documentation and topology diagrams where none currently exist

Security & Surveillance

- Install, configure, and maintain IP security camera systems and NVR/DVR infrastructure

- Design network segmentation and cabling plans for camera/security systems as a new build-out

- Implement cybersecurity best practices (firewalls, endpoint protection, access controls) from the ground up

- Conduct periodic security audits and vulnerability assessments

Remote Management & Support

- Select, deploy, and manage RMM (remote monitoring and management) tools

- Provide remote and on-site technical support across sites

- Establish helpdesk operations and escalation processes
